Abstract

An acetone-soluble interpolymer of a styrene having an unsubstituted vinyl radical, a diallylic fumarate and an allylic alcohol is heated at, for example 70-125 DEG C., so as to liberate the allylic alcohol which is removed continuously or intermittently, the process being carried out till the interpolymer on standing for 7 days at 70 DEG C. shows the presence of not more than 0.4 per cent of free allylic alcohol. By the term " allylic " is meant the group CH2 = C(X)-CH2-, where X is hydrogen, methyl or chlorine. Styrenes specified are styrene, p-methyl, -ethyl and -chloro styrenes. An inert liquid solvent such as xylene, solvent naphtha, diacetone alcohol, carbon tetrachloride, cyclohexane, benzene and toluene, and inhibitors such as guaiacol or hydroquinone may be present, and further solvent may be added during the process, which may be effected at reduced pressure. The resulting interpolymer may be cross-linked with methyl acrylate, allyl acrylate or vinyl acetate. Specification 606,080 is referred to.
