Zusammenfassung:	Compns. consists of a mixture of (a) linear satd. polyesters of aromatic dibasic acids and opt. up to 10 wt.-% aliphatic dibasic acids with satd. aliphatic diols; (b) undissolved solid inorg. materials pref. silicates, carbonates or oxides of Mg, Ca or Al in amount of 0.01 to 0.5 weight-%; (c) ionic copolymers of alpha-olefines and Na-salts of alpha, beta-unsatd. carboxylic acids, in amounts of 0.01 to 25 weight-, all with respect to weight of total mixture. alpha, beta-unsatd. carboxylic acids and/or esters may form part of the copolymer. Compns have high dimensional stability with very little post-moulding shrinkage.
