UV ABSORBING COMPLEX POLYESTER POLYMERS, COMPOSITIONS CONTAINING UV ABSORBING COMPLEX POLYESTER POLYMERS, AND RELATED METHODS

摘要

PROBLEM TO BE SOLVED: To provide a UV absorbing complex polyol polyester polymer.SOLUTION: The invention provides linear UV absorbing complex polyol polyester polymers represented by formula (XI), where the polymer of formula (XI) is a linear polyester polyol polymer. (R3 is independently selected from a UV absorbing moiety; R4 and R5 are each independently a substituted/unsubstituted, saturated/unsaturated C2-54 hydrocarbon group having and 0 to 30 ether linkages; and n is an integer from 2 to 1000.)SELECTED DRAWING: None
