Abstract

See full text

The object of the present invention is to provide a silicone-based copolymer which has excellent long-term antifouling property even in a dry-wet alternate portion of a ship and the like or a portion thereof near the surface of water, is excellent also in mechanical strength and recoatability and exhibits high antifouling performance even if an antifouling agent is not added, and an antifouling coating composition containing the copolymer. The present invention provides, as the silicon-based copolymer, a metal-crosslinked organopolysiloxane-thio block vinyl copolymer [D] wherein an organopolysiloxane-thio block vinyl copolymer [C] having a carboxylic acid-containing vinyl copolymer block [A] formed from constitutional units derived from a polymerizable unsaturated carboxylic acid (a1) and constitutional units derived from at least one other polymerizable unsaturated monomer (a2) copolymerizable with the polymerizable unsaturated carboxylic acid, and a specific organopolysiloxane-thio block [B] is crosslinked with a divalent metal [M].
