ABSTRACT:
There is disclosed an organopolysiloxane having a molecular weight of 200 to 100,000 which contains at least one silicon-bonded, chloroformyl group-containing organic group, said organopolysiloxane being prepared by reacting (I) the corresponding organopolysiloxane which contains at least one silicon-bonded, triorganosiloxycarbonyl group-containing organic group; and (II) an inorganic halide, such as thionyl chloride. By virtue of its highly reactive chloroformyl group, the organopolysiloxane of the invention find utility as modifiers for polyamide resins, polyester resins, and the like.
