Resumo

α-メチルスチレン (MS) とアクリロニトリル (AN) のコポリマー鎖にN-フェニルマレイミド (PMI) またはN-P-クロロフェニルマレイミド (CPMI) を3～17mol%導入した5種のMS-AN-PMI及びMS-AN-CPMIターポリマーをそれぞれ合成した. 得られたターポリマーの熱的性質に及ぼすPMI及びCPMI組成の影響を検討した結果, PMI及びCPMI組成の増加に従ってガラス転移温度 (Tg), 軟化温度 (Tsoft), 及び熱分解開始温度 (Td) が著しく上昇することを認めた. これより耐熱性に優れる環構造のマレイミド単位をMS-ANコポリマー鎖に適量導入することによりコポリマーの熱的性質を必要に応じて改善できることが明らかとなった.
