Abstract
Polyester suitable for films, fibres or threads, results from forming, esterifying and polymerising a free flowing, homogenous dispersion of a polycarboxylic acid and polyol mixture in at least 10 times its wt. of recycled, partly esterified reaction mixture. Pref. the esterification is carried out for 0.25-1 hr. at 200-300 degrees C. and 3.4-17 atm., using 1.1-2 mol of C2-10 alkylene (ethylene) glycol per mol. of tere- or iso-phthalic acid or naphthalene dicarboxylic acid, optionally with a catalyst and/or an ether linkage inhibitor, the recycled product being 30-85% esterified.
