ABSTRACT:
The present invention relates to a novel organopolysiloxane-modified polyester and a method for the preparation thereof. The organopolysiloxane-modified polyester polymer comprises a polyester segment having a number average molecular weight of 300 to 15,000, a silicon-bonded hydrolyzable group-free organopolysiloxane segment, and a silicon-bonded hydrolyzable group-containing silicone segment. The compositions of the present invention are characterized by their ability to cure at room temperature in the presence of a condensation reaction-accelerating catalyst.
