Mid-range vinylidene content polyisobutylene polymer product and process for producing the same |
abstract |
A relatively low molecular weight, mid-range vinylidene content PIB polymer product and a process for making the same. At least about 90% of the PIB molecules present in the product comprise alpha or beta position isomers. The vinylidene (alpha) isomer content of the product may range from 20% to 70% thereof and the content of tetra-substituted internal double bonds is very low, preferably less than about 5% and ideally less than about 1-2%. The midrange vinylidene content PIB polymer products are prepared by a liquid phase polymerization process conducted in a loop reactor at a temperature of at least 60° F. using a BF 3 /methanol catalyst complex and a contact time of no more than 4 minutes. |
