Fluorinated acrylate derivatives having carbonate groups and polymerizable composition comprising same

Abstract

A polymerizable composition comprising a novel carbonate group-containing acrylate derivative of formula (I) of the present invention is used to prepare a polymer film or molded product having improved compatibility with dyes, high adhesivity to a substrate, low optical loss and low birefringence: 1 wherein: n is an integer of 1 to 4; R1 is hydrogen or C1-3 alkyl; R2 is —(CH2)aO— or —(CH2CH2O)b— (a is an integer of 1 to 20, and b is an integer of 2 to 20); R3 is an optional substituent selected from the group consisting of —CH2—, —C6H4— and —C6F4—; and R4 is C1-10 perfluoroalkyl when n=1; when n=2, a bridging group comprising at least one linking moiety selected from the group consisting of C1-3 perfluoroalkylene, C1-3 perfluoroalkyleneoxy and —CF2CFCl—; or when n=3 or 4, a bridging group comprising 2 and said linking moiety.
