Abstract: A method is disclosed for separating impurity components, UV absorbers and/or UV absorber precursors contained in an ethylene glycol-water stream thereby desirably allowing the recovery of the glycols contained in such stream in an economical and efficient manner. Specifically, these undesirable components are separated by contacting the ethylene glycol-water stream with a suitable semi-permeable membrane to effect such separation.

IPC: C08F04/68
Abstract: An improved support vanadium catalyst, especially an improved Beran et al. catalyst system and ethylene polymerization process in which the improvement derives from fixing the promoter to a component of the catalyst composition such that it is a molecularly structural component of the catalyst and thus is not separately fed to the polymerization reaction, but instead is part of the catalyst composition fed to the reaction.
