Abstract

Un processo per la produzione di un polimero espanso comprende le fasi di: miscelare in un dissolutore una miscela costituita da almeno un isocianato e da una prima anidride insatura che viene introdotta nel dissolutore allo stato liquido e ad una temperatura relativamente elevata; raffreddare progressivamente detta miscela in continua agitazione fino al raggiungimento di una temperatura non superiore ai 22°C; introdurre nella miscela in continua agitazione una seconda anidride insatura, almeno un agente gonfiante, un composto vinilidenico, cloruro di polivinile ed uno stabilizzante al calore; mantenere la miscela in continua agitazione alla temperatura suddetta sino all'ottenimento di una pasta che viene versata, previo filtraggio, in uno stampo o in un contenitore; indurire la pasta mediante introduzione del contenitore in un forno a pressione atmosferica e ad una temperatura non superiore a 8O°C; portare a termine l'indurimento della pasta sotto pressione, mediante innalzamento della temperatura sino a 180°C e successivo raffreddamento sino all'ottenimento di embrioni parzialmente espansi; e terminare il processo di espansione degli embrioni mediante riscaldamento.
