    Abstract: Ionically crosslinked ethylene coolymers prepared by neutralizing the corresponding ethylene copolymers with the addition of an ionomer to a feed zone of an extruder of an ethylene high pressure polymerization system are used for film production, for cable sheathing and as adhesion promoters.

    Abstract: Manufacture of aqueous synthetic wax dispersions which contain as essential component in the solid substance partially or completely neutralised copolymers of C2- to C4-olefins and unsaturated mono- or dicarboxylic acids or dicarboxylic anhydrides, by neutralisation and dispersion of the solid substance in aqueous medium above the melting point of the copolymers, by carrying out the processes of neutralisation and of dispersion in one or more extruders in series.

    Abstract: The invention concerns a process for continuously producing impact-resistant modified thermoplastic moulding compounds which contain a rubber-elastic soft phase dispersed in a vinylaromatic hard matrix. In a first reaction zone the rubber necessary for forming the soft phase is polymerized anionically in solution substantially without re-mixing until the reaction is complete. The rubber is fed, directly or after the addition of a breaking or coupling agent, to a second reaction zone in which it is polymerized until the phases are inverted with the addition of an amount of vinylaromatic monomer sufficient for phase inversion and a further anionic initiator. In a third reaction zone polymerization is terminated anionically with as many vinylaromatic monomers as are required to form the impact-resistant modified thermoplastic moulding compound.

    Abstract: The copolymers comprise from 96 to 99.6 mol% of ethylene and from 0.4 to 4 mol% of a C3-C6-alkenecarboxylic acid or an ester of this acid having a total of up to 14 carbon atoms, or mixtures of these monomers, and are obtainable by polymerisation in a continuous tubular reactor at a pressure of from 500 to 5000 bar and at elevated temperature in the presence of initiators which decompose to form free radicals, by adding a mixture of said reaction components only at the inlet point of the tubular reactor, the temperature in a first reaction zone being limited to about 240 DEG C, further initiator being metered in at the beginning of a second reaction zone after the temperature has been reduced by from 5 to 20 DEG C, and the reaction being completed at temperatures of up to 300 DEG C.
