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.THIS PROCEDURE FOR THE PREPARATION OF COPOLYMERS OF DICARBOXYLLIC ACIDS, CONSISTS IN DISSOLVING, IN A DEIONIZED AQUEOUS MEDIUM, A DICARBOXYLIC ACID, OR ITS ALASAL SALTS, EASTERN AND IASALES METALS IN IOSALES, METALS MIXTURE IS WARMED UP AND A WATER-SOLUBLE MONOMER AND A GENERATOR OF FREE RADICALS SOLUBLE IN WATER AS INITIATOR OF THE REACTION, WHICH IS CARRIED OUT AT PH BETWEEN 4 AND 6. WITH THIS PROCEDURE, THE WEIGHT IS VERY PRECISELY CONTROLLED COPOLYMER MOLECULAR. THESE PRODUCTS ARE APPLICABLE IN THE FORMULATION OF DETERGENT COMPOSITIONS FOR THE LAUNDRY OF TISSUES AND OTHERS, AS AN ANTI-INCRUSTANT.
