Abstract

Un proceso para la terminacion mediante coagulacion de (co)polímeros utilizando alcohol polivinílico como dispersante durante la coagulacion. En particular se pueden terminar exitosamente copolímeros en bloque de baja viscosidad, que comprenden cuando menos un bloque de predominantemente dieno conjugado y cuando menos un bloque de monomero aromático predominantemente monovinilo. El alcohol polivinílico se caracteriza por un peso molecular promedio en peso de 200 a 200,000 y por un grado promedio de hidrolisis de 25 a 98%.
