Abstract
The present invention relates to an aqueous dispersion comprising core-shell polymer latex particles wherein the shell of the core-shell polymer latex particles bears ethylenically unsaturated groups pending from the polymeric backbone of the shell of the latex particles wherein the ethylenic unsaturation is separated from the polymeric backbone by at least 3 chemical bonds and wherein the shell of the core-shell particles is cross-linked and the core of the core-shell particles is not crosslinked, to a method for making the aqueous dispersion, to an elastomeric film made from the aqueous dispersion, to an article comprising the elastomeric film and to a method for making a self-supported elastomeric film from the aqueous dispersion.
