Abstract

EN LAS POLIMERIZACIONES Y COPOLIMERIZACIONES EN FASE DE GAS DE ETILENO, LOS REACTIVOS O COALIMENTOS CONTROLAN EL PESO MOLECULAR, EXPRESADO COMO MI (EN DONDE MI SE MIDE SEGUN EL ESTADO E DE ASTM D-1238), DEL PRODUCTO DE RESINA. SI SE UTILIZAN COMPUESTOS DE ISOPENTANO Y DONADORES DE ELECTRONES SE REDUCE EL MI; MIENTRAS QUE LOS COMPUESTOS QUE ELIMINAN EL AGUA Y LOS ELECTRONES AUMENTAN EL MI.
