Monomer having N-acyl carbamoyl group and lactone skeleton, and polymeric compound

摘要

Disclosed is a monomer containing an N-acylcarbamoyl group and a lactone skeleton. The monomer is exemplified by Formula (1):; where R^a is selected typically from hydrogen and C₁-C₆ alkyl; R¹ is, independently in each occurrence, selected typically from halogen and optionally halogenated C₁-C₆ alkyl; “A” is selected from C₁-C₆ alkylene, oxygen, sulfur, and non-bond; m represents an integer of 0 to 8; X represents, independently in each occurrence, specific N-acylcarbamoyl; n represents an integer of 1 to 9; and Y represents a C₁-C₆ divalent organic group.
