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 substituted acetylene polymer in a specific silicone oil. CONSTITUTION:The objective composition can be produced by dissolving (A) a substituted polyacetylene having a molecular weight of >=100,000 and composed of (A1) 100-70mol% structural unit of formula I (R<1> is 1-4C univalent hydrocarbon group; n is 1 or 2) and (A2) 0-30mol% structural unit of formula II (R<2>-R<4> are 1-4C univalent hydrocarbon group) in (B) one or more kinds of dimethyl silicone oils of formula III (a is 3-7) and/or formula IV (b is 0-5) (e.g. hexamethylcyclotrisiloxane) at a weight ratio (A:B) of 0.1:99.9-50:50. |
