Abstract

"PROCESSOS PARA POLIMERIZAR PRé-POLìMEROS DE POLIéSTER". Trata-se de um processo para aumentar a velocidade de polimerização de partículas de poliéster de baixo peso molecular sob condições de processamento em estado sólido, por meio do qual o progresso da polimerização é preferido em relação ao progresso da cristalização para uma determinada massa de partículas.
