Description
本発明における共重合体（Ｂ）は、ブチル（メタ）アクリレートおよび／またはブタジエン５〜４０重量％、アクリロニトリル、スチレン、α−メチルスチレン、フェニルメタクリレート、メチルメタアクリレート、マレイミド、N−フェニルマレイミド、N−シクロヘキシルマレイミドから選ばれた少なくとも1種の単量体９５〜６０重量％からなる単量体混合物を重合して得られた共重合体である。
ブチル（メタ）アクリレートおよび／またはブタジエンが５重量％未満（アクリロニトリル、スチレン、α−メチルスチレン、フェニルメタクリレート、メチルメタアクリレート、マレイミド、N−フェニルマレイミド、N−シクロヘキシルマレイミドから選ばれた少なくとも1種の単量体が９５重量％を超える）では十分な打ち抜き強度が得られず、またブチル（メタ）アクリレートおよび／またはブタジエンが４０重量％を超える（アクリロニトリル、スチレン、α−メチルスチレン、フェニルメタクリレート、メチルメタアクリレート、マレイミド、N−フェニルマレイミド、N−シクロヘキシルマレイミドから選ばれた少なくとも1種の単量体が６０重量％未満）と最終製品に求められる剛性が不足する傾向にあるため好ましくない。
また、本発明における共重合体のガラス転移温度については何ら制限はないが、２０℃以上であることが好ましく、特に最終製品の着色や成形性の点から３０〜１２０℃であることが好ましい。
なお、ガラス転移温度については、上記にて使用する単量体の種類および使用比率により任意に調整することが可能である。また、ガラス転移温度ついては、セイコーインスツルメンツ社製 示差走査熱量計（ＤＳＣ６２００）を用い、窒素気流下で開始温度０℃、昇温速度２℃／分の条件により測定した。
The copolymer (B) in the present invention contains 5 to 40% by weight of butyl (meth) acrylate and / or butadiene, acrylonitrile, styrene, α-methylstyrene, phenyl methacrylate, methyl methacrylate, maleimide, N-phenylmaleimide, N - a copolymer obtained by polymerizing at least one monomer 95 to 60 consisting wt% monomer mixture selected from cyclohexyl maleimide.
Less than 5% by weight of butyl (meth) acrylate and / or butadiene (at least one selected from acrylonitrile, styrene, α-methylstyrene, phenyl methacrylate, methyl methacrylate, maleimide, N-phenylmaleimide, N-cyclohexylmaleimide) When the monomer exceeds 95% by weight, sufficient punching strength cannot be obtained, and butyl (meth) acrylate and / or butadiene exceeds 40% by weight (acrylonitrile, styrene, α-methylstyrene, phenyl methacrylate, methyl). (At least one monomer selected from methacrylate, maleimide, N-phenylmaleimide, and N-cyclohexylmaleimide is less than 60% by weight) and the rigidity required for the final product tends to be insufficient.
Moreover, there is no restriction | limiting about the glass transition temperature of the copolymer in this invention, However, It is preferable that it is 20 degreeC or more, and it is especially preferable that it is 30-120 degreeC from the point of coloring of a final product or a moldability.
In addition, about glass transition temperature, it is possible to adjust arbitrarily by the kind and usage ratio of the monomer used above. Further, the glass transition temperature was measured using a differential scanning calorimeter (DSC6200) manufactured by Seiko Instruments Inc. under the conditions of a starting temperature of 0 ° C. and a heating rate of 2 ° C./min under a nitrogen stream.
