| titleOfInvention | Polyol(allyl carbonate) composition |
| abstract | Polyol(allyl carbonate) compositions and polymerizates thereof that have an enhanced resistance to yellowing on exposure to external heating are described. In particular, a polyol(allyl carbonate) composition comprising (a) from about 55 to about 90 weight precent of a polyol(allyl carbonate), e.g., diethylene glycol bis(allyl carbonate), from about 10 to about 40 weight percent of aliphatic polyurethan having terminal ethylenic unsaturation, e.g., an aliphatic polyesterurethan diacrylate, and from about 0 to about 5 weight percent of a difunctional monomer selected from the group consisting of allyl methacrylate and allyl acrylate and (b) from about 0.01 to about 0.5 weight percent of a dialkyl pyrocarbonate, e.g., diethyl pyrocarbonate, based on the weight of the polymerizable reactants is described. Polymerizates of such polyol(allyl carbonate) compositions have an enhanced resistance to yellowing when heated at elevated temperatures, e.g., 130°C. |
