Abstract

PROCEDIMIENTO PARA LA COPOLIMERIZACION CONTROLADA DE ACRILAMIDA Y N,N''-METILENBISACRILAMIDA Y, OPCIONALMENTE OTROS MONOMEROS N-SUSTITUIDOS DE ACRILAMIDA, EN UNA PROPORCION ENTRE MONOMEROS Y AGUA NO SUPERIOR A 2:8. MIENTRAS SE AGITA LA DISOLUCION, SE AÑADE UN INICIADOR DE POLIMERIZACION TAL COMO AMINAS TERCIARIAS Y-O UN PEROXIDO INORGANICO Y SE POLIMERIZA A TEMPERATURAS SUPERIORES A 50 C. EL GEL OBTENIDO SE GRANULA, SE LAVA HASTA UN MAXIMO DE MONOMEROS DE 0,1 POR 100, Y SE SECA CON AIRE A TEMPERATURAS INFERIORES A 100 C, HASTA UN MAXIMO DE 12 POR 100 DE AGUA. ESTOS COMPUESTOS TIENEN APLICACIONES COMO TENSOACTIVOS CATIONICOS O NO IONICOS EN LA TECNOLOGIA AGRARIA.
