Abstract: An improved process for crystallizing polymer subjected to temperature rising elution fractionation is provided. The process improves the separation of the polymer species upon elution and significantly reduces "tailing" typically observed with such fractionated species. The improvements consists of crystallizing the polymer from a dilute polymer solution outside of the column and in the absence of column packing material. Only after crystallization is the polymer combined with the column packing material. This can be accomplished by either dry-blending or by slurrying.

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.
