TEMPORARILY CROSSLINKED POLYESTER POLYMERS |
摘要 |
A process for increasing the pill resistance of a polyester polymer wherein the polyester polymer is produced by polymerizing a polymerization mixture comprising (a) a carbonyl compound or an oligomer of the carbonyl compound and (b) a glycol. The process comprises contacting the polymerization mixture with a cross-linker comprising (RO)mSi(X)nZn, wherein: R is hydrogen, a hydrocarbon, or a hydrocarbon oxygen; X is a hydrocarbon or a hydrocarbon oxygen; Z is a hydrophilic group; m is 1 to 3; n is 1 to 3; and p is 1 to 30.
