Abstract

"PROCESSO A VáCUO PARA A FABRICAçãO DE COPOLìMEROS DE SILOXANO-OXIALQUILENO" Apresenta-se um processo aperfeiçoado para a fabricação de copolímeros contendo silicone mediante uma reação de hidrossilação, em que a reação catalisada de organo-hidrossiloxano e poliéter olefínico é realizada entre 20 - 120°C, de preferência 70 - 120°C, sob um vácuo entre 750 - 1mmHg. A reação sob essas condições resulta em um copolímero de qualidade superior quando comparado a copolímeros preparados pelo processo tradicional, sem o benefício do vácuo.
