    摘要： Random thermoplastic ethylene copolymers can be used to increase the elongation to break and toughness of thermoplastic vulcanizates. Polypropylene is a preferred thermoplastic phase. The rubber can be olefinic rubbers. Random thermoplastic ethylene copolymers are different from Ziegler-Natta ethylene copolymers as the compositional heterogeneity of the copolymer is greater with Ziegler-Natta copolymers. This difference results in substantial differences in properties (elongation to break and toughness) between thermoplastic vulcanizates modified with random thermoplastic ethylene and those modified with Ziegler-Natta ethylene copolymers. An increase in elongation to break results in greater extensibility in the articles made from a thermoplastic vulcanizate.

    摘要： Provided are thermoplastic polymer compositions having a single melting point, articles made therefrom, and methods for elevating the melting point of low melting point polymers. Thermoplastic polymer compositions are composed of one or more high melting point polyolefins and a thermoplastic component that includes a low melting point polypropylene. High melting point polyolefins are composed of a stereoregular polypropylene having a tacticity similar to the low melting point polypropylene. The low melting point polypropylene includes, for example, propylene homopolymers and copolymers composed of propylene and one or more comonomers. Thermoplastic polymer compositions may also optionally contain any of the various additives commonly used in such polymer compositions, such as for example oils, etc. In one embodiment, thermoplastic polymer compositions are thermoplastic elastomer compositions that include an elastomeric component composed of an elastomer or rubber. The elastomeric component may be substantially or partially crosslinked to form a thermoplastic vulcanizate.
