Abstract

SE PRESENTA UN PROCESO PARA LA PREPARACION DE POLIMEROS QUE TENGAN UNOS PESOS MOLECULARES INFERIORES A 5.000 Y UNA POLIDISPERSABILIDAD INFERIOR A 2,5. LA POLIMERIZACION SE LLEVA A CABO EN DIOXIDO DE CARBONO SUPERCRITICO A TEMPERATURAS DE 200 (GRADOS) C POR LO MENOS Y PRESIONES SUPERIORES A 3.500 PSI. EL PROCESO PUEDE SER CONTINUO, SEMICONTINUO O POR PARTES. LOS POLIMEROS SON UTILES COMO ADITIVOS DETERGENTES, INHIBIDORES DE INCRUSTACIONES, DISPERSANTES Y MODIFICADORES DEL CRECIMIENTO DE CRISTALES.
