POLYMER COMPOSITION CAPABLE OF FORMING WATER-REPELLENT AND WATER DROP REMOVABLE SURFACE

摘要

PROBLEM TO BE SOLVED: To obtain a coating material capable of providing the surface of a substance with water repellency and readily dropping and removing attached water drops from the surface of the substance. ;SOLUTION: This polymer composition comprises (A) a hydroxyl-containing siloxane polymer having 50-290 mgKOH/g hydroxyl number obtained from (a) 2-40 wt.% of a siloxane macromonomer of the formula (R¹ is a 1-10C alkyl group; R² is a 1-6C bifunctional hydrocarbon group; (n) is a number of 6-300), (b) a hydroxylcontaining vinyl monomer and optionally (c) another unsaturated monomer copolymerizable with the monomers and (B) a cross-linking agent.;COPYRIGHT: (C)1999,JPO
