    摘要: A process is described for preparing a functionalized EPM or EPDM artificial latex from the EPM or EPDM polymerization reactor without isolating the polymer. The process includes i) post polymerization functionalizing of an EPM or EPDM copolymer, ii) dispersing the functionalized copolymer in water with an appropriate surfactant and iii) removing the solvents. The resulting latex is useful in paper coatings, latex coatings, adhesives, and in impact modifiers.

    摘要: A desiccant regeneration system is disclosed which employs polymerization diluent as regeneration medium for monomer recycle desiccant driers in ethylene-alpha olefin copolymerizations and utilizes existing diluent purification systems (i.e., systems employed in polymerization processes for diluent recycle), thereby avoiding separate regeneration facilities, providing high purity regeneration fluid and allowing regeneration at relatively mild temperatures.
