<P>PROBLEM TO BE SOLVED: To provide a novel (meth)acrylic group-containing organopolysiloxane which is excellent in reactivity with an acrylic monomer, is produced by using a general-purpose raw material and an easy production method and in which an Si atom is modified with a hydrocarbon group having a plurality of acrylic groups; to provide a production method of the novel (meth)acrylic group-containing organopolysiloxane; and to provide a polymer of the above polysiloxane with a radical polymerizable monomer. <P>SOLUTION: The (meth)acrylic group-containing organopolysiloxane is expressed by formula (I). In the formula, R represents a monovalent hydrocarbon group or alkoxy group containing no (meth)acrylic group; Q represents A and/or X and at least one of Q is A; A is -R<SP POS="POST">1</SP>-CONH-C(R<SP POS="POST">2</SP>)[CH<SB POS="POST">2</SB>-O-CO-CH=CH<SB POS="POST">2</SB>]<SB POS="POST">2</SB>or -R<SP POS="POST">1</SP>-CONH-C(R<SP POS="POST">2</SP>)[CH<SB POS="POST">2</SB>-O-CO-C(CH<SB POS="POST">3</SB>)=CH<SB POS="POST">2</SB>]<SB POS="POST">2</SB>, where R<SP POS="POST">1</SP>represents a divalent organic group and R<SP POS="POST">2</SP>represents a monovalent hydrocarbon group or alkoxy group containing no (meth)acrylic group; X represents R or an active hydrogen-containing monovalent organic group containing no (meth)acrylic group; and a and b satisfy 0≤a≤1,000 and 0≤b≤100. <P>COPYRIGHT: (C)2013,JPO&INPIT |
