<p>PURPOSE:To obtain the title copolymer useful as films, tubes, etc., having excellent slipperiness, mold release characteristics, high oxygen permeability, water repellency, etc., by reacting a polydialkylsiloxane containing Si-H at both ends with an alpha-olefin in the presence of a hydrosilylating catalyst. CONSTITUTION:(A) A polydialkylsiloxane containing Si-H at both ends shown by formula I (R is monofunctional hydrocarbon; a is 1-1,000) is reacted with (B) an alpha-olefin (e.g., 1-pentene) shown by formula II (b is 5-100) in the presence of a hydrosilylating catalyst (e.g., chloroplatinic acid) to give the aimed linear copolymer shown by formula III.</p> |
