Abstract
The present invention relates to gels prepared from novel anionic block copolymers of mono alkenyl arenas and conjugated dienes, and to blends of such block copolymers with such polymers. The block copolymers are selectively hydrogenated and have A polymer blocks and B polymer blocks wherein A represents a polymer block of a mono alkenyl arene and B represents a polymer block of a conjugated diene. The block copolymer may be combined with tackifying resins, oils and other components to form the gel of the present invention.
