    摘要： A composition comprising a dynamically-cured rubber and thermoplastic resin, where the rubber includes one or more mer units of divinyl benzene, and where the rubber is dynamically cured with a free-radical curative. In one or more embodiments, the rubber is highly cured, and therefore the composition may exhibit technologically useful engineering properties. Also, this cure can be achieved in one or more embodiments with reduced curative and/or reduced diene content.
