Durch Polysiloxane modifizierte Polyester und Verfahren zu deren Herstellung

摘要

The present invention relates to a novel organopolysiloxane-modified polyester and a preparatory method for the same. The oganopolysiloxane-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 curable at room temperature in the presence of a condensation-reaction catalyst.
