摘要： The invention relates to a device for producing moulded bodies from thermoplastic polymers, starting from monomers that form polymers of this type, in a discontinuous method. Said device comprises a) at least one reactor that is suitable for producing a thermoplastic polymer melt in a discontinuous process starting from monomers that form a polymer of this type, b) a network of pipes that is suitable for circulating the thermoplastic polymer melt and c) at least one device that is suitable for producing moulded bodies from a thermoplastic polymer melt. According to the invention, the reactor or reactors according to a) is/are connected to the network of pipes according to b) and the device or devices according to c) is/are connected to the network of pipes according to b). The invention also relates to a method for producing moulded bodies from thermoplastic polymers in a device of this type.

摘要： The invention relates to a coarse-particle microcapsule preparation containing particles having a particle size of between 200 µm and 5 cm. Said preparation also contains microcapsules having a capsule core consisting of latent heat accumulator material, a duroplastic polymer as a capsule wall, and at least one polymer binding agent, the binding agent polymer thereof having thermoplastic properties in addition to film-forming properties under processing conditions. The binding agent calculated as a solid amounts to between 1 and 30 wt. % in relation to the total weight of the coarse-particle microcapsule preparation.

摘要： The invention relates to defoaming agents that are devoid of emulsifiers, obtained by mixing: a) between 80 and 99 wt. % of at least one fine-particled, practically water-insoluble inert solid with b) between 1 and 20 wt. % of at least one hydrophobic organic compound that is solid at room temperature and has a defoaming action in substance with such a shear gradient that the particle size of the defoaming compounds (b) is reduced to an average particle size of between 0.5 and 15 µm. The invention also relates to a method for producing oil-in-water dispersions that are devoid of emulsifiers from mixtures of (a) and (b). Said method involves the mixing of component (a) in a quantity of between 80 and 99 wt. % with component (b) in a quantity of between 1 and 20 wt % in the absence of emulsifiers in an extruder or kneading machine, in such a way that the average particle size of component (b) in the mixture is regulated to between 0.5 and 15 µm, at temperatures of up to 100 °C and the subsequent emulsification of the mixture in water. The invention further relates to the use of the oil-in-water dispersions obtained by said method as defoaming agents and/or deaerators of aqueous, disperse or non-disperse liquids, in particular as defoaming agents and/or deaerators in the paper industry, in the foodstuff industry and in purification plants.
