Abstract

PROCEDIMIENTO PARA LA PREPARACION DE POLIMEROS DE CAPROLACTAMA DOTADOS DE ELEVADA RESISTENCIA AL IMPACTO. CONSISTE EN SOLUBILIZAR UN ELASTOMERO COPOLIESTERAMIDICO EN LA CAPROLACTAMA MONOMERO O EN PARTE DE LA MISMA Y SOMETER LA SOLUCION Y EL EVENTUAL MONOMERO RESIDUAL A LA POLIMERIZACION EN PRESENCIA DE UN INICIADOR BASICO COMO SODIO METALICO E HIDRURO DE LITIO Y DE UN ACTIVADOR DE POLIMERIZACION COMO N-ACETILCAPROLACTAMA DANDO LUGAR A POLIMEROS DE CAPROLACTAMA CONTENIENDO UNA FASE GOMOSA CONSTITUIDA POR COPOLIESTERAMIDAS ALTERNADAS ELASTOMERICAS HOMOGENEAMENTE DISTRIBUIDA EN EL INTERIOR DEL POLIMERO EN UNA CANTIDAD COMPRENDIDA ENTRE EL 5 Y EL 20 POR CIENTO EN PESO DONDE EL INICIADOR SE ADICIONA EN UNA CANTIDAD DE 0,2 POR CIENTO MOLAR Y EL ACTIVADOR SE ADICIONA EN UNA CANTIDAD DE 0,6 POR CIENTO MOLAR CON RESPECTO A LA CAPROLACTAMA Y DONDE SE OBTIENEN POLIMEROS DE CAPROLACTAMA CON UN VALOR DE RESISTENCIA AL IMPACTO SUPERIOR A 100J/M.
