    • Describes polymerizable organic compositions of from about 30 to 95 weight percent of a first monomer component which is an alkoxylated diol, e.g., alkoxylated bisphenol, having acrylate or methacrylate groups, i.e., dimethacrylate of bisphenol A having an average of 1 to 4 ethoxy units, and from about 5 to 70 weight percent of a second monomer component which is an alkoxylated diol, e.g., alkoxylated bisphenol, having acrylate or methacrylate groups, i.e., dimethacrylate of bisphenol A having 25 to 70 ethoxy units. Optionally there may also be present from about 0 to 65 weight percent of at least one monomer component which is selected from: (i) a monoethylenically unsaturated monomer that is polymerizable by free radical initiation; (ii) a bis�(meth)acryloyl-terminated!polyethylene glycol monomer; and (iii) a monomer having at least three terminal ethylenically-unsaturated groups. Substantially completely cured polymerizates prepared from such compositions may be used to prepare photochromic articles, e.g., lenses, by incorporating a photochromic substance, e.g., by thermal transfer, into the polymerizate.
    • 描述了约30至95重量%的第一单体组分(其为烷氧基化二醇)的可聚合有机组合物,例如具有丙烯酸酯或甲基丙烯酸酯基团的烷氧基化双酚,即具有平均1至4个乙氧基单元的双酚A的二甲基丙烯酸酯, 和约5至70重量%的第二单体组分,其为烷氧基化二醇,例如具有丙烯酸酯或甲基丙烯酸酯基团的烷氧基化双酚,即具有25至70个乙氧基单元的双酚A的二甲基丙烯酸酯。 任选地,还可以存在约0至65重量%的至少一种单体组分,其选自:(i)可通过自由基引发聚合的单烯属不饱和单体; (ii)双((甲基)丙烯酰基封端的]聚乙二醇单体; 和(iii)具有至少三个末端烯属不饱和基团的单体。 通过将这种组合物制备的基本上完全固化的聚合物可以用于通过将光致变色物质例如通过热转移引入到聚合物中来制备光致变色制品,例如镜片。

    • Describes a polymerizable composition of (a) a first allyl functional monomer, which is selected such that a substantially completely cured polymerizate of the first allyl functional monomer has a 15 second Barcol 934 hardness of at least 40, and (b) a second allyl functional monomer selected from polyether diol bis(allyl carbonate), polylactone diol bis(allyl carbonate) and mixtures thereof. The second allyl functional monomer is present in the composition in an amount to provide a substantially completely cured polymerizate having: (i) improved organic photochromic substance incorporation relative to a substantially completely cured polymerizate of the composition free of monomer (b); and (ii) heat distortion temperature of at least 40° C.
    • 描述了(a)第一烯丙基官能单体的可聚合组合物,其被选择为使得第一烯丙基官能单体的基本上完全固化的聚合物具有至少40的15秒钟Barcol 934硬度,和(b)第二烯丙基官能团单体 选自聚醚二醇双(烯丙基碳酸酯),聚内酯二醇二(碳酸烯丙酯)及其混合物的单体。 第二烯丙基官能单体存在于组合物中,其量提供基本上完全固化的聚合物,其具有:(i)相对于不含单体(b)的组合物的基本上完全固化的聚合物改进的有机光致变色物质的掺入; 和(ii)至少40℃的热变形温度
