PURPOSE:To obtain the titled composition giving a flexible and strong film having high oxygen-permeability and antithrombotic property and suitable as a coating agent for artificial skin, etc., by dissolving a specific vinylsilane polymer in a specific silicone oil. CONSTITUTION:The objective composition can be produced by dissolving (A) a polytriorganovinylsilane having a molecular weight of >=100,000 and composed of (A1) a recurring unit of formula I (R<1> and R<2> are methyl, ethyl, phenyl, etc.; n>=600) and containing >=50mol% said triorganovinylsilyl group in (B) a dimethyl silicone oil of formula III (a is 3-7) and/or formula IV (b is 0-5) at a weight ratio (A:B) of 0.2:99.8-70:30. |
