Abstract
A symmetric hyperbranched type silicone-modified polymerizable compound contains a compound represented by the following general formula (1). A hyperbranched type silicone-modified polymerizable compound has flexibility at the branched skeleton itself than the conventional ones, and reactivity of a polymerizable functional group is good and it is positionally and sterically symmetric, while it has a highly branched structure having siloxane chains.[(RR)CHOCH]CHORR  (1)Rrepresents a monovalent linear, branched or cyclic siloxane chain; Rrepresents a divalent hydrocarbonylene methylene ether group represented by —CHCRR(CRR)OCH—, each of R, R, Rand Rmay be the same or different from each other and represents a hydrogen atom or a linear, branched or cyclic hydrocarbon group having 1 to 10 carbon atoms which may be bonded to each other, 'n1' represents an integer selected from 0 to 10; R, a divalent linking group; 'c', 0 or 1; and R, an unsaturated polymerizable functional group.
