Abstract
Rigid polymerized halide compositions comprise 84 to 98 parts (weight) of a rigid polymer of halide containing a <FORM:0844240/IV(a)/1> group and only carbon, hydrogen and halogen atoms and 2 to 16 parts of a rubbery reaction product of an organic di-or tri-isocyanate and a hydroxy terminated polyol having a molecular weight of at least 500. Polymerized halides specified are polyvinyl chloride, bromide, fluoride and iodide and copolymers e.g. vinyl chloride/vinyl acetate. The isocyanates may be aromatic and/or alphatic diisocyanates e.g. p.p1.-diisocyanato diphenyl methane; 2, 4-tolylene di-isocyanate; napthalene-1, 5-diisocyanate; and hexamethylene diisocyanate. The polyols have substantially linear molecular chains having only carbon to carbon or carbon to oxygen linkages and preferably contain only C, H and O atoms. They may contain some double bond unsaturation but are preferably aliphatically saturated. Examples of suitable polyols are dihydroxy polyesters and polyethers preferably having a molecular weight of 2,000 to 4,000 e.g. poly (ethylene-propylene) adipate and polytetramethylene ether glycol The preferred polyurethanes are flexible or rigid polyurethanes obtained by using polyesters of polyethers of the cross-linking-type or a cross-linking agent such as trimethylol propane may also be used. Examples describe(i) the preparation of a polyester from the ethylene glycol, propylene glycol, and adipic acid; (ii) the preparation of a polyurethane from the product of (i) and p, p1-diisocyanato-diphenyl methane; and (iii) compositions consisting of PVC and a polyurethane derived from the ester of (i) or polytetramethylene ether glycol and p, p1-diisocyanato-diphenyl methane or 2, 4-tolylene diisocyanate. Specification 694,978 is referred to.
