The invention relates to a composite which is produced by means of 2-component processing methods, preferably 2-component injection moulding (2K injection moulding), from at least one part composed of at least one polyalkenamer-additized polyamide moulding composition and at least one part composed of at least one elastomer obtainable from rubber that is to be vulcanized or crosslinked with elemental sulphur, or is composed of these components after processing thereof, without using an adhesion promoter, wherein the individual parts of the composite are macroscopic mouldings but not, for example, dispersed particles in a polymer/elastomer blend or polyamide fibres in an elastomer matrix, such blends therefore not being composites in the sense of the invention, and to a method for producing such composites, to the use of polyalkenamer for improving the composite adhesion of polyamide-based mouldings with an elastomer component obtainable from rubber that is to be vulcanized or crosslinked with elemental sulphur, and to the use of polyalkenamer for reducing the melting point or softening point of polyamide.
A composite composed of directly adhering parts, wherein at least one part comprises at least one polyamide moulding composition and at least one other comprises at least one elastomer, without any adhesion promoter between the parts, wherein:
A method for lowering the melting point of softening point of a polyamide, the method comprising mixing a polyalkenamer with the polyamide.
A method for producing composites composed of directly adhering parts, wherein at least one part comprises at least one polyamide moulding composition, and at least one other part comprises at least one elastomer comprising at least one rubber that is cross-linkable or vulcanizable with elemental sulphur as crosslinking agent, the method comprising producing the composites by at least one shaping method further comprising:
