  In one aspect, the present disclosure encompasses polymerization systems for the copolymerization of CO2 and epoxides comprising 1) a catalyst including a metal coordination compound having a permanent ligand set and at least one ligand that is a polymerization initiator, and 2) a chain transfer agent having two or more sites that can initiate polymerization. In a second aspect, the present disclosure encompasses methods for the synthesis of polycarbonate polyols using the inventive polymerization systems. In a third aspect, the present disclosure encompasses polycarbonate polyol compositions characterized in that the polymer chains have a high percentage of —OH end groups and a high percentage of carbonate linkages. The compositions are further characterized in that they contain polymer chains having an embedded polyfunctional moiety linked to a plurality of individual polycarbonate chains.

  Described are photochromic organic resin compositions and the impact resistant polymerizates and coating compositions made therefrom. The organic resin composition comprises the reaction product of at least one polyol having greater than 1.0 hydroxyl groups; at least one polyisocyanate having greater than 1.0 isocyanato groups; and at least one polyamine curing agent having greater than 1.0 amino groups. The polymerizates are made photochromic either by the addition of organic photochromic compounds to the reactants used to form the polymerizate or by methods that imbibe or transfer the photochromic compounds into the polymerizate. Optically clear photochromic and impact resistant articles such as ophthalmic lenses and articles having photochromic coatings prepared from the photochromic organic resin compositions are also described.

  本发明描述了光致变色有机树脂组合物以及由其制成的抗冲击聚合体和涂料组合物。有机树脂组合物包括至少一种具有大于 1.0 个羟基的多元醇、至少一种具有大于 1.0 个异氰酸基的多异氰酸酯和至少一种具有大于 1.0 个氨基的多胺固化剂的反应产物。要使聚合体具有光致变色性，可在用于形成聚合体的反应物中加入有机光致变色化合物，或采用将光致变色化合物吸入或转移到聚合体中的方法。此外，还介绍了用光致变色有机树脂组合物制备的具有透明光致变色和抗冲击性能的物品，如眼科镜片和具有光致变色涂层的物品。
