Abstract

2.1 PARA LA UTILIZACION DE BOTELLAS DE BEBIDA A PARTIR DE PVC SON NECESARIOS ADEMAS MEDIOS AUXILIARES DE PREPARACION PVC POBRES EN MONOMEROS RESIDUALES. A UN PROCESO DE ELIMINACION DE MONOMEROS RESIDUALES CONOCIDO PERTENECEN LAS DERIVACIONES DE VAPOR DE AGUA, LOS CATALIZADORES POSTERIORES CONOCIDOS O EL SECADO DE ROCIADO. LA UTILIZACION DE ESTE PROCESO NO ES CORRECTO EN GENERAL PARA CONSEGUIR EL CONTENIDO DE MONOMEROS RESIDUALES NECESARIO REDUCIDO. EN PARTICULAR EN LA CONSIDERACION DEL SECADO DE ROCIADO DEBE TENERSE EN CUENTA CON FRECUENCIA LA VITRIFICACION, ES DECIR LA SINTERIZACION CONJUNTA DE LAS PARTICULAS DE POLVO INDIVIDUALES. LOS MEDIOS AUXILIARES DE ELABORACION VITRIFICADOS PUEDEN QUE NO CUMPLAN MAS SU FUNCION CORRESPONDIENTE. 2.2 LAS DESVENTAJAS CONOCIDAS SE SUPERAN MEDIANTE UN PROCESO PARA LA ELABORACION DE HOMOPOLIMERIZADOS O COPOLIMERIZADOS POBRES DE MONOMEROS RESIDUALES DE MMA, DONDE SE SOMETE UN POLIMERIZADO DE EMULSION PRIMERO A UN CATALIZADOR POSTERIOR Y DESPUES SE SECA MEDIANTE ROCIADO. DE FORMA SORPRENDENTE SE CONSIGUE LA ELABORACION DE UN POLIMERIZADO DE EMULSION NO VITRIFICADO, SECADO MEDIANTE ROCIADO A PARTIR DE PMMA, QUE SE CARACTERIZA POR UN CONTENIDO EN MONOMEROS RESIDUALES DE MENOS DE 50 PPM. 2.3 UTILIZACION COMO MEDIO AUXILIAR DE ELABORACION PARA POLIMEROS TERMOPLASTICOS, EN PARTICULAR PVC, POR EJEMPLO PARA BOTELLAS DE BEBIDA A BASE DE PVC.
