Definitions
- the present invention relates to a prepreg and a laminate used for a printed wiring board for forming an electric circuit.
- a resin composition having a low dielectric constant and a low dielectric loss tangent such as a fluorine resin, a cyanate ester resin, a polyphenylene ether resin, or a vinyl compound mainly containing styrene is used.
- a resin composition having a low dielectric constant and a low dielectric loss tangent such as a fluorine resin, a cyanate ester resin, a polyphenylene ether resin, or a vinyl compound mainly containing styrene is used.
- a laminate for a printed wiring board uses a prepreg obtained by uniformly dispersing components in a resin composition in an organic solvent, impregnating or applying the obtained varnish to a substrate such as glass cloth, and drying. Produced.
- a low-polarity resin such as polyphenylene ether is often used as the main component of the resin having low dielectric loss tangent, and the above-mentioned organic solvent is also low-polarity toluene according to the polarity of the main component (for example, Patent Document 3). reference).
- toluene tends to be used from the viewpoint of environmental pollution, and it is required to use another solvent.
- it is not generally used to use a polar solvent as a resin component for such a low dielectric loss tangent, and the effect of residual solvent in the prepreg when using a polar solvent on the prepared prepreg, etc. Not enough consideration has been made.
- This invention makes it a subject to provide the prepreg which implement
- the present inventors have determined that the dielectric loss tangent at 10 GHz of the laminate produced using the prepreg is set to 0. by setting the residual amount of the polar solvent in the prepreg to 3% by mass or less. As a result, the present invention has been reached.
- the present invention [1] A prepreg produced by impregnating or coating a base material with a resin composition containing polyphenylene ether as a main component, an inorganic filler and a polar solvent, and then performing a drying step,
- the content of the polar solvent in the prepreg is 3% by mass or less
- the polyphenylene ether is represented by the general formula (4): (Wherein — (O—X—O) — represents the general formula (5): (R 21 , R 22 , R 23 , R 27 , R 28 may be the same or different and are an alkyl group or phenyl group having 6 or less carbon atoms. R 24 , R 25 , R 26 are the same or different.
- R 29 , R 30 , R 31 , R 32 , R 33 , R 34 , R 35 , R 36 may be the same or different and are a hydrogen atom, an alkyl group having 6 or less carbon atoms, or a phenyl group.
- B- is a linear, branched or cyclic divalent hydrocarbon group having 20 or less carbon atoms. It consists of the structure represented by.
- R 39 and R 40 may be the same or different, and are an alkyl group or phenyl group having 6 or less carbon atoms.
- R 37 and R 38 may be the same or different, and are a hydrogen atom or 6 or less carbon atoms. It is an alkyl group or a phenyl group.
- One type of structure or two or more types of structures are randomly arranged. a and b each represents an integer of 0 to 100, at least one of which is not 0.
- a printed wiring board including an insulating layer and a conductor layer formed on a surface of the insulating layer, wherein the insulating layer includes the prepreg according to any one of [1] to [13]. Including printed wiring board. Is provided.
- the prepreg of the present invention achieves a low dielectric loss tangent when a laminated board is produced, is suitable for a printed wiring board material corresponding to high density, and has extremely high industrial practicality.
- the prepreg of the present invention can be stably produced during the production of the prepreg or after the production, the phenomenon that the resin powder falls off from the prepreg and the powder fall off are suppressed.
- the present invention is a prepreg produced by impregnating or applying a varnish containing a resin composition containing polyphenylene ether as a main component, an inorganic filler and a polar solvent to a substrate, and then performing a drying step,
- the present invention relates to a prepreg in which the content of the polar solvent in the prepreg is 3% by mass or less, and a dielectric loss tangent at 10 GHz of a laminate produced using the prepreg is 0.001 to 0.007.
- polyphenylene ether As polyphenylene ether, general formula (1): (In the formula, R 1 , R 2 , R 3 , and R 4 may be the same or different and each represents an alkyl group, aryl group, halogen, or hydrogen having 6 or less carbon atoms.) It is preferable that the polymer comprises at least a repeating unit represented by:
- the polymer has the general formula (2): (R 5 , R 6 , R 7 , R 11 , R 12 may be the same or different, and are an alkyl group or phenyl group having 6 or less carbon atoms. R 8 , R 9 , R 10 are the same or different.
- R 13 , R 14 , R 15 , R 16 , R 17 , R 18 , R 19 , R 20 may be the same or different and are a hydrogen atom, an alkyl group having 6 or less carbon atoms, or a phenyl group.
