Abstract
Polymers are prepared containing a hydrogenated block derived from low vinyl polybutadiene, and a hydrogenated block derived from medium vinyl polybutadiene. The polymers further can contain a block derived from a monovinyl-substituted aromatic compound. The polymers are ozone-resistant, thermoplastic elastomers, with improved high temperature tensile strengths.
