    • Provided is a method of preparing a photochromic polymeric article including: (a) providing a fluid polymerizable composition of: at least one monomer; a first initiator for inducing polymerization of the monomer at a first temperature; and a second initiator for inducing further polymerization at a second temperature higher than the first temperature; (b) heating the polymerizable composition to at least the first temperature whereby the first initiator induces polymerization of the monomer at the first temperature to produce a polymerizate; (c) heating the polymerizate of (b) to at least the second temperature to further polymerize the polymerizate; and (d) contacting the polymerizate with an organic photochromic substance to incorporate the organic photochromic substance into the polymerizate. Photochromic articles prepared by the method are also provided.
    • 提供一种制备光致变色聚合物制品的方法,包括:(a)提供一种流体可聚合组合物:至少一种单体; 在第一温度下引发单体聚合的第一引发剂; 和在高于第一温度的第二温度下诱导进一步聚合的第二引发剂; (b)将可聚合组合物加热到至少第一温度,由此第一引发剂在第一温度下引发单体的聚合以产生聚合物; (c)将(b)的聚合物加热至至少第二温度以进一步聚合聚合物; 和(d)使聚合物与有机光致变色物质接触,以将有机光致变色物质并入聚合物中。 还提供了通过该方法制备的光致变色制品。
