Abstract

METODO DE PREPARACION DE POLIMEROS RAMIFICADOS DE COMPUESTOS MONOVINILAROMATICOS. COMPRENDE LA POLIMERIZACION DE UN MONOMERO MONOVINIL-AROMATICO, QUE TIENE DE 8 A 18 ATOMOS DE CARBONO POR MOLECULA, COMO ESTIRENO, EN PRESENCIA DE UN INICIADOR DE ORGANOLITIO, COMO SEC-BUTIL-LITIO; ADICION DE AL MENOS UN MONOMERO DE DIENO CONJUGADO QUE TIENE 4 A 12 ATOMOS DE CARBONO POR MOLECULA, COMO 1,3-BUTADIENO; CONTINUACION DE LA POLIMERIZACION Y COPULACION DE LAS CADENAS DE COPOLIMERO DE BLOQUES RESULTANTES EN PRESENCIA DE UN FOSFITO DE TRIS-(FENILO NONILADO), COMO AGENTE DE COPULACION, EN PROPORCION DE 0,15 A 11 MOLES POR MOL DE INICIADOR, TODO ELLO A UNA TEMPERATURA COMPRENDIDA ENTRE C20JC Y 150JC.
