Abstract : The patent describes a polymer composition of arylene modified siloxazanes incorporating cyclodisilazane structures prepared by the condensation of arylenedisilanols and cyclodisilazane derivatives. Gelling of the product polymer is prevented by treating the initial solution of reactants with a silylating agent. The product polymers which exhibit good elastomeric properties as well as thermal stability can be compounded into rubbers by cross-linking the product polymer through use of a peroxide catalyst and preferably with the addition of a suitable filler.
