Abstract

ABC BLOCK COPOLYMERS ON THE BASIS OF BUTADIENE, ISOPRENE AND OPTIONALLY STYRENE, ARE PROVIDED BY A POLYMERIZATION PROCESS WHEREIN THE RESULTANT BLOCK COPOLYMER COMPRISES: ABOUT 40 TO 75 WT% OF A BLOCK A BASED ON BUTADIENE (UNIFORMLY DISTRIBUTED VINYL GROUP CONTENT LESS THAN ABOUT 15 WT%), UP TO ABOUT 25 WT% OF A BLOCK B BASED ON BUTADIENE AND ISOPRENE (VINYL CONTENT LESS THAN ABOUT 15 WT%) OR BASED ON BUTADIENE (VINYL CONTENT MORE THAN ABOUT 75 WT%) ABOUT 20 TO 55 WT% OF A BLOCK C BASED ON BUTADIENE AND ISOPRENE (VINYL CONTENT MORE THAN ABOUT 75 WT%).THE ABC BLOCK COPOLYMERS ARE USEFUL FOR THE PRODUCTION OF TIRE TREADS.
