Abstract
Official abstract text for this publication.
Branched polymers including multi-branched polymers, functionalized branched polymers, star-branched polymers, and dendigraft polymers. Methods for the synthesis of branched polymers and method for the use of branched polymers in tire components are also included.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of preparing a branched polymer, the method comprising the steps of: (a) polymerizing conjugated diene monomer with a catalyst system that is the combination or reaction product of (i) a lanthanide compound, (ii) an alkylating agent, (iii) a nickel-containing compound, and (iv) a source of halogen to form a high-cis polydiene; and (b) coupling the high-cis polydiene with a free radical source. 2. The method of claim 1 , furt…
