  • Process for fractionating polymers
    Patent number: 5030713
    Abstract: An improved process for crystallizing polymer subjected to temperature rising elution fractionation is provided.

  • Carbonylation of allylic ethers to esters
    Patent number: 5004568
    Abstract: A method is disclosed for the production of esters by reaction of an allylic ether with carbon monoxide in the presence of a catalytically effective amount of a Group VIII noble metal catalyst and a Group IB metal halide to obtain esters. The Group IB metal halide is present in an amount sufficient to prevent the catalyst from being converted into a Group VIII metal during the reaction. When the reaction is conducted in the presence of a quaternary ammonium salt the ester may be extracted by solvent extraction to minimize catalyst decomposition caused when extractive distillation is used to separate the ester.
