An autohesive polymer material that includes: at least one polymer having at least two terminal silyl groups of the Formula (1) given by:Si(R)(R)&#x2003;&#x2003;(1).Each of the radicals Rcomprises an alkyl, alkenyl or aryl group or a hydrogen atom. Each of the radicals Rcomprises a group that can be eliminated with water, b is 1, 2 or 3, and a is 3&#x2212;b. The polymer material further includes at least one condensation catalyst. Further, the polymer material is chemically precrosslinked and further crosslinkable with moisture. In addition, the polymer material is configured for use as a layer body that can be applied to a substrate. The polymer material of this kind can also be used for producing permanent bonds.

Moisture-crosslinkable, dimensionally stable polymer material

Method for uniform coating of a composition onto a carrier material in web form, through the use of a coating apparatus comprising at least one element A, that forms with a further element B a nip ahead of which the composition is held up, and that moves relative to the element B in such a way that a rotating body of composition is developed and the composition is conveyed into the nip; comprising introduction of the composition into the intake region of the nip, the application of the composition to a carrier material in web form in the nip or after the composition has travelled through the nip, and which limits the longitudinal extent E of the nip intake region fully fillable by the body of composition.

Side-feed coating method

The invention relates to a process for preparing homogeneously crosslinked polymers, in which at least one crosslinker is added to a polymer in the melt, in which the polymer is further processed from the melt, and in which a thermal crosslinking reaction is brought about by means of the crosslinker, with at least part of the crosslinking reaction taking place after the further processing at a temperature below the melting temperature of the polymer, characterized in that the crosslinker comprises an at least difunctional compound, at least one of the functional groups being an oxazoline group, and the polymer contains functional groups which, at a temperature below the melting temperature of the polymer, are able to react with the oxazolines in a linking reaction in the sense of the thermal crosslinking reaction.

Thermally crosslinking polyacrylates and process for their preparation

Apparatus far equilibrating differences between flow rates into and out of closed pipeline systems, which apparatus includes a tank having a supply line and a discharge unit, with a displaceable plate; the supply being fed to the tank through the displaceable plate, the discharge from the tank being through an outlet at the bottom of the tank and the plate moving upwards or downwards to automatically change the volume of the tank in accordance with differences between the supply rate and the discharge rate.
