Abstract:
A process for forming particulate materials and binders into products that are recyclable and/or reusable after comminution, comprising treating particulate materials with a binder composition containingA) one or more copolymers containing one or more comonomer units selected from the group consisting of vinyl esters of branched or unbranched alkyl carboxylic acids of 1 to 18 carbon atoms, acrylic or methacrylic esters of branched or unbranched alcohols of 1 to 15 carbon atoms, dienes, olefins, vinyl aromatics and vinyl halides, and further containing 4 to 60% by weight, based on the total weight of the copolymer(s), of one or more units containing polar groups, and B) 4 to 25% by weight, based on the total weight of copolymer(s) and filler, of one or more fillers having a polar surface capable of interaction with the polar groups of copolymer A), to form treated particulate materials, and consolidating said treated particulate materials into a formed product.
