Abstract:
1. A block copolymer composition comprising: (a) 100 parts by weight of a solid hydrogenated controlled distribution block copolymer having the general configuration A-B, A-B-A, (A-B) (b) 5 to 250 parts by weight of a hydrogenated tailored softening modifier which is structurally related to the character of the B block of said controlled distribution block copolymer wherein: (c) wherein said softening modifier is formed in solution in the presence of a solvent in a second reactor to form a second solution and combined with a first solution in a first reactor to form a common solution, wherein said controlled distribution block copolymer is polymerized in said first solution or said common solution, and (d) the solvent is removed from the common solution subsequent polymerization of the controlled distribution block copolymer, providing an intimate mixture of said controlled distribution block copolymer and said tailored softening modifier.
