ABSTRACT:
This invention provides polyorganooxothiazenes exhibiting levels of molecular weight and properties not heretofore achieved by similar polymers reported in the prior art. The sulfonimidates that are condensed to form the polymers are prepared using a novel reaction between an N-triorganosilylsulfonamide and a triorganodihalophosphorane to form the corresponding N-triorganosilylsulfonimidoyl halide that is subsequently reacted with a fluorinated alcohol or phenol to form the N-triorgano-silylsulfonimidate.
