Polymerisable polyol (allyl carbonate) compositions

描述了可聚合的组合物，该组合物包括多元醇(烯丙基碳酸酯)单体，例如，二甘醇双(烯丙基碳酸酯)单体，和由通式(II)表示的添加剂，其中R#-[2]和R#-[6]各自独立地选自氢，C#-[1]-C#-[20]直链或支链烷基，在环中具有5-7个碳原子的环烷基，芳基，C#-[2]-C#-[20]直链或支链的烷酰基，在环中具有5-7个碳原子的环烷酰基，和芳酰基，R#-[2]和R#-[6]各自不含自由基可聚合的烯属不饱和基团；R#-[3]O和R#-[5]O是相同的或不同的；R#-[4]O不同于R#-[3]O和R#-[5]O中的每一个；R#-[3]O、R#-[4]O和R#-[5]O各自独立地是环氧基的二价残基；x和z各自独立地是0-200的数，前提条件是x和z的总和大于0，和y是3-200的数。添加剂存在于本发明的组合物中，存在量至少足以使得组合物的聚合产物基本上不含着色缺陷，如蕨类和月亮。∴ A polymerizable composition is described, which composition comprises a polyol(allyl carbonate) monomer, e.g., diethylene glycol bis(allyl carbonate) monomer, and an additive represented by the general formula,wherein R2 and R6 are each selected independently from hydrogen, C1-C20 linear or branched alkyl, cycloalkyl having from 5 to 7 carbon atoms in the cyclic ring, aryl, C2-C20 linear or branched alkanoyl, cycloalkanoyl having from 5 to 7 carbon atoms in the cyclic ring and aroyl, R2 and R6 each being free of radically polymerizable ethylenically unsaturated groups; R3O and R5O are the same or different; R4O is different than each of R3O and R5O; R3O, R4O and R5O are each independently a divalent residue of an epoxide; x and z are each independently a number from 0 to 200, provided that the sum of x and z is greater than zero; and y is a number from 3 to 200. The additive is present in the composition of the present invention in an amount at least sufficient such that a polymerizate of the composition is substantially free of tinting defects, such as ferns and moons.
