SYNTHESIS OF DUAL COPOLYMER OF METHYLHYDROSILOXANEDIME-THYLSILOXANE AND ITS GRAFT COPOLYMER WITH OLIGOOXYETHYLENE SIDE CHAIN
Abstract:
The ring opening copolymerization of D4 (octamethylcyelotetrasiloxane) and D4H (tetramethyleyelotetrasiloxane) was studied. The linear copolymers were obtained using toluene sulfonic acid as catalyst.The micro amounts of H2O presented in reaction system was found to be a chief factor influencing the average molecular weight of the product. The molecular weight of polysiloxane decreased markedly on addition of hexamethyl disiloxane (HMDS). Polysiloxanes with olgooxyethylene side chain which might be used as polymer electrolyte after eomplexing with alkali metal salts were obtained through hydrosilylation of the above mentioned polysiloxane and α-allyl oligooxyethylene ether.
