Abstract
A process for manufacturing high molecular weight polysiloxane copolymers by interfacial polymerization. The polysiloxanes may contain phenylmethyl siloxane blocks and dimethyl siloxane blocks, alternately polymerized together to form an (A.sub.m B.sub.n).sub.x type copolymer. The interfacial polymerization process is fast, proceeds smoothly at room temperature, and is not reversible, i.e., no cyclic siloxane species are generated. The polysiloxanes can be formed as thermoplastic elastomers suitable for use as sealants, fillers, and films.
