Versuchsvorschrift

Poly(trimethylene ether-tetramethylene terephthalate) was prepared as described for Example 1, with the exception that the number average molecular weight of the polytrimethylene ether glycol used was 2,390. The amounts of ingredients used were: dimethyl terephthalate, 12.52 kg; 1,4-butanediol, 14.90 kg; polytrimethylene ether glycol, 13.0 kg; tetraisopropyl titanate, 43.3 g; and ETHANOX, 80.8 g. The properties of the elastomer are reported in Table 1.
