Abstract

LOS OLIGOMEROS DE POLICARBONATO QUE TIENEN GRUPOS FINALES HIDROXI SE PRODUCEN POR REACCION DE FUNDIDO CON BISFENOL UN CATALIZADOR BASICO. LOS OLIGOMEROS PUEDEN ENTONCES HACERSE REACCIONAR CON CLORO SILOXANOS DE GRUPO FINAL EN LA PRESENCIA DE UN SOLVENTE UN ACIDO ACEPTADOR PARA ARROJAR COPOLIMEROS EN BLOQUE DE POLICARBONATO POLISILOXANO. LA REACCION DE FUNDIDO OCURRE A TEMPERATURA ELEVADA SIN EL USO DIRECTO DE GAS FOSGENO.
