An aqueous polymer latex composition is described for the preparation of an elastomeric film comprising:

Polymer latex composition for the preparation of an elastomeric film having self-healing properties

The present invention relates to self-supported elastomeric film made from a composition comprising polymer latex particles bearing ethylenically unsaturated groups pending from the polymeric backbone of the latex particles wherein the ethylenic unsaturation is separated from the polymeric backbone by at least 3 chemical bonds, to an article comprising the self-supported elastomeric film and to a method for making a self-supported elastomeric film from a composition comprising said polymer latex particles.

Self-supported elastomeric film having self-healing properties made from a polymer latex

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.

Polymer latex and elastomeric film made therefrom having self-healing properties

The present invention relates to a polymer latex for dip-molding applications obtainable by free-radical emulsion polymerization of a mixture of ethylenically unsaturated monomers comprising at least one conjugated diene and at least one ethylenically unsaturated nitrile compound in an aqueous medium in presence of seed latex particles having a glass transition temperature (mid point temperature Tmg) measured by DSC according to ASTM D3418-03 of −50° C. to 50° C. wherein the seed latex particles do not contain structural units derived from ethylenically unsaturated nitrile compounds, to a method of preparing said polymer latex, to articles made by using said polymer latex and to a method for preparing dip-molded articles from said polymer latex.
