    Abstract: Aqueous polymer dispersion comprises: (a) dispersed particles of an olefinic copolymer with 5-20 wt.% alpha , beta -unsaturated mono or di-carboxylic acid units, (b) a dissolved polymer containing 60-100 wt.% unsaturated acid units as in (a), and (c) an alkoxylated amine. It is obtained by emulsion polymerisation of unsaturated monomers in presence of (b) and (c). Aqueous polymer dispersion comprises: (a) dispersed particles of a polymer based on ethylenically unsaturated monomer units, containing 5-20 wt.% alpha , beta -unsaturated mono or di-carboxylic acid, (b) a dissolved polymer containing 60-100 wt.% alpha , beta -unsaturated mono or di-carboxylic acid units (or salt), and (c) an amine of formula (I). R = ≥ 6 C alkyl or alkylene (sic) group or an alkylphenyl group with ≥ 6 C atoms in the alkyl part R' = H or 1-4 C alkyl R'' = 1-4 C alkylene m, n, o = ≥ 0 m, n and/or o = ≥ 1 p = 0 or 1 The dispersion shows weight ratios (based on solid contents) of (a):(b) = (7:1)-(1:7) and (b):(c) = (20:1)-(2:1). It is obtained by emulsion polymerisation of unsaturated monomers in presence of dissolved polymer (b) and amine (c). An Independent claim is also included for a two or three-dimensional formed articles obtained by impregnating a particulate or fibrous substrate with the dispersion and hardening the impregnated substrate.

    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.
