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.

Abstract: A process is disclosed for preparing an aqueous polymer dispersion by radical-initiated polymerisation of radically polymerisable compounds (I) which are moderately water-soluble. Besides the compounds (I), the dispersed polymer particles also contain compounds (II) which are hardly water-soluble. For that purpose, an aqueous emulsion (I) with a droplet size /= 1000 nm.

Abstract: The mixing device comprises a housing (11), a reaction chamber (12) and at least a means for transmission of ultrasound waves (13) that has a free radiating surface (14) in effective contact with the reaction space (12). The area of the free radiating surface (14) is similar to the surface area of the reaction space (12) and/or if the reaction space is a portion of a tubular flow through reactor, extends over the whole width of the channel. The vertical depth (12b) of the reaction space is less than the maximum effective depth of the ultrasound transmitter.

Abstract: Production of aqueous polymer dispersions (APD) by radical-initiated emulsion polymerisation of a mixture of : (I) radically polymerisable organo-silicon compounds which form silanols on hydrolysis with water; and (II) radically polymerisable compounds other than (I). The process comprises using at least part of (I) and at least part of (II) to make an aqueous emulsion in which the disperse phase consists mainly of droplets with a diameter of \}500 nm, then using this emulsion for polymerisation as above. Also claimed are APD obtained by this process.

Abstract: A process is disclosed for emptying hoses filled with viscous masses. A hose containing a viscous mass (E) is clamped in a device which includes a tubular member (A), the hose is conveyed through the tubular member while the hose sheath is slit open in the longitudinal direction, the open hose sheath is separated from the viscous mass, and the viscous mass leaves the device through a discharge opening. A device for carrying out this process includes a tubular member (A) with at least three openings, namely at least one opening for receiving filled hoses, at least one discharge opening and at least one additional opening. One or several slitting devices (F) are mounted between the at least one receiving opening and the at least one additional opening.

Abstract: In the production of aqueous polymer dispersions by free radical emulsion polymerisation of monomers, a mini-emulsion (I) is added before or during polymerisation. (I) is an aqueous emulsion, stabilised with a surfactant, which contains emulsified monomer droplets with a particle size of 10-500 nm and a co-stabiliser, dissolved in the monomer, which is at least twice as soluble in the monomer as it is in water. Also claimed are polymer dispersions obtained in this way.
