Title:
CROSSLINKED POLYESTER COPOLYMERS
Document Type and Number:
WIPO Patent Application WO2004072140
Kind Code:
A3
Abstract:
A glycol-organosilane composition and a process for producing the composition are disclosed. The composition comprises or is produced by combining (a) a glycol and (b) an organosilane. This composition is preferably substantially soluble in glycol and water. Also disclosed is a crosslinked polyester copolymer composition and a process to produce the composition. The composition comprises repeat units derived from (a) a carbonyl compound or its oligomer, (b) a glycol, (c) a crosslinker, and (d) optionally a comonomer. The crosslinker can be the glycol-organosilane, a carbonyl compound containing 3 or more carboxyl groups, or an alcohol containing 3 or more hydroxyl groups. The comonomer is a dicarboxylic compound, a diol compound, or a carbonyl alcohol. The polyester composition can be used to increase the rate of polymerization, to increase pilling resistance and strength of polyester, to decrease crystallization rate and improve object forming process such as fibers and containers.
