Abstract
Description
本発明は、成形材料を製造するための新規のポリ(メタ)アクリラートに関する。特に本発明は、再度の共重合が不可能である成分を、開裂の際に、 −たとえ遊離するにしても− 極めてわずかな程度でのみ遊離するに過ぎないエステル基を有する、新規の(メタ)アクリラートに関する。成形材料のための新規のポリ(メタ)アクリラートを製造する際にこのようなモノマーを共重合することによって、その耐熱変形性は最小限の変化にとどまるか、もしくはむしろ改善される。
EP0113105には、PMMAと、無水マレイン酸、α−メチルスチレン及びMMAからのターポリマーとからの混合物が記載されている。配合工程が必須であることに加え、比較的長い耐候試験下で成形材料が明らかに脆化する点が不利である。該ブレンドの改良については、EP1742997に詳論されている。ここでは、PMMAと、無水マレイン酸、スチレン及びMMAからの比較的短鎖のターポリマーとからの混合物が存在している。しかしながら、この系も耐熱変形性に関して十分な改善を要する。さらに、該系はスチレンを含有しているが、スチレンは当業者に公知の通り耐候性に不利な影響をもたらす。ポリメタクリラート中の構造単位としての無水マレイン酸とビニル芳香族化合物との組合せは、ポリメタクリラート成形材料の熱安定性の改善のためにしばしば用いられる解決策である。しかしながら該解決策は根本的にまだ不十分であり、それというのも、確かにこの方法でガラス転移温度を高めることはできるが、しかしながら潜在的な非相容性、ひいては相分離を甘受しなければならないためである。さらに、熱分解の問題への影響も極めてわずかである。DE29504693U1では、有機化合物、より厳密には有機ホスファイトの添加によるアプローチが考慮されている。しかしながら、低分子化合物はマイグレーションの傾向を示し、かつ熱負荷下での比較的長期の安定化を保証し得ない。そのような配合解決策として、共配合することなくそれ自体で耐熱変形性を有するように変性されたポリメタクリラートが理想的である。これは、好適なコモノマーの導入により達成することができる。EP0722960では、PMMA成形材料に、exo-メチレンラクトン側鎖基を有するメタクリラートが導入されている。しかしながら該基の欠点は、親水性及びこれに伴う成形材料の吸水性である。
本発明の課題は、塊状重合又は溶液重合のためのプロセスにおいて、プロセスの反応器及び脱気装置内での腐食を招かない、従来技術に対して改善された耐熱変形性及びより高い耐候性を有する新規の成形材料を提供することである。
該課題は、二つの観点により特徴付けられる、(メタ)アクリラートベースの耐熱変形性成形材料の新規の製造法によって解決される:第一に、該方法により、少なくとも1質量%、有利には少なくとも2質量%、特に有利には少なくとも4質量%が(メタ)アクリル酸繰り返し単位から構成されている成形材料が得られる。
第一の方法において、プレポリマーは、α−ヒドロキシイソ酪酸(メタ)アクリラート又はα−ヒドロキシイソ酪酸(メタ)アクリラートのアルキルエステルの共重合により製造される。該モノマーは相応して以下の一般式を有する:
以下のものから構成されている溶液のラジカル重合(全てのパーセンテージは、出発組成物の液体分に関するものである。)
a)モノマー(50質量%)
メチルメタクリラート:42質量%
