Abstract
Embodiments of the present disclosure are directed to polyolefin grafted polydiene polymers, wherein the polyolefin grafted polydiene polymers comprises a polydiene having a polydiene polymer backbone, a polyolefin, and at least one sulfur containing functionalizing agent which grafts the polyolefin onto at least one non-terminal position on the polydiene polymer backbone.
Claims13
A polyolefin grafted polydiene polymer comprising:
- a polydiene having a polydiene polymer backbone;
- a polyolefin having an anhydride polymeric modifier;
- and
- at least one sulfur containing functionalizing agent which grafts the polyolefin onto at least one non-terminal position on the polydiene polymer backbone.
1 more element
A method of producing a polyolefin grafted polydiene polymer comprising:
- reacting a polyolefin having an anhydride polymeric modifier with at least one sulfur containing functionalizing agent to produce a functionalized polyolefin;
- and
- producing the polyolefin grafted polydiene polymer by reacting the functionalized polyolefin with an unsaturated polydiene polymer.
