Abstract

Polyurethanes by reacting an organic polyisocyanate with a hydroxyl group containing polyester obtained by reacting adipic acid with a mixture of glycols containing 60-75% by weight of hexane 1, 6 diol and a total of from 25-40% by weight of one or both of butane 2, 3 diol and 2, 2 dimethyl-propane 1, 3 diol. Chain extenders e.g. water, glycols, diamines, aminoalcohols, hydrazides may be reacted simultaneously with, or after the polyester-isocyanate reaction. Free radical forming substances may be added to the polymer and heated to at least 130 DEG C. to vulcanize. Many organic diisocyanates are specified and also many suitable chain extending agents. Free radical forming substances mentioned are dicumyl peroxide, tertiary butyl dicumyl peroxide, 2, 5 di (tertiary butyl-peroxy)-2, 5 dimethyl hexane and azoisobutyric acid dinitrile which are preferably used in amount 0.5-10% by weight. A thermoplastic product is obtained by using an NCO to OH ratio within the range 0.9 to 1.2. Fillers and pigments e.g. carbon black, SiO2, TiO2 and glass fibres may be added. In example (1) butane 1, 4 diol was added to a dehydrated polyester obtained from adipic acid, hexane 1, 6 diol and butane 2, 3 diol, followed by diphenylmethane 4,41 diisocyanate and the mixture stirred at 130 DEG C. and heated for 24 hours at 100 DEG C. To the product was added carbon black, stearic acid, and dicumyl peroxide and heated to 151 DEG C. to vulcanize. Example (2) used 2, 2 dimethyl propane 1, 3 diol and hexane 1, 6 diol in the preparation of the polyester.
