Abstract

"PROCESSOS PARA A CRISTALIZAçãO TéRMICA DE UM POLìMERO DE POLIéSTER, PARA A PRODUçãO DE UMA PEçA OU CHAPA MOLDADA A PARTIR DOS GRáNULOS E PARA A CRISTALIZAçãO TéRMICA DE GRáNULOS SóLIDOS EM UM TUBO". Processo para a cristalização térmica de um polimero de poliéster, através da introdução dos grânulos em um meio liquido tendo uma temperatura de pelo menos 140<198>C dentro de uma zona de meio liquido, e cristalizando os grânulos submersos na ou acima da pressão de vapor do meio liquido sem aumentar o peso molecular dos grânulos, enquanto a pressão em pelo menos uma porção dos grânulos é igual ou maior do que a pressão de vapor do meio liquido, a separação de pelo menos uma porção dos referidos grânulos e pelo menos uma porção do meio liquido uma da outra. A cristalização, desejosamente, é conduzida na zona de meio líquido sem agitação induzida mecanicamente. Opcionalmente, os grânulos são formados por um pelotizador submerso. é também apresentado um processo para a cristalização térmica de grânulos sólidos em um tubo, direcionando o fluxo de grânulos sólidos em um meio liquido através de um tubo, tendo uma relação de aspecto L/D de pelo menos 50:1, onde os grânulo sólidos são cristalizados no tubo em uma temperatura do meio liquido maior do que a T~ g~ do polímero de poliéster.
