Abstract

"PROCESSO PARA A PRODUçãO DE PARTìCULAS DE POLIOLEFINA EXPANDIDAS". A invenção diz respeito a um método para produzir partículas de poliolefina expandidas ou expansíveis, pela impregnação da poliolefina granulada com um agente propulsor volátil em suspensão sob pressão. Uma mistura de um composto inorgânico insolúvel em água e de um tensoativo é usada como um agente auxiliar de suspensão e a impregnação acontece na presença de um polímero ativo na superfície que carrega grupo carboxila ou carboxilato.
