    摘要: A mid-range vinylidene content, high viscosity PIB polymer composition including PIB molecules, wherein a first portion of the PIB molecules have alpha position double bonds and a second portion of the PIB molecules have beta position double bonds, and the first and second portions together include at least 80 mole % of the PIB molecules of the composition. The first portion includes less than 75 mole % of the PIB molecules of the composition. Additionally, no more than 10 mole % of the PIB molecules of the composition have tetra-substituted double bonds, while the composition is further characterized by having a polydispersity of no more than 2.7 and in that the composition has a kinematic viscosity in the range of 3000 cSt to 5000 cSt, a number average molecular weight, Mn, in the range of 2800 Daltons to 4000 Daltons and a ratio of Mn:PDI of greater than 1100.
