Abstract
The present invention relates to selectively hydrogenated block copolymers where one of the blocks is a random copolymer of a mono-alkenyl arene monomer, such as styrene, and a 1,3-cyclodiene monomer, such as 1,3-cyclohexadiene, and one of the other blocks is a hydrogenated polymer or copolymer of an acyclic conjugated diene, such as 1,3-butadiene or isoprene.
