A Greedy Randomized Algorithm for the Cooperative Communication Problem on Ad Hoc Networks

Ethylene and alpha-olefins are homopolymerized or copolymerized with another olefin monomer in the presence of a catalyst system comprising an organo metal cocatalyst and a titanium-containing catalyst component, said titanium-containing catalyst component being obtained by reacting together a porous particulate material, an organic magnesium compound, an oxygen containing compound, an acyl halide and titanium tetrachloride and a Group IIIa hydrocarbyl metal dihalide.
