Abstract: 1. A process for the production of cellular or non-cellular polyurethane elastomers from organic polyisocyanates, relatively high molecular weight polyhydroxy compounds and chain extenders in the presence or absence of catalysts, blowing agents, auxiliaries and additives, wherein there are used as polyhydroxy compounds polyester polyols obtained by polycondensation of an organic dicarboxylic acid with an alcohol mixture consisting of 40 to 100% by weight, based on the alcohol mixture, of a diol mixture which in its turn consists essentially of (a) 10 to 30% by weight of 1,4-butanediol, (b) 40 to 60% by weight of 1,5-pentanediol, and (c) 15 to 35% by weight of 1,6-hexanediol, the percentages by weight being based on the total weight of the diol mixture, and 60 to 0% by weight, based on the alcohol mixture, of a dihydric alcohol selected from the group consisting of ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,8-octanediol, neopentyl glycol, 1,4-bis-(hydroxymethyl)cyclohexane, 2-methyl-1,3-propanediol, 3-methyl-1,5-pentanediol, diethylene glycol, dipropylene glycol and dibutylene glycol, or 90 to 98% by weight, based on the alcohol mixture, of the above diol mixture, and 2 to 10% by weight, based on the alcohol mixture, of a trihydric and/or tetrahydric alcohol.

Abstract: A thermoplastic polyester molding composition (I) comprises (A) 80-100 wt.% of a polyalkylene arylate having a crystallization exotherm width at half height of no more than 5 deg C and (B) 0-20 wt.% further additives. Independent claims are included for (i) optical fiber sheathing and cable sheathing prepared from (I) and (ii) a process for the production of (I) by (a) esterification and/or ester exchange of an aromatic dicarboxylic acid, ester and/or ester forming derivative with a molar excess of a dihydroxy compound; (b) precondensing the resulting product followed by (c) polycondensation to a viscosity number of 158 ml/g whereby (a) and (b) are carried out in at least 2 temperature zones and optionally adding (B) before cooling of the melt before or after step (c).
