Abstract
The present invention relates to methods for reprocessing elastomeric films or articles comprising an elastomer film wherein the elastomeric film is made from a polymer latex comprising: (a) particles of a carboxylated conjugated diene nitrile latex polymer (a) obtainable by free-radical emulsion polymerization of a mixture of ethylenically unsaturated monomers comprising conjugated dienes; monomers selected from ethylenically unsaturated nitrile compounds; ethylenically unsaturated carboxylic acids and/or salts thereof; optionally vinyl aromatic monomers; and optionally alkyl esters of ethylenically unsaturated acids, in combination or association with (b) particles of a latex polymer (b) comprising at least one oxirane-functional group; wherein the monomer composition of the latex polymer (a) is different from the monomer composition of the latex polymer (b) and to the use of the polymer latex to make an elastomeric film obtained from the polymer latex self-healing, repairable and/or recyclable.
