ABSTRACT:
A semi-continuous process for the preparation of star-block copolymers of 25-55% by weight of monovinyl aromatic compound and 45-75% by weight of conjugated diene monomer has been developed. The process reduces the time needed to produce the copolymer by shortening reaction time and eliminating the need for costly cleanout between runs.
