Uv absorbing complex polyester polymers, compositions containing uv absorbing complex polyester polymers, and related methods |
abstract |
The present invention relates to a process for the preparation of (i) an esterification of a polyol and a dianhydride under ring opening conditions of anhydride, which forms a polyester polymer having two or more carboxyl groups and two or more hydroxyl groups; And (ii) a UV-absorbing composite polyol polyester polymer which is a product of a process comprising the reaction of a polyester polymer with at least one carboxyl group and at least one terminal hydroxyl group and an epoxide comprising a UV absorbing moiety and having a functional group . The crosslinked UV-absorbing composite polyol polyester polymer is a random copolymerization ester reaction product and / or an esterification product. |
