Abstract
Colourless polymers of a -haloacrylic acid esters, suitable for use for optical glass, are obtained by carrying out the polymerization in the presence of water or aqueous alcohol in an amount which dissolves completely in the monomer. Preferably the monomer is saturated with water, e.g. from 0.0025-0.25 per cent. If an alcohol is also dissolved in the monomer, preferably the amount ranges from 0.0025 to 5.0 per cent of the ester. Specified a -haloacrylic compounds are methyl, ethyl, propyl, butyl, amyl, n-hexyl, octyl, lauryl, allyl, methallyl, 2-chlorallyl, crotyl, oleyl, cyclohexenyl, glycol, glyceryl, mannitol, sorbitol, phenyl, benzyl, cresyl, resorcinyl, naphthyl, phenyl ethyl, fenchyl and furfuryl a -chloracrylates. Suitable alcohols are methyl, ethyl, n-propyl, isopropyl, n-, sec.- and tert.-butyl, amyl, cyclohexyl, allyl, methallyl, crotyl, benzyl and cinnamyl alcohols. The water may be added to the purified monomer or introduced by steam distillation of the crude monomer. Polymerization may be promoted by light or oxygen containing polymerization catalysts. Specifications 518,970, 636,319, and U.S.A. Specification 2,247,790 are referred to.
