| titleOfInvention | Copolymer having low cyclic oligomer content |
| abstract | The copolymers have low levels of cyclic oligomeric compounds, which are undesirable impurities in certain fields. The cyclic oligomeric compounds are advantageously provided in a low proportion of C21 / C13 oligomers. C13 oligomers can be extracted using steam to further reduce the total amount of cyclic oligomers. A process for preparing a copolymer having low levels of cyclic oligomers comprises reacting at least one isoolefin monomer with at least one multi-olefin and / or < RTI ID = 0.0 >Lt; / RTI > monomer. The diluent contains a hydrofluoroolefin (HFO) comprising at least three carbon atoms and at least three fluorine atoms. The hydrofluorinated olefins used in the present invention are diluents superior to saturated hydrofluorocarbons for butyl slurry cationic polymerization. |
