Abstract
The present invention relates to a polymer composition capable of forming a super-hydrophobic surface which is difficult to be wetted with water and from which an adhered waterdrop can easily slide down comprising PA1 (A) a reaction product formed by a reaction of PA2 (a) a hydroxyl group-containing fluoropolymer obtained by copolymerizing a fluoroolefin, a hydroxyl group-containing vinyl monomer and another unsaturated monomer capable of coploymerizing with them, PA2 (b) an epoxy-terminated siloxane polymer represented by the formula ##STR1## wherein m is a number of 6-300 and n is a number of 0-6, at the equivalent ratio of the hydroxyl groups of the fluoropolymer (a) to the epoxy groups of the siloxane polymer (b) of 1/0.05 to 1/0.8, in the presence of PA2 (c) a sulphonic acid compound, and PA1 (B) a polyisocyanate compound, which may be blocked, or a melamine type crosslinking agent.
