Title (EN) POLYMERIZABLE POLYOL(ALLYL CARBONATE) COMPOSITION
(FR) COMPOSITION POLYMERISABLE A BASE DE POLYOL(ALLYL-CARBONATE)
Abstract: front page image
(EN)Describes a polymerizable organic composition comprising a polyol(allyl carbonate), e.g., diethylene glycol bis(allyl carbonate), and from 0.1 percent to 15 percent by weight, based on the total weight of the composition, of an allyl ester terminated nonaromatic polyester, e.g., diallyl 1,4-cyclohexanedicarboxylate oligomer with propylene glycol. Polymerizates prepared from polymerizable organic compositions of the present invention have a refractive index of less than 1.53, e.g., from 1.49 to 1.50, and are substantially free of defects due to tinting failure.
(FR)L'invention concerne une composition organique polymérisable, comprenant un polyol(allyl-carbonate), par exemple, du diéthylène glycol bis(allyl-carbonate), et de 0,1 à 15 pour cent en poids, par rapport au poids total de la composition, d'un polyester non aromatique à terminaison ester allylique, par exemple un oligomère de 1,4-cyclohexanedicarboxylate diallylique avec du propylène glycol. Les polymérisats préparés à partir de compositions organiques de l'invention, ont un indice de réfraction de moins de 1,53, par exemple, de 1,49 à 1,50, et sont sensiblement exempts de défauts consécutifs à un problème de coloration.
