Abstract: An impactor head (10) for releasably holding an outer surface (12) of a cup implant (14), comprises a head body (16), at least one rotatable implant-engagement arm (20) which is also at least in part linearly translatable, and an actuation mechanism (18) which moves the implant-engagement arm (20) to an implant-engagement condition and an implant-release condition.

Abstract: The invention relates to a method for the production of a granulate containing at least one polyvinyl acetal, wherein a composition containing a polyvinyl acetal is transformed into molten state and granulated in accordance with the desired grain size. The invention also relates to a granulate produced according to said method and to the utilization of the inventive granulate.

Abstract: The invention relates to high-molecular, crosslinked polyvinyl butyrals, obtainable by (self-) crosslinking polyvinyl butyrals that contain coacetalated, acid-functionalized aldehydes. The invention also relates to a method for producing the same and to the use thereof.

Abstract: The invention relates to a cross-linked polyvinyl acetal which is characterized in that it can be obtained from at least one polyvinylacetal (1) which is obtained by reacting at least one polymer (A), which contains a) 1,0 to 99.9 wt. % structural units of formula (1), b.) 0 to 99.0 wt. % structural units of formula (2), c.) 0 to 70.0 wt. % structural formula (3), d.) 0.0001 to 30.0 wt. % structural units of formula (4) respectively in relation to the overall weight of the polymer (A), with at least one compound (B) of formula (5). Furthermore, the present invention relates to methods for the production of the polyvinyl acetal according to the invention as well as its use.

Abstract: The invention relates to plastic moulded bodies comprising a substrate layer, a barrier layer and a cover layer. The barrier layer contains polyvinyl alcohol. Said plastic moulded bodies are characterised in that the cover layer comprises compounds which can be cross-linked. The invention also relates to plastic moulded bodies comprising a cross-linked cover layer, a method for the production of the inventive plastic moulded body and the use thereof.

Abstract: The invention provides a novel polyvinyl acetal having N-vinylamide monomer units in the molecule, and provides a binder with the novel polymer for ink or paint and for ceramic forming. Compared with conventional polyvinyl acetals, the novel polymer lowers the solution viscosity and increases the solid content (pigment content) of ink or paint in which the polymer serves as a binder. The binder with the novel polymer for ceramic molding enables production of thin and homogeneous ceramic green sheets of high strength.
