Process for the preparation of end-products based on vinylaromatic polymers with a predominantly syndiotactic structure

摘要

Process for the preparation of end-products based on vinylaromatic polymers with a predominantly syndiotactic structure which comprises: a) compressing the polymer in powder form in a mould at a pressure ranging from 0.1 to 500 Mpa; b) sintering the compressed powder, under pressure, at a temperature ranging from the glass transition temperature of the polymer (Tg) to 150 DEG C; c) slowly cooling the end-product to room temperature. c
