Abstract: Continuous production of copolyamides (I) based on a lactam (A), a diamine (B) and a dicarboxylic acid (C) comprises a three step reaction sequence to form a polymer containing up to 10 wt.% material extractable by hot water at 95 deg C comprising (A), (B) or (C). The polymer is extracted with water to form the copolyamide product (I). A process for the continuous production of copolyamides (I) based on a lactam (A), a diamine (B) and a dicarboxylic acid (C) comprises conversion of a mixture comprising diamine (B), dicarboxylic acid (C) and water in a first reaction zone at 1.3x10 -2.5x10 Pa to a degree of conversion of at least 80 % (with respect to molar quantities of (B) and (C)) to form a polymer (D) at a temperature above the m.pt. of (D) and conversion of a mixture comprising lactam (A) and water in a second reaction zone at 5x10 -40x10 Pa to a degree of conversion of at least 80 % (with respect to molar quantity of (A)) to form a polymer (E) at above the m.pt. of (E) followed by reaction of (D) and (E) in a third reaction zone at 1x10 -1.5x10 to form a polymer (F) at above the m.pt. of (F) whereby (F) contains up to 10 wt.% material extractable by hot water at 95 deg C comprising (A), (B) and/or (C). The polymer (F) is extracted with water to form the copolyamide product (I). Independent claims are included for the copolyamide product (I) and fiber, sheet and molded articles produced using (I).

A biaxially-oriented, shrinkable, heat-fixed tubular film has at least one layer comprising 75-100 wt.% of a partially-aromatic copolyamide made up of (a) 90-98 wt.% units derived from iota -caprolactam and (b) 10-2 wt.% units derived from equimolar amounts of (i) hexamethylenediamine, trimethyl- hexamethylenediamine, isophoronediamine and/or bis(4-aminocyclohexyl)-methane or -propane and (ii) isophthalic-, terephthalic-, 4-Me (or t.Bu)-isophthalic- and/or 1,4- or 2,6-naphthalene dicarboxylic-acid.

Abstract: A polymer based on a dicarboxylic acid and a diamine is prepared by polycondensation in an extruder, by(a) heating a mixture of a dicarboxylic acid having from 4 to 12 carbon atoms and a diamine having from 4 to 12 carbon atoms, which mixture is solid at room temperature and has a residual moisture content of less than 5% by weight, to a temperature in the range from 150 to 400° C. under autogenous pressure in a contrarotating twin-screw extruder to give a product A,(b) feeding the product A to a corotating twin-screw extruder, with the product A being exposed to a temperature in the range from 150 to 400° C. and residual water present and also water from the polycondensation being removed through the degassing openings, to give a product B, with the proviso that the corotating twin-screw extruder has at least two segments having different pressures.
