Abstract: The present invention relates to the use of active coal for reducing odor emissions from aqueous polymer dispersions and products obtained therefrom. It also pertains to aqueous polymer dispersions containing 0.1 to 20 wt.% of active coal, their use as a binder for fibre composites, and the fibre composites themselves.

Abstract: Radically initiated aqueous emulsion polymerisation process giving an aqueous polymer dispersion comprises emulsifying an ethylenically unsaturated group-containing compound(s) in aqueous medium using a dispersing agent and polymerising either using a radical polymerisation initiator in the presence of a stable N-oxyl radical(s) or using a compound(s) which decomposes on heating into a stable N-oxyl radical(s) and a radical polymerisation initiator. The emulsion obtained comprises droplets of diameter at most 500 nm and is polymerised by increasing the temperature. Also claimed are the obtained aqueous polymer dispersions.
