Abstract

A polyesterurethane elastomer comprises the reaction product of a mixture of one mol of at least one essentially linear polyester of at least one glycol containing from 4 to 10 carbon atoms and at least one dicarboxylic acid of the formula HOOC-R-COOH where R is an alkylene radical of from 2 to 8 carbon atoms or its anhydride, the polyester having an average molecular weight between 600 and 1200 and an acid number less than 10, from about 0,1 to 2,1 mols of at least one free glycol of from 4 to 10 carbon atoms, and from about 1,1 to 3,1 mols of at least one bis (phenyl isocyanate) compound, the combined average hydroxyl number molecular weight of the polyester and the free glycol being from 450 to 600, and the molar amount of the polyester and the glycol combined being substantially equivalent to the molar amount of the bis (phenyl isocyanate) compound. The products can be calendered, extruded, injection moulded, milled, or dissolved in solvents such as cyclohexanone, tetrahydrofurane, tetramethyl urea and dimethyl formamide to give cements and coating compositions. Bis (phenyl isocyanate) compounds mentioned are diphenyl methane diisocyanate, dichloro-diphenyl methane diisocyanate, dimethyl diphenyl methane diisocyanate, diphenyl dimethyl methane diisocyanate, bibenzyl diisocyanate and diphenyl ether diisocyanate. As compounding ingredients there may be added carbon black, phthalocyanine blue or green, silica, titanium oxide, calcium silicate, clay, whiting or aluminium powder.
