Abstract
The invention is based on the discovery of useful combinations of fully cross-linked thermoplastic vulcanizates with styrenic block copolymers. The new combinations of the invention can provide a synergistic effect. Specifically, the compositions formed thereby can be both softer and more elastic than would be expected on the basis of the properties of the individual components. Such compositions can be used in numerous applications, including, for example, any application for which a soft material with very good recovery is desired.
Claims23
A composition comprising:
- a styrenic block copolymer;
- and
- a substantially fully cross-linked thermoplastic vulcanizate.
A composition comprising:
- a styrenic block copolymer having a styrene-ethylene butylene-styrene structure, a styrene-ethylene propylene-styrene structure, or a styrene-ethylene ethylene propylene-styrene structure;
- and
- a substantially fully cross-linked blend of polypropylene and an ethylene-propylene-diene copolymer rubber.
