Abstract

To prepare copolymers of ethylene with vinyl alkylcarboxylates in the presence of initiators which form free radicals, the vinyl esters dissolved in a solvent are fed simultaneously, but separately from the initiators, to the reaction zone. The novel process increases the polymer yield and gives products with better filtration properties.
