Abstract
Official abstract text for this publication.
A method for making a thermoplastic material includes: (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. The elastomer composition may include an elastomer compounded with a curing agent and optionally additional components. A thermoplastic material resulting from this process may be molded or shaped by any method used for forming thermoplastic materials into articles, such as molding, extrusion, or thermoforming.
