METHOD FOR REPAIRING OR RECYCLING AN ELASTOMERIC FILM
20220194033 · 2022-06-23 ·

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: 15 to 99 wt.-% of conjugated dienes; 1 to 80 wt.-% of monomers selected from ethylenically unsaturated nitrile compounds; 0.05 to 10 wt.-% of ethylenically unsaturated carboxylic acids and/or salts thereof; 0 to 50 wt.-% of vinyl aromatic monomers; and 0 to 65 wt.-% of alkyl esters of ethylenically unsaturated acids, the weight percentages being based on the total monomers in the mixture 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 said polymer latex to make an elastomeric film obtained from said polymer latex self-healing, repairable and/or recyclable.

Processes and structures for recycling carpet and products of such processes

Methods and equipment for the recycling of carpet are disclosed that produce a clean fiber product suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester, polyolefin, or a polyamide, from carpets that includes a face fiber material, a polypropylene backing material, and an adhesive, and include the steps of mechanically impacting the carpet to break the bonds between the adhesive and the fibrous components, treating the fibrous components to remove adhesive granules from the fibrous components, and optionally separating the polypropylene backing from the face fiber. A clean adhesive/calcium carbonate product can also be produced from this process.
