Highly functionalized ethylene-vinyl acetate emulsion copolymers

   
   

This invention relates to aqueous emulsion copolymers comprising from about 2% to about 20% of ethylene, from about 20% to about 78% of vinyl acetate, and from about 20% to about 60% of a functionalized monomer selected from the group consisting of acid containing monomers, nitrogen containing monoolefinically unsaturated monomers, and hydroxyl containing monomers. The present invention also pertains to methods for making the ethylene vinyl acetate aqueous emulsion copolymers containing high concentrations of functionalized monomers and to ethylene vinyl acetate aqueous emulsion copolymers made by the the novel methods.

Deze uitvinding heeft op waterige emulsiecopolymeren bestaand uit betrekking van ongeveer 2% aan ongeveer 20% van ethyleen, van ongeveer 20% aan ongeveer 78% van vinylacetate, en van ongeveer 20% aan ongeveer 60% van a functionalized monomeer dat uit de groep wordt geselecteerd die uit zuur monomeren bevatten, stikstof monoolefinically onverzadigde monomeren bevatten, en hydroxyl bestaat die monomeren bevatten. De onderhavige uitvinding behoort ook tot methodes om tot de ethyleen vinylacetate te maken de waterige emulsiecopolymeren die hoge concentraties bevatten van monomeren en aan ethyleen vinylacetate waterige emulsiecopolymeren functionalized die door de nieuwe methodes worden gemaakt.
