Title:
FLUOROSILICONE POLYMER AND CURABLE FLUOROSILCONE POLYMER COMPOSITION
Document Type and Number:
Japanese Patent JPH05301963
Kind Code:
A
Abstract:
PURPOSE:To obtain the subject polymer, composed of a specific structural unit, having a high curing rate and a low surface tension, excellent in releasability, water and oil repellency and useful as a mold releasing agent, etc., for a silicone pressure-sensitive adhesive. CONSTITUTION:The objective polymer is expressed by the formula {T is trialkylsiloxy or hydroxyl group; R is monovalent hydrocarbon; Q is 4-8C alkenyl; (a) is >=4; (x) is >=1; (y) is 0 or >=1; (z) is >=1; (x+y+z) is >=50; [x/(x+y+z)] is >=0.25; [z/(x+y+z)] is <=0.1}. Furthermore, this polymer is mixed with (A) an organohydrogenpolysiloxane, having >=2 hydrogen atoms bound to silicon atoms on the average based on one molecule and the hydrogen atoms bound to the separate silicon atoms, (B) a hydrosilylating reactional catalyst such as chloroplatinic acid and (C) an inhibitor of the hydrosilylating reactional catalyst such as 3-methyl-1-butyn-3-ol to afford the objective curable fluorosilicone polymer composition.
