NOVEL FLUORINE COMPOUND, PROCESS FOR PRODUCING THE SAME, AND POLYMER THEREOF

摘要

A novel polymer useful as an optical resin material excellent in heat resistance, a novel monomer for obtaining the polymer, etc., are provided. A fluorinated diene represented by CF2=CF(CF2)nC(CF3)ROCF=CF2 (wherein R is a fluorine atom or a trifluoromethyl group, and n is an integer of from 1 to 3), and a polymer thereof.
