    Abstract: The invention relates to the production of mouldings based on a particulate material as additive and an aqueous binding agent containing an acrylate polymer, the additive being moistened with the binding agent, converted into the desired shape and subsequently dried, characterised in that a binding agent is employed whose binder is an acrylate polymer whose glass transition range is relatively high and which is built up from (A) predominantly methyl methacrylate, (B) a minor amount of (meth)acrylic acid, (C) if desired, a minor amount of an alkyl ester of acrylic acid and (D) if desired, a small amount of other specific polymerisable compounds.

    Abstract: PCT No. PCT/EP97/00768 Sec. 371 Date Aug. 21, 1998 Sec. 102(e) Date Aug. 21, 1998 PCT Filed Feb. 19, 1997 PCT Pub. No. WO97/31059 PCT Pub. Date Aug. 28, 1997A method for forming shaped products by mixing a formaldehyde-free aqueous binder comprising A) a free-radically polymerized polymer containing from 5 to 100% by weight of units derived from an ethylenically unsaturated acid anhydride or from an ethylenically unsaturated dicarboxylic acid whose carboxyl group can form an anhydride group, and B) an alkanolamine having at least two hydroxyl groups, with fibers or chips to form a shaped article, wherein said binder has a property of drying at 50 DEG C. in 72 hours to a film from 0.3 to 1 mm in thickness and, following a subsequent 15 minute cure at 130 DEG C. in air, has a gel content of above 50% by weight, wherein the binder includes less than 0.1% by weight, based on A)+B), of a phosphorus-containing reaction accelerant with fibers or chips.
