树脂组合物和由其形成的光学部件
摘要：
本发明涉及树脂组合物和由其形成的光学部件。本发明提供即使在高温和高剪切下加工，气体产生和发尘也少，无损环状烯烃系树脂本来具有的高透明性、低着色和高耐热性的树脂组合物。所述树脂组合物的特征在于，含有环状烯烃系树脂(A)和在1分子内具有2个以上下述式(2)所示基团的酚系化合物(B)。(式(2)中，R14a和R14b各自独立地表示氢原子、或者直链状或支链状的碳原子数1～10的烃基，R15和R16各自独立地表示碳原子数1～10的烃基，X表示亚甲基或碳原子数2～10的亚烷基)。
摘要（英）：

The invention relates to a resin composition and optical parts comprising the same. The invention provides a resin composition whose nondestructive ring shape ethylene series resin has high transparency, low coloring and high hear resistance even if the resin composition is processed under high temperature and high shearing, and the generated gas and dust is little. The resin composition comprises ring shape ethylene series resins (A) and phenol compounds (B) possessing over two groups shown in the following formula (2) in one molecule. In the formula (2), R14a and R14b respectively represent hydrogen atoms or straight chain type or branch chain type alkyl with 1-10 carbon atoms, and R15 and R16 respectively represent alkyl with 1-10 carbon atoms, and X represents methylene or alkylene with 2-10 carbon atoms.
