The present invention relates to a symmetric hyperbranched type silicone-modified polymerizable compound containing a compound represented by the following general formula (1). There can be provided a hyperbranched type silicone-modified polymerizable compound which has flexibility at the branched skeleton itself than the conventional ones, as well as 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.
[(RARB)2CHOCH2]2CHORCcRD (1)
wherein RA represents a monovalent linear, branched or cyclic siloxane chain; RB represents a divalent hydrocarbonylene methylene ether group represented by -CH2CRb1Rb2(CRb3Rb4)n1OCH2-, each of Rb1, Rb2, Rb3 and Rb4 may 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; RC represents a divalent linking group; "c" represents 0 or 1; and RD represents an unsaturated polymerizable functional group.
