  • Publication number: 20120296051
    Abstract: Disclosed herein is a process for the production of a polysiloxane-polyorgano block copolymer. The process includes reacting a reaction mixture containing (a) an ester-functional polydiorganosiloxane and (b) a bisphenolic compound or a bisphenolic compound oligomer. This process has the advantage of yielding block copolymers with controlled block structures and avoiding the impurities that may be carried over from the conventional hydroxyaryloxy-terminated-polydiorganosiloxanes. Also disclosed are ester-functional polysiloxanes and polysiloxane-polyorgano block copolymers prepared by the process of the invention. These copolymers exhibit advantageous properties such as improved low temperature properties, improved rheological properties during molding, improved clarity, chemical, scratch resistance, and improved electrical insulation properties.
