| 摘要 |
The present invention provides a radically curable composition comprising a radically polymerizable compound (polyallyl ester compound) containing terminal groups represented by formulae (1) and (2) (in formula (1), X1 represents a cycloalkylene group having 5 to 10 carbon atoms which may have a substituent group or an alkylene group having 2 to 10 carbon atoms which may have a substituent group) and having a structure represented by formula (3) (in the formula, R1 and R2 independently represent an alkylene group having 2 to 20 carbon atoms which may have an alkyl branch; X2 represents a cycloalkylene group having 5 to 10 carbon atoms which may have a substituent group or an alkylene group having 2 to 10 carbon atoms which may have a substituent group; and n and m represent an arbitrary positive integer); and having a number average molecular weight of 500 to 50,000. The cured product obtained by curing the radically curable composition of the present invention possesses flexibility and handleability while maintaining high transparency and heat resistance. |
