SEMI-CONTINUOUS INTEGRATED PROCESS FOR THE PRODUCTION OF HIGH IMPACT VINYL AROMATIC (CO)POLYMERS BY ANIONIC/RADICAL POLYMERIZATION IN SEQUENCE
摘要
Butadiene is anionically polymerized (or block copolimerized with styrene) in a low-boiling non-polar solvent in presence of rganolithiura compounds. At the end of the polymerization, the non-polar solvent is switched with styrene and the new solution is stored in tanks in relation to the type of polybutadiene (or its block copolymer with styrene) obtained. The polybutadiene solution (and/or its block copolymer with styrene) with the desired set of properties is then fed to a production plant of high impact vinyl aromatic (co) polymers.
