Patent ID: 7056988

Claim:
A polymer compound comprising a cyclic structure represented by the following general formula (1): wherein X represents a group selected from the group consisting of an alkylene group, an arylene group, an arylalkylene group, an alkylarylene group, halogenated alkylene group and halogenated arylene group; Y represents a group selected from the group consisting of an alkylene group, an arylene group, an arylalkylene group, an alkylarylene group, a halogenated alkylene group and a halogenated arylene group; Z represents a connecting group derived from an alkylene group having from 1 to 20 carbon atoms, an ester group, a urethane group, an amide group or an ether group, which connects the Y of the cyclic structure to a group represented by Y belonging to at least a second cyclic structure of general formula (1); m represents 0 or an integer of 1 or more; and n represents an integer of 2 or more, provided that m is independently selected for each respective repeating unit within the cyclic structure, and a total number of connecting groups represented by Z in the cyclic structure is 1 or more.
