Abstract
PROCEDIMIENTO DE OBTENCION DE FIBRILLAS A BASE DE POLIOLEFINAS. CONSISTE EN EFECTUAR UNA EXPANSION BRUSCA POR PASO A TRAVES DE UN ORIFICIO DE UNA MEZCLA LIQUIDA DE POLIOLEFINA FUNDIDA Y DE DISOLVENTE. SE PRODUCE UNA VAPORIZACION INSTANTANEA DEL DISOLVENTE Y LA SOLIDIFICACION DE LA POLIOLEFINA EN FORMA DE FIBRILLAS. SE EMPLEA UNA POLIOLEFINA DE BAJO PESO MOLECULAR INJERTADA, COMPRENDIDA ENTRE 5 Y 40 POR 100 DEL PESO DE LAS POLIOLEFINAS PRESENTES EN LA MEZCLA.
