Abstract
Copolymers of a monomer of general formula <FORM:0812255/IV (a)/1> where R is hydrogen or an alkyl group of 1-4 carbon atoms, with e.g. vinyltoluene, vinyl acetate, 2 - methyl - 5 - vinyl - pyridine, methyl methacrylate, diallyl phthalate, triallyl cyanurate, N-vinylphthalimide, diallyl benzene phosphonate and styrene are described. Examples are given of (1) the co-polymerization of the di (acid maleate) of 2,21-[isopropylidene bis-(p-phenylene oxy)] diethanol with 30-60 per cent styrene; (2) the copolymerization of the di-(acid maleate) or 2,21-[isopropylidene bis-(p-phenylene oxy] dipropanol with 20-90 per cent of styrene. Both polymerizations take place in the presence of a paste of equal parts of benzoyl peroxide in tricresyl phosphate. Details are given of the physical properties of these copolymers. Specification 497,175, [Group IV], is referred to.ALSO:The invention comprises compounds of the general formula: <FORM:0812255/IV (b)/1> where R is hydrogen or an alkyl group of 1-4 carbon atoms. the compounds are prepared by reacting substantially two mols. of maleic acid or anhydride, with one mol. of the corresponding dialkanol. Examples are given of the preparation of the di-(acid maleate) of 2,21-[isopropylidene bis-(p-phenyleneoxy)] diethanol and the corresponding dipropanol. Both of these compounds may be stabilized with 100 parts per million of p-tertiary butylcatechol. Specification 497,175, [Group IV], is referred to.
