| titleOfInvention | Process for the production of olefin polymers using an organo-phosphorus catalyst compound |
| abstract | A process for the production of olefin polymers which comprises contacting at least one olefin monomer with an olefin polymerization catalyst comprising: n (1) a solid compound of titanium, vanadium or zirconium wherein the metal has a valency below its maximum, n (2) a Grignard reagent which is substantially ether free, n n Mg[Al(C.sub.2 H.sub.5).sub.4 ].sub.2, Mg(C.sub.6 H.sub.5).sub.2, n n a lithium aluminium tetraalkyl, an aluminium hydrocarbyl halide, an aluminium hydrocarbyl sulphate, an aluminium hydrocarbyl oxyhydrocarbyl, an aluminium trihydrocarbyl or a dihydrocarbyl aluminium hydride, the improvement of adding to the polymerization system up to C a /f molecular proportions of a trivalent phosphorus compound of the formula n n PR'.sub.3-n (X--A--Y).sub.n n n wherein n R' is halogen, a hydrocarbyl group, the group --NR 2 or the group --OR; n x is --O--, --S-- or --NR--; n A is a bivalent hydrocarbyl radical such that X and Y are separated by not more than 3 carbon atoms; n Y is --OR, --SR, --NR 2 , --PR 2 , a pyridyl radical, a quinolyl radical, an isoquinolyl radical, a furyl radical or a tetrahydrofuryl radical; n R is a hydrocarbyl group; n C a is the molecular proportion of component (2) of the catalyst; n f is the number of functional groups in the phosphorus compound which contain O or N, there being at least one such functional group in the phosphorus compound, and n n is 1, 2 or 3. |
