PROCEDIMIENTO PARA LA PRODUCCION DE ARTICULOS DE MOLDEO DE POLIAMIDAS A PARTIR DE LACTAMAS. |
摘要 |
<p>This invention relates to a process for the production of polyamide mouldings which comprises polymerizing a mixture consisting of a lactam, a catalyst and an activator in a screw injection moulding machine, said mixture being delivered to said screw injection moulding machine under the effect of an external pressure. The mixture is delivered at a pressure of at least 2 atms. under the influence of a pressure generator through a feed opening to the feed zone and a screw injection moulding machine and is polymerized in the injection moulding machine to form a polyamide at a temperature above the melting temperature of the polyamide and the resulting polyamide melt is forced by the injection moulding machine into a mould.</p> |
