PROBLEM TO BE SOLVED: To provide a novel polymer having a ring structure in the main chain and a method for producing the same.SOLUTION: The polymer has a pyrrolidinone ring structure in the main chain. The ring structure is, for example, a structure represented by formula (1), where Ris hydrogen or -CORgroup, Ris hydrogen, methyl group, phenyl group, C2-C18 straight-chain alkyl group, or C3-C18 cycloalkyl group. Rand Rindependently represent hydrogen or methyl group.SELECTED DRAWING: Figure 1 |
