Abstract: APPARATUS AND PROCESS FOR CONTINUOUS POLYMERIZATION OF POLYAMIDEDS TO PRODUCE A POLYMER WHEREIN THE REQUIRED VISCOSITY CAN BE OBTAINED MUCH MORE RAPIDLY AND THE EXTENT OF POLYMERIZATION FAR GREATER THAN HERETOFORE POSSIBLE BY USE OF A VACUUM DEMOISTURIZING COLUMN WITHIN THE POLYMERIZATION TRAIN WHEREIN THE PRE-POLYMER IS CONVERTED TO POLYAMIDE OF HIGHER MOLECULAR WEIGHT IN A SHORT PERIOD OF TIME BY EXPOSING AT LEAST ABOUT 0.2 SQUARE FOOT OF PRE-POLYMER PER POUND THEREOF TO A TEMPERATURE OF BETWEEN ABOUT 230*C. AND ABOUT 300*C. AT PRESSURES OF LESS THAN ABOUT 500 MM. HG. THE APPARATUS AND PROCESS YIELDS EVEN GREATER EFFICIENCIES WHEN USED IN CONJUNCTION WITH POLYAMIDATION CATALYSTS.

Abstract: Spinnable compositions for yarn manufacture consist of (a) a fibre-forming polyamide, (b) up to 50% wt. fibre-forming polyester dispersed in (a), and (c) 0.05-0.6% wt. saturated acyl compd. having a C12-22 straight carbon chain, and a m.p. of more than 100 deg.C, as spinning assistant. Compd. (c) is pref. an alkali or alkaline earth metal salt of an aliphatic carboxylic acid. Sodium stearate, sodium palmitate or calcium stearate are particularly pref. as spinning assistants. Addn. of compd. (c) gives spinnable compositions for yarn prodn. baving a reduced tendency to block the orifices in the spinning plate. The composition is suitably based on mixtures of polyethylene terephthalate with polycaprolactam and/or polyhexamethyleneadipamide.
