Abstract

EN UNA POLIMERIZACION DE SUSPENSION DE ESTER ACIDO ACRILICO O DE AROMAS DE VINILO O EN LAS MEZCLAS DE ALGUNOS MONOMEROS SE ORIGINA UN POLIMERISADO DE EMULSION COMO PRODUCTO SECUNDARIO, QUE REDUCE EL RENDIMIENTO. SE TIENDE A QUE LA PARTE DE POLIMERIZADO DE EMULSION PERMANEZCA LO, MAS PEQUEÑA POSIBLE, PORQUE ESTE DISMINUYE LAS PROPIEDADES FISICAS DEL POLIMERIZADO DE SUSPENSION. LA FORMACION DE POLIMERIZADOS DE EMULSION SE DISMINUYE CUANDO SE EFECTUA LA POLIMERIZACION BAJO EL ESTADO DE ACIDOS DE FOSFORO DE DIFERENTES VALORES O SUS SALES DE AMONIO O DE METALES ALCALINOS O BAJO EL ESTADO DE SALES DE AMONIO O DE METALES ALCALINOS DE FOSFATOS INORGANICOS CONDENSADOS, POR EJEMPLO DE SALES DE GRAHAM. ELABORACION DE POLIMERIZADOS DE SUSPENSION ESPECIALMENTE EN BASE A PMMA PARA LA ELABORACION DE ARTICULOS DE PLASTICO.
