Friedel crafts alkylation of aromatics using vinyl terminated macromonomers |
| 摘要 |
This invention relates to a polyolefin comprising one or more aromatic moieties according to the following formulae:;
wherein the PO is the residual portion of a vinyl terminated macromonomer (VTM) having had a terminal unsaturated carbon of an allylic chain and a vinyl carbon adjacent to the terminal unsaturated carbon;
Ar is attached to the terminal portion of the VTM to provide PO—Ar or at the vinylidene carbon of the VTM to provide PO—CH(Ar)CH3; andAr is a substituted or unsubstituted aromatic group. |

1. A polyolefin comprising one or more aromatic moieties according to the following formulae: wherein the PO is the residual portion of a vinyl terminated macromonomer (VTM) having had a terminal unsaturated carbon of an allylic chain and a vinyl carbon adjacent to the terminal unsaturated carbon; Ar is attached to the terminal portion of the VTM having an Mn value of greater than 400 g/mole (measured by 1H NMR) and having at least 40% allyl chain ends relative to total unsaturation to provide PO—Ar or at the vinylidene carbon of the VTM to provide PO—CH(Ar)CH3; and Ar is a substituted or unsubstituted aromatic group. |
