Cocatalysts useful for preparing polyethylene pipe |
| abstract |
Commonly used triethyl aluminum and tri-isobutyl aluminum cocatalysts may be replaced in olefin polymerizations with a cocatalyst conforming to the formula n nAlR z (X z ) n L z m n nwherein R z is a linear or branched organic moiety having at least 5 carbons and X z is a linear or branched organic moiety having at least 5 carbons or heteroatom substituted organic moiety or a heterocyclic moiety having at least 4 atoms and may be anionic (n=2) or dianionic (n=1). X z may also be hydrogen. The general formula is subject to the proviso that when n=2, each X z may be the same or different and that both X z moieties may not be hydrogen. The aluminum complex may also be in the form of an adduct complex where L z is a Lewis base and m=1-3. Use of the invention enables production of a polyolefin pipe, such as polyethylene pipe, exhibiting improved processing, crack resistance and other desirable properties. |
