| abstract | 1312923 Unsaturated polyesters ARMSTRONG CORK CO 24 March 1970 [26 March 1969] 14124/70 Heading C3R An unsaturated condensation polyester comprises the condensation product of (a) 10-40 mol per cent of tetrahydrophthalic acid, tetrahydrophthalic anhydride or mixtures thereof, (b) 10-40 mol per cent of iso-, ortho- or terephthalic acid (or dialkyl esters thereof or phthalic anhydride) and (c) a glycol member having a No. Av. M. Wt. of 115-300, being a polyether diol of maximum M. Wt. of 2000, mixtures of polyether diols or copolyether diols of maximum No. Av. M. Wt. 2000 and mixtures thereof with up to 90 wt. per cent of an alkylene glycol HO-R-OH or mixtures thereof where R is an alkylene group of 2-6 C atoms. The polyester may be chain extended by reaction with up to 1À0 equivalent of an organic diisocyanate per equivalent of acid to give resins of minimum M. Wt. of 20,000 which are sulphur cured. In the examples the diols used are: polyoxyethylene diol-400, ethylene glycol, neopentyl glycol, tetraethylene glycol, polyoxypropylene diol- 1025, copoly(oxypropylene-oxyethylene) diol- 2000 and poly(oxytetramethylene)diol-1000. The polyesters are chain extended with 2,4- toluene diisocyanate and sulphur cured using conventional recipes. |
