- SILICONE COMPOUND HAVING A RADICAL-POLYMERIZABLE GROUP AND A METHOD FOR THE PREPARATION THEREOF
-
A purpose of the present invention is to provide a polymerizable group-containing silicone compound which is liquid at room temperature, has good handling properties and compatibility with other polymerizable monomers. The present invention provides a silicone compound represented by the general formula (1) which has a structure represented by the following formula (2) or (3): wherein Rc is an alkyl group having 1 to 10 carbon atoms and Z is a radical-polymerizable group; wherein p1 and p2 are, independently of each other, positive integers such that a total number of p1 and p2 is 3 to 10, and Z is a radical-polymerizable group; and has a silicone structure bonded to the aforesaid formula (2) or (3) via a substituted or unsubstituted divalent hydrocarbon group having 1 to 10 carbon atoms. The present invention further provides a method for preparation the aforesaid silicone compound.
