Abstract:
A polymerizable organic composition comprising:(a) a radically polymerizable monomer represented by the following general formula,R--[--O--C(O)--O--R.sub.1 ].sub.iwherein R is a radical derived from a polyol having two or more hydroxy groups, R.sub.1 is a radical derived from an allyl or substituted allyl group and i is a whole number from 2 to 4; and(b) an additive represented by the following formula,R.sub.2 --O--(R.sub.3 O).sub.m --(CH.sub.2 CH.sub.2 O).sub.n-1 --CH.sub.2 CH.sub.2 --Xwherein R.sub.2 is a monovalent organic radical having a terminal ethylenically unsaturated group, R.sub.3 O is a divalent radical derived from an epoxide other than ethylene oxide, m is a number from 0 to 100, n is a number from 3 to 100, and X is selected from the group consisting of halide, hydroxyl, quaternary ammonium groups, the acid groups acetic acid, sulfonic acid, sulfuric acid, isethionic acid and phosphoric acid, salts of said acid groups, alkoxy groups and carboxylic acid ester groups, said additive being present in said composition in an amount at least sufficient such that a polymerizate of said composition is substantially free of tinting defects.
