Abstract: 1,229,870. Cross-linked tetramethylene ether polymers; graft polymers. QUAKER OATS CO. 21 May, 1968 [16 June, 1967], No. 24253/68. Headings C3G and C3R. Cross-linked tetramethylene ether polymers have chains of molecular wieght from 300 to 3000 linked together by a direct carbon-tocarbon bond. The polymers may be homopolymers of tetrahydrofuran or they may be grafted with unsaturated compounds of the formula CH 2 =CR<SP>1</SP>E where R<SP>1</SP> is H or CH 3  and E is an electron sink to provide pendant polymer chains. Examples of such compounds are styrene, acrylonitrile, vinyl chloride and acetate and butyl acrylate and methacrylate. The cross-linking is effected by heating at 80‹ to 230‹ C. with a free radical generator of the formula POOP<SP>1</SP> where P and P<SP>1</SP> are substituents in which the structure adjacent to the peroxy group is aroyl or a tertiary carbon to which is attached 2-methyl groups. Suitable peroxides are dicumyl peroxide, di-t-butyl peroxide, tbutyl perbenzoate, t-butyl-1,1,3,3-tetramethylbutyl peroxide and 2,5-dimethyl-2,5-di(t-butyl peroxy)hexane. The THF polymers may be terminated by OH, halogen, unsaturated or ester groups. The hydroxy-terminated products may be reacted with diisocyanates to form polyurethanes and made into films. Specification 1,001,345 is referred to.
