Abstract
Official abstract text for this publication.
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 —(C a H 2a O) b — 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A (meth)acrylic-modified silicone macromonomer of the following formula (b1): wherein R 30 is a hydrogen atom or a methyl group; a is an integer of 2 to 5; b is an integer of 1 to 10; c is an integer of 2 or 3; d is an integer of 1 to 1,000; e is an integer of 1 to 80; and R 31 -R 39 are, independently from each other, a substituted or unsubstituted monovalent hydrocarbon group having no (meth)acrylic group, or an alkoxy group. 2. The (meth)acrylic-modified silicone macromonomer according to claim 1 , wherein e is an integer of 2 to 5. 3. The (meth)acrylic-modified silicone macromonomer according to claim 2 , wherein e is 2. 4. The (meth)acrylic-modified silicone macromonomer according to claim 2 or 3 , wherein a is an integer of 2 to 4, b is an integer of 1 to 10, c is 3, and d is an integer of 1 to 100. 5. The (meth)acrylic-modified silicone macromonomer according to claim 1 , wherein e is 1, and b is an integer of 1 to 10. 6. The (meth)acrylic-modified silicone macromonomer according to claim 5 , wherein a is an integer of 2 to 4, c is 3, and d is an integer of 1 to 100. 7. The (meth)acrylic-modified silicone macromonomer according to claim 1 , wherein R 31 -R 39 are, independently from each other, a methyl, phenyl, methoxy or ethoxy group. 8. The (meth)acrylic-modified silicone macromonomer according to any one of claim 1 , 2 , 3 , 5 , 6 or 7 , for use as a raw material for a polymer used in an antifouling paint. 9. The (meth)acrylic-modified silicone macromonomer according to claim 8 , wherein the antifouling paint is a marine antifouling paint. 10. An antifouling paint comprising a (meth)acrylic-(co)polymer having a monomer unit derived from polymerizing the (meth)acrylic-modified silicone macromonomer according to any one of claim 1 , 2 , 3 , 5 , 6 or 7 . 11. A marine antifouling paint comprising a (meth)acrylic-(co)polymer having a monomer unit derived from polymerizing the (meth)acrylic-modified silicone macromonomer according to any one of claim 1 , 2 , 3 , 5 , 6 or 7 .
