In a thermoplastically processable composition comprising a continuous matrix of a thermoplastic polymer material and fine particles of a vulcanized rubber dispersed in said matrix, the polymer material contains hydrolysable silane groups and is hence cross-linkable by means of water and/or moisture absorption. An article can be formed out of the composition, using conventional thermoforming methods for thermoplastics, and after thermoforming the composition can be transformed to a fully cross-linked state. The composition can be produced by heat-treating a mixture of the thermoplastic polymer material containing hydrolysable silane groups, the rubber in unvulcanized form and a vulcanizing agent for the rubber at a temperature necessary to vulcanize the rubber, while subjecting the mixture to high shear to simultaneously disperse the vulcanized rubber thus produced, in the form of fine particles in the silane-containing thermoplastic polymer material. |
