COPOLYMER COMPOSITIONS CONTAINING A NARROW MWD COMPONENT AND PROCESS OF MAKING SAME |
摘要 |
A polymeric composition of a first copolymer which includes at least one copolymer having at least one of M &cir& NOt w/M &cir& NOt n less than 2 and M &cir& NOt z/M &cir& NOt w less than 1.8; and a second copolymer having M &cir& NOt w/M &cir& NOt n greater than or equal to 2. The composition can be produced by preparing the first and second copolymers in different reactors and blending them. The blend can also be produced in a single reactor by initiating the reaction to prepare one copolymer, and adding additional reactants, or recycling the reaction mixture, during the reaction to produce the other polymer. The blend so produced may be incorporated in a lubricating oil to improve the viscosity index of the lubricating oil composition. Said blend may also be used in an elastomeric composition with good processability and good cure rate. |
