Abstract
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.
