STYRENE COPOLYMER AND PROCESS FOR PRODUCING SAID COPOLYMER |
摘要 |
Styrene copolymers having a repeating unit (I) represented by the general formula: <CHEM> and a repeating unit (II) represented by the general formula: <CHEM> (wherein all the symbols are as defined in the appended claims), and having the stereoregularity that is mainly syndiotactic, and cross-linked styrene copolymers obtained by cross-linking the above styrene copolymers. The styrene copolymers are reactive resins (heat-sensitive resins and radiation-sensitive resins) and are excellent in heat resistance and chemical resistance. The cross-linked styrene copolymers are excellent in heat resistance, chemical resistance and mechanical strength. |
