A series of hydrogenated natural rubbers, HNRs, were prepared by homogenous hydrogenation using H 2 gas with a rhodium catalyst (chlorotris(triphenylphosphine)rhodium) in toluene. The HNRs were linear polymers with molecular weights greater than 800,000. These rubbers were vulcanized using sulfur and peroxide compounds. Vulcanized 100% HNR has a low glass transition temperature ( T g = −43°C) and excellent abrasion resistance, and is resistant to oxidation and ozonolysis ageing. © 2006 Wiley Periodicals, Inc.
