Abstract : The invention relates to siloxane and siloxazane polymers which contain vinyl groups. Polymer compositions are prepared by the polycondensation of an arylenedisilanol, a cyclic siloxazane compound or an N,N'-aminosilyl derivative thereof, and a vinyl-substituted arylenedisilanol. The polymer products are elastomeric and can be readily cured with conventional peroxide curing agents. Furthermore, the rubbery polymers exhibit a high degree of thermal stability and possess outstanding physical properties. The products can be formed into films, thereby rendering them particularly useful as protective coatings.
