    IPC: C08F6/00

    Abstract: A process is described for effectively reducing the residual monomer content of an aqueous polymer dispersion by aftertreatment at atmospheric pressure or above with an initiator system comprising a) a hydroperoxide, hydrogen peroxide or a peracid, and b) an alpha-hydroxy carboxylic acid, such as tartaric acid, or with a salt thereof.

    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.
