Abstract

PREPARACION DE POLIMEROS DE ESTRELLA, INCLUYENDO LOS ACRILICOS, POR TECNICAS DE TRANSFERENCIA DE GRUPOS, MEDIANTE METODOS DE BRAZO-INICIAL, NUCLEO-INICIAL O BRAZO-NUCLEO-BRAZO. ESTOS POLIMEROS TIENEN: A) UN NUCLEO FORMADO POR UN POLIMERO DERIVADO DE UNA MEZCLA DE: I) 1-100% EN PESO DE UNO O MAS MONOMEROS QUE TIENEN CADA UNO AL MENOS DOS GRUPOS; E II) DE 0 A 99% EN PESO DE UNO O MAS MONOMEROS QUE TIENEN CADA UNO UN GRUPO; Y B) UNIDOS AL NUCLEO, AL MENOS CINCO BRAZOS QUE COMPRENDEN CADENAS DE POLIMERO, DERIVADAS DE MONOMEROS QUE TIENEN CADA UNO UN GRUPO, DONDE R ES H, CH3, CH3-CH2-, CN O CO2R Y ZK ES O O NRK Y RK ES UN ALQUILO DE 1-4C. SE OBTIENEN EMPLEANDO UN INICIADOR DE POLIMERIZACION, EN RELACION MOLAR CON EL MONOMERO MENOR O IGUAL QUE 1:1.
