ABSTRACT:
High density ethylene polymers are prepared by polymerizing the monomers in the presence of a Ziegler catalyst system by a process in which the resulting solid ethylene polymer is reacted in the melt with an additive capable of binding acids by esterification. The ester-forming additives are preferably epoxide compounds.
