Preparation method of diene copolymer having improved rolling resistance and wet traction.U.S. patent: 7,151,140 Issued: December 19, 2006 Inventors: Young-Chang Jang, Hyung-Kyu Choi, Shin Han and Young-Hoon Ko Assigned: Korea Kumho Petrochemical Key statement: A copolymer copolymer: see polymer. is made by coupling the ends of a living polymer obtained from copolymerization copolymerization (kōpäl´im  rizā´sh of a diene Dienes are hydrocarbons which contain two double bonds. Dienes are intermediate between alkenes and polyenes. ClassesDienes can be divided into three classes:
amine Any of a class of nitrogen-containing organic compounds derived, either in principle or in practice, from ammonia (NH3). compound. This improves the affinity to silica and greatly enhances the dynamic properties required for tires, such as wet traction and rolling resistance. |
