Abstract
The present invention aims to provide a (meth)acrylic-modified silicone macromonomer, which may be used as a raw material for a (meth)acrylic copolymer capable of forming a coating having excellent antifouling properties and surface smoothness. A (meth)acrylic-modified silicone macromonomer of formula (b1) is provided, which has 1 to 80 branches attached to a linear polysiloxane backbone and the branch has a (poly)oxyalkylene structure of the formula —(CHO)— and a (meth)acryloyl group at a terminal. The (meth)acrylic-modified silicone macromonomer is a raw material for a polymer used in an antifouling paint.
