    Abstract: A metering apparatus for introducing free-flowing, powdered substances in a controlled manner into spaces under pressure consists of a storing unit, a proportioning unit consisting of a shaft which is sealed in a housing with the aid of sealing rings and glands, can be rotated alternately through 180 DEG in each case and is provided with two depressions opposite one another, for accepting and discharging the substance respectively, an end unit consisting of a cylindrical cavity, which is sealed with the aid of sealing rings and glands and has a nozzle-like shape toward the space under pressure, and a spindle which is arranged concentrically with respect to the cavity, is capable of making to and fro stroke-like movements and, at its tip, has a slope corresponding to that of the nozzle-like feed, the end unit being arranged flush with the wall of the space, a connecting line between the storing unit and the accepting depression within the proportioning unit, a connecting line between the discharging depression within the proportioning unit and the cavity of the end unit, and two connections for inert gas.

    Abstract: The invention relates to crosslinkable mixtures comprising 100 parts by weight of an ethylene copolymer containing, per 100 mol of ethylene, from 7.4 to 28 mol of a copolymerised C1- to C8-alkyl (meth)acrylate and from 0 to 10 mol of another ethylene-copolymerisable monomer, and from 0.01 to 4 parts by weight of an organic compound which decomposes to form free radicals at elevated temperature, as crosslinking agent, and to the use thereof for the preparation of moulding compositions of low glass transition temperature and good heat distortion resistance.
