Process for the polymerization of alpha olefins using a new aluminophosphate support
First Claim
Patent Images
1. A polymerization process comprising:
- contacting at least one mono-1-olefin having from 2 to 8 carbon atoms per molecule inclusive under polymerization reaction conditions in a polymerization reaction zone with a catalyst comprising an active catalytic component on an aluminophosphate support PREPARED FROM AQUEOUS SOLUTIONS OF ALUMINUM AND PHOSPHORUS IONS, and wherein the phosphorous to aluminum mole ratio of said aluminophosphate is less than one, said aluminophosphate being further characterized as (a) amorphous and (b) having, on a microlevel, sheets of aluminophosphate as well as spheres of aluminophosphate, and recovering a polymer.

Abstract
Novel catalysts are provided for the polymerization of olefins such as ethylene. These catalysts comprise a novel amorphous aluminophosphate comprising, on a microlevel, sheets of aluminophosphate as well as spheres of aluminophosphate plus a chromium compound. These new catalysts are surprisingly active; result in more co-monomer incorporation than prior art catalysts and reduce the amount of low molecular weight material in the product.
