Abstract:
1. A method for making a dynamically crosslinked thermoplastic material, comprising: (a) partially crosslinking an elastomer composition at a first crosslinking temperature to form a thermoplastic, partially crosslinked elastomer composition; (b) mixing a thermoplastic polymer composition with the thermoplastic, partially crosslinked elastomer composition and heating the mixture to a second crosslinking temperature higher than the first crosslinking temperature, wherein the thermoplastic polymer composition is liquid at the second crosslinking temperature; and (c) continuously mixing the mixture while further crosslinking the elastomer composition to form a thermoplastic material having a dispersed phase of crosslinked elastomer composition in the thermoplastic polymer composition.
