Stable polymer emulsion composition capable of giving a thromboresistant surface, and process for production thereof |
摘要 |
A stable polymer emulsion composition capable of giving a thromboresistant surface, said composition comprising polyurethane, a polydiorganosiloxane, and a cyclic ether, said polydiorganosiloxane being dispersed as particles having an average particle diameter of 0.1 to 50 microns in a solution of the polyurethane in the cyclic ether, and at least a part of the surfaces of said particles being crosslinked. The said composition can be prepared by dispersing a polydiorganosiloxane having a hydroxyl or acetate end group as fine particles in a solution of polyurethane in a cyclic ether to form an emulsion, and reacting the polydiorganosiloxane with a crosslinking agent to crosslink at least a part of the surfaces of the particles in the presence of 10 to 500 ppm of water.
