Abstract

ESTE PROCEDIMIENTO PARA LA PREPARACION DE COPOLIMEROS DE ACIDOS DICARBOXILICOS, CONSISTE EN DISOLVER, EN UN MEDIO ACUOSO DESIONIZADO, UN ACIDO DICARBOXILICO, O SUS SALES ALCALINAS O AMONICAS, EN PRESENCIA DE PEQUEÑAS CANTIDADES DE IONES METALICOS POLIVALENTES Y EN ATMOSFERA INERTE, TRAS LO CUAL LA MEZCLA SE CALIENTA Y SE LE ADICIONA UN MONOMERO SOLUBLE EN AGUA Y UN GENERADOR DE RADICALES LIBRES SOLUBLES EN AGUA COMO INICIADOR DE LA REACCION, LA CUAL SE LLEVA A CABO A PH ENTRE 4 Y 6. CON ESTE PROCEDIMIENTO SE CONTROLA CON GRAN PRECISION EL PESO MOLECULAR DEL COPOLIMERO. ESTOS PRODUCTOS SON DE APLICACION EN LA FORMULACION DE COMPOSICIONES DETERGENTES PARA EL LAVADO DE TEJIDOS Y OTROS, COMO ANTIINCRUSTANTE.
