Abstract: PROBLEM TO BE SOLVED: To provide a compatibilized, thermoplastic polyphenylene ether- polyamide composition having an improved impact resistance and ductility at a wide range of temperature, especially at a low temperature. SOLUTION: The titled composition contains (a) a compatibilized polyphenylene ether-polyamide resin mixture and (b) an alkylene-alkyl (meth) acrylate copolymer containing at least two portions chosen from the group consisting of a carboxylic acid, an acid anhydride, an epoxy, an oxazoline and an orthoester, wherein the alkylene-alkyl (meth)acrylate copolymer exists at an amount of from about 1 to about 15% of the total weight of the composition.

Abstract: The invention relates to a method for the continuous production of copolyamides which are based on a lactame (I), a diamine (II) and a dicarboxylic acid (III). The inventive method is characterised in that a mixture (IV) containing a diamine (II), a dicarboxylic acid (III) and water is converted to a polymer in a first reaction area at a pressure of 1,3*10 5 to 2,5*10 5 Pa in the entry part of the reaction area, at a temperature above the melting point of the polymer (V) and with a degree of conversion of at least 80 % in relation to the molar quantities of diamine (II) and dicarboxylic acid (III), in that a mixture (VI) containing lactame (I) and water is converted to a polymer (VII) in a second reaction area at a pressure of 5*10 5 to 40*10 5 Pa, at a temperature above the melting point of the polymer (VII) and with a degree of conversion of at least 80 % in relation to the molar quantity of lactame (I), in that polymer (V) and polymer (VII) are then reacted with each other in a third reaction area at a pressure of 1*10 5 to 1,5*10 5 Pa in the entry part of the reaction area, at temperatures above the melting temperature of the polymer (VIII), to produce the polymer (VIII). Polymer (VIII) contains a maximum of 10 wt. % constituents that are extractable with water at a temperature of 95.degree.C, in relation to lactame (I), diamine (II) and dicarboxylic acid (III). The polymer (VIII) is then extracted with water so as to obtain the copolyamide. The invention also relates to copolyamides obtained using this method and to the ir use in the production of fibres, sheet structures and moulded bodies which are based on these copolyamides.

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.
