  Aromatic solvent-soluble linear oligomers or homopolymers of meta- or para-isopropenyl-a,a-dimethylbenzyl- isocyanate characterized by high isocyanate content are disclosed. Such oligomers or homopolymers are made by catalytic solution polymerization of the monomer in methylene chloride and/or toluene solution at a temperature of from about -80°C to about -25°C, followed by low- temperature neutralization of the polymerization catalyst.

  A method to assemble (Z)-enyne esters via palladium-catalyzed cross coupling reactions of enol tosylates is reported. A base-mediated one-pot decarboxylative rearrangement of the enynes to enones is described. The scope of this process is examined. (c) 2007 Elsevier Ltd. All rights reserved.

  A process to remove metal contaminants from a hydrocarbon solution of polyethylene is disclosed. The process comprises adding a primary alcohol and a ß-diketone to a solution of polyethylene at a temperature within the range of 120°C to 300°C and contacting the solution with basic alumina. The process removes metal contaminants and minimizes degradation and condensation products, which can have a detrimental effect on polyethylene properties. The process provides polyethylene with low metal residues and good properties.
