FIELD: machine building.
SUBSTANCE: procedure consists in condensing polyamide moulding blend, polyamide of which has at least 30 % of end groups in form of end amino-groups of polycarbonate with 0.005 to 10 wt % in terms of used polyamide. At stage a) there is prepared polyamide moulding blend, b) there is produced mixture of polyamide moulding blend and polycarbonate, c) if necessary, blend is stored and/or transported by point b) and d) mixture is processed by point b) into a moulded item. The item corresponds to a hollow item or hollow profile with external diametre at least 30 mm and thickness of wall at least 1 mm. Condensing occurs only at stage of processing.
EFFECT: increased stiffness of melt at simultaneous reduced pressure during processing and insignificant load on engine, simplification of moulded items production.
