Abstract

PROCEDIMIENTO PARA PREPARAR COMPOSICIONES DE CAUCHO SIN CURAR. COMPRENDE: A) POLIMERIZAR O COPOLIMERIZAR ANIONICA DE UN MONOMERO DIENICO, EN PRESENCIA DE UN CATALIZADOR COMO METAL ALCALINO O COMPUESTO DE METAL ALCALINO PARA PRODUCIR CAUCHO POLIMERICO; B) HACER REACCIONAR AL CAUCHO POLIMERICO QUE CONTIENE METAL ALCALINO CON UN COMPUESTO HETEROCICLICO AROMATICO, NITROGENADO DE 6 MIEMBROS SUSTITUIDO CON UN GRUPO QUE NO CONTIENE HIDROGENO; Y C) TRATAR AL CAUCHO DE B) CON UN HALURO DE FORMULA (AR)A C(H)B - XC, PARA PRODUCIR SALES DE AMONIO CUATERNARIAS EN LAS MITADES HETEROCICLICAS NITROGENADAS DEL CAUCHO. EL CAUCHO POLIMERICO SE ELIGE ENTRE: BR BUTADIENO; IR ISOPRENO Y NR CAUCHO NATURAL; EL METAL ALCALINO ES LI, NA, RB Y CS, LAS COMPOSICIONES DE METAL ALCALINO DERIVADOS ORGANOMETALICOS DE LOS METALES COMO N-BUTIL-LITIO, 2-NAFTIL-SODIO, ETC., LOS COMPUESTOS HETEROCICLICOS AROMATICOS NITROGENADOS SE ELIGEN ENTRE COMPUESTO DE QUINOLINA, PIRIDINA O PIRAZINA CON SUSTITUYENTES ELEGIDOS ENTRE -NO Y -CN. SIENDO: AR UN GRUPO AROMATICO; X, HAL; A Y C 1 A 3; Y B, 3.
