Abstract: A manipulator for components, in particular sheet metal parts, includes a base body mountable stationarily or movable along a guide arrangement, a first pivot arm pivotally coupled to the base body via a horizontal first pivot axis, a second pivot arm pivotally coupled to the first pivot arm via a horizontal second pivot axis and a third pivot arm pivotally coupled to the second pivot arm via a horizontal third pivot axis. A first axis of rotation extending radially to the third pivot axis is formed on the third pivot arm. A gripper support arm is rotatably coupled to the third pivot arm via the first axis of rotation and extends radially to the first axis of rotation. A gripping arrangement is rotatably coupled to the gripper support arm via a second axis of rotation spaced from the first axis of rotation. A bending installation includes the manipulator.

Abstract: Methods for preparing vinyl ester-ethylene copolymers and methods for recovering residual monomers when preparing the same. The method includes performing a stage (a) where radically initiated polymerization of vinyl esters, ethylene and optionally further ethylenically unsaturated monomers in an aqueous medium is performed. In a stage (b) a polymerization mixture from stage (a) is depressurized producing an ethylene-containing gas phase and an aqueous phase containing vinyl esters and vinyl ester-ethylene copolymers. Where the ethylene-containing gas phase separated off, then absorbed into vinyl esters and the mixture thus obtained is used in the radically initiated polymerization of vinyl esters, ethylene and optionally further ethylenically unsaturated monomers.

Abstract: A process for preparing vinyl acetate-ethylene copolymers in the form of an aqueous dispersion. The process includes providing an aqueous dispersion of vinyl acetate-ethylene copolymers and subjecting the aqueous dispersion of vinyl acetate-ethylene copolymers to radically initiated emulsion polymerization in a continuously operated tubular-reactor. Where one or more dividing plates bearing liquid-permeable openings that are mounted within the tubular-reactor transverse to the flow direction of the reactor contents.
