    Abstract: The present invention relates to a novel process for coating objects by means of direct current, in which process an adjustable DC voltage is pulse-modulated with an adjustable AC voltage. The process is useful for electrochemical coating of objects with resinous coating material. Preferably, the pulse modulation of the DC voltage is limited to certain time intervals during the coating process and the pulse modulation is connected and disconnected with an adjustable duty ratio.

    Abstract: The invention relates to a process for the preparation of copolymer in a continuous mode of operation in a polymerization apparatus, comprising a polymerization reactor having feed lines and an outflow, free radical polymerization initiator, an acid monomer and polyether macromonomer being passed as monomeric starting materials into the polymerization reactor through the feed lines, initiator, monomeric starting materials and copolymer-containing reaction composition thermostated at −20 to +120° C. being present in the polymerization reactor, copolymer-containing reaction composition being discharged from the polymerization reactor through the outflow, the introduction of the polyether macromonomer into the polymerization reactor being effected separately from the acid monomer in a manner such that the polyether macromonomer is mixed with the initiator, monomeric starting materials and copolymer-containing reaction composition in the polymerization reactor and comes into contact with the acid monomer for the first time thereby.
