PROBLEM TO BE SOLVED: To provide a symmetric hyperbranched silicone-modified polymerizable compound which has more flexibility at the branched skeleton itself than conventional one while being a highly branched structure having a siloxane chain, has good reactivity of a polymerizable functional group and is positionally and sterically symmetric.SOLUTION: There is provided a symmetric hyperbranched silicone-modified polymerizable compound which contains a compound represented by the general formula (1): [(RR)CHOCH]CHORR(1) (where, Ris a monovalent linear, branched or cyclic siloxane chain; Ris a divalent hydrocarbonylene methylene ether group represented by -CHCRR(CRR)OCH- in which R, R, Rand Rmay be the same or different and are each a hydrogen atom or may be bonded one another and are a linear, branched or cyclic hydrocarbon group having 1 to 10 carbon atoms; n1 is an integer of 0 to 10; Ris a divalent linking group; c is a 0 or 1 and Ris an unsaturated polymerizable functional group. |
