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

A thermally vulcanizable pressure-sensitive adhesive comprising a chemically precrosslinked, pressure-sensitively adhesive polybutadiene-polyurethane and ground sulfur, which during the heating phase remains pressure-sensitively adhesive, does not liquefy and hence in this phase, in which the vulcanization has not yet started and the curing has not yet commenced, has shear strength at least under load to moderate low, is able to transmit forces and hence to perform holding, a process for producing it, an adhesive tape comprising this pressure-sensitive adhesive, and a process for producing the adhesive tape.

Thermally vulcanizable adhesive tape with shear strength during the heating and curing phase
