Polyisobutene composition |
| abstract |
A polyisobutene composition having a global maximum of the differential molecular weight distribution curve at a molecular weight M max of from 3 500 to 8 000 is described, which comprises at least one local maximum at a molecular weight of from 112 to 560. The isobutene oligomers present act as flow improvers and boiling assistants. They are added to higher molecular weight isobutene polymers, preferably before or in the course of a distillation, for removing unconverted isobutene and/or an inert diluent. |
