ABSTRACT:
The present invention can provide a polycarbonate resin containing a structural unit represented by the following formula (1).wherein R represents one selected from an alkyl group having 1 to 9 carbon atoms, an aryl group having 6 to 12 carbon atoms, an alkenyl group having 2 to 5 carbon atoms, an alkoxy group having 1 to 5 carbon atoms, an aralkyl group having 7 to 17 carbon atoms, and halogen; and n represents the number of substituting R's on a benzene ring and is an integer of 0 to 4. Y represents an alkylene group having 1 to 4 carbon atoms; and p is an integer of 0 to 4.
