Abstract

La invenzione concerne l'aumento della rigidità di poliammide colata rinforzata con fibre di vetro ed eventualmente in aggiunta con caolino oppure creta, mediante la aggiunta di polistirene alla massa fusa di lattami e mediante successiva polimerizzazione.The invention relates to the increase in the rigidity of cast polyamide reinforced with glass fibers and optionally in addition with kaolin or clay, by adding polystyrene to the melt of lactam and by subsequent polymerization.
