Abstract: Polymerizable compositions comprising a major amount of a first allyl functional monomer, which is an aliphatic polyol (allyl carbonate) monomer, e.g., diethylene glycol bis(allyl carbonate), and a minor amount of a second allyl functional monomer, which is an aromatic polyol (allyl carbonate) monomer, e.g., 4,4′-isopropylidenediphenol bis(allyl carbonate), are described. The second allyl functional monomer is present in the polymerizable composition of the present invention in at least an amount to provide a polymerizate of the composition having (i) reduced cracking relative to a polymerizate prepared from a comparative composition that is free of the second allyl functional monomer, and (ii) a refractive index of less than 1.530. Polymerizable compositions according to the present invention may optionally comprise static dyes and/or photochromic substances.

Abstract: Describes a polymerizable organic composition comprising a polyol(allyl carbonate), e.g., diethylene glycol bis(allyl carbonate), and from 0.1 percent to 10 percent by weight, based on the total weight of the composition, of an allyl ester terminated nonaromatic polyester, e.g., diallyl 4-methyl-1,2-cyclohexanedicarboxylate oligomer with 1,4-butane diol. 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.

Abstract: The present invention provides a continuous process for making O,O-dimethyl phosphoroamidothioate. In accordance with this process, O,O-dimethyl phosphorochloridothioate is reacted with ammonia and sodium hydroxide; addition of the sodium hydroxide controls the pH of the reaction mixture. The formed reaction mixture contains an aqueous phase and an organic phase. The organic phase of the reaction mixture is separated from the aqueous phase; a second organic phase is solvent extracted from the aqueous phase; and the resultant O,O-dimethyl phosphoroamidothioate is isolated from the combined organic phases via vacuum solvent stripping. In an embodiment of the present invention, the reaction of O,O-dimethyl phosphorochloridothioate with ammonia and sodium hydroxide is carried out in the presence of a solvent.
