Abstract
Disclosed herein are processes for preparing a resin-extended rubber by mixing at least one thermoplastic resin with a resin-rubber-solvent cement comprising at least one conjugated diene monomer-containing rubber and the resin-extended rubber resulting from such processes. Also disclosed is a resin-extended rubber-solvent-cement comprising at least one conjugated diene monomer-containing rubber, at least one non-polar solvent, and at least one thermoplastic resin as well as a rubber composition comprising a resin-extended rubber.
Claims10
A process for preparing a resin-extended rubber, the process comprising
- a. polymerizing at least one conjugated diene monomer in at least one non-polar solvent to produce a rubber-solvent-cement comprising the polymerized at least one conjugated diene monomer-containing rubber and the at least one non-polar solvent,
- b. mixing the rubber-solvent-cement with at least one thermoplastic resin in the same at least one non-polar solvent to produce a resin-rubber-solvent-cement,
- c. producing a resin-extended rubber by removing the at least one non-polar solvent from the resin-rubber-solvent-cement,
- wherein the at least one thermoplastic resin of (b) is utilized in an amount of up to 100 phr.