- A- is a linear, branched or cyclic divalent hydrocarbon group having 20 or less carbon atoms.
- It may further contain a repeating unit represented by:
- a modified polyphenylene ether partially or wholly functionalized with an ethylenically unsaturated group such as a vinylbenzyl group, an epoxy group, an amino group, a hydroxyl group, a mercapto group, a carboxyl group, and a silyl group is used. You can also. These may be used alone or in combination of two or more.
- the method for producing the modified polyphenylene ether is not particularly limited as long as the effects of the present invention can be obtained.
- a product functionalized with a vinylbenzyl group is obtained by dissolving a bifunctional phenylene ether oligomer and vinylbenzyl chloride in a solvent, reacting by adding a base with heating and stirring, and then solidifying the resin.
- Those functionalized with a carboxyl group are produced, for example, by melting and kneading an unsaturated carboxylic acid or a functionalized derivative thereof with polyphenylene ether in the presence or absence of a radical initiator.

で表される変性ポリフェニレンエーテルを含むことが特に好ましい。
また、このような変性ポリフェニレンエーテルは、例えば、三菱ガス化学(株)(OPE-2St 1200など)から入手することができる。
ここで、樹脂組成物の量とは、ワニスにおける無機充填材及び溶媒を除いた各成分の合計質量をいうものとする。
この中でもビスフェノールA型エポキシ樹脂、フェノールノボラック型エポキシ樹脂、クレゾールノボラック型エポキシ樹脂、ナフタレン骨格変性したノボラック型エポキシ樹脂が好ましい。
スチレンオリゴマーの製法としては、例えば、ジビニル化合物との共重合、過酸化物の併用や放射線処理等が挙げられるが、これらに限定されず、例えばスチレンモノマーとジビニルベンゼンを使用し、重合触媒下で懸濁重合、又は溶液重合などにより製造する方法が挙げられる。
本発明で使用されるスチレンオリゴマー粉末の形状は、特に限定されないが、例えば、球状、不定形状等、何れも使用可能である。
プリプレグの製造時における乾燥条件は、乾燥後のプリプレグ中の残存極性溶媒量が3質量%以下となるようにするものであれば特に限定されないが、以下の例を挙げることができる。
基材に含浸させるプリプレグの大きさは、幅100~600mm、長さ200~1000mmであることが、残存溶媒量を効率的に減らせる観点から好ましく、幅300~550mm、長さ300~700mmであることがより好ましい。
乾燥方法としては、5秒~10分の間室温下で乾燥させた後、窒素気流による乾燥、スチーム式等の熱源を用いた乾燥方法が好ましい。
乾燥温度はプリプレグにおける溶媒の残存量と、樹脂組成物の硬化を促進させない観点から、120~220℃の範囲で行うことが好ましく、150~200℃の範囲で行うことがより好ましい。
乾燥時間は、溶媒の乾燥効率と樹脂組成物の硬化を促進させない観点から、2~15分で行うことが好ましく、3~10分で行うことがより好ましい。
また、乾燥時の圧力としては減圧でも常圧であってもよいが、コスト的な観点から常圧で行うことが好ましい。
温度計、攪拌器、滴下漏斗及び還流冷却器を取りつけた反応器を予めブラインにより0~5℃に冷却しておき、そこへ塩化シアン7.47g(0.122mol)、35%塩酸9.75g(0.0935mol)、水76ml、及び塩化メチレン44mlを仕込んだ。
この反応器内の温度を-5~+5℃、pHを1以下を保ちながら、撹拌下、式(2)におけるRがすべて水素原子であるα-ナフトールアラルキル樹脂(SN485、OH基当量:214g/eq.軟化点:86℃、新日鐵化学(株)製)20g(0.0935mol)、及びトリエチルアミン14.16g(0.14mol)を塩化メチレン92mlに溶解した溶液を滴下漏斗により1時間かけて滴下し、滴下終了後、更にトリエチルアミン4.72g(0.047mol)を15分間かけて滴下した。
滴下終了後、同温度で15分間撹拌後、反応液を分液し、有機層を分取した。得られた有機層を水100mlで2回洗浄した後、エバポレーターにより減圧下で塩化メチレンを留去し、最終的に80℃で1時間濃縮乾固させて、α-ナフトールアラルキル樹脂のシアン酸エステル化物(α-ナフトールアラルキル型シアン酸エステル)が23.5g得られた。
