    摘要: A vinyl polymer is obtainable by polymerizing vinyl monomers in at least two stages by a procedure in which, in a first stage, from 5 to 95% by weight of vinyl monomers are polymerized in an organic solvent or in the absence of a solvent and, in the second stage, from 5 to 95% by weight of the vinyl monomers are polymerized in the presence of the vinyl polymer obtained in the first stage, likewise in an organic solvent or in the absence of a solvent, with the proviso that the polymerization in the second stage is carried out under conditions under which an average molecular weight M.sub.n, which is at least 1,000 higher compared with that of the vinyl polymer, the first stage of results for the vinyl monomers of the second stage in the absence of the vinyl polymer obtained in the first stage.

    摘要: The invention relates to a hydraulic drive, especially for two-cylinder thick matter pumps. Said hydraulic drive comprises at least one main pump (10) embodied as a hydraulic variable displacement pump, and two hydraulically actuatable drive cylinders (20,22) that are each connected to a connection line (16,18) of the main pump (10) by means of pump connections mounted on one end thereof, forming a closed hydraulic circuit, and communicate with each other at the ends thereof opposing the pump connections (24,26) by means of a swinging oil line (28). The hydraulic drive also comprises a feed pump (42), by which means pressurized oil is fed from an oil tank to the current low-pressure side into the hydraulic circuit, and a flushing branch (52), by which means a flushing oil flow is branched off from the current low-pressure side under a limited pressure into the oil tank (44). In order to avoid low-pressure influxes during the reversal process of the main pump (10), the flushing oil flow is blocked and then released in a time-delayed manner during each reversal process of the main pump (10), independently of the differential pressure in the connection lines.
