The invention relates to the field of chemistry and to the blends that can by way of example be used for rolls and roll coverings in the printing, textile, paper and graphic industry. The problem addressed by the present invention is provision of blends that have improved physical properties, and of a simple low-cost process with low energy consumption for producing same. The problem is solved via blends of thermoplastic polyurethanes and rubbers, consisting of rubber and from 5 to 80% by weight of thermoplastic polyurethanes, where the materials intermesh with one another in the regions of contact between rubber and polyurethanes. The problem is further solved via a process in which at least one rubber and from 5 to 80% by weight of polyurethane precursors are mixed and homogenized, where the precursors are prepolymers made of polyisocyanate(s) and of macroglyeol(s) and at least one chain extender, and/or monomers of polyisocyanates, of macroglycols and of chain extenders.

The present invention relates to rubber or elastomer compositions as can be used for vehicle tires, and to a method for the production of the rubber or elastomer compositions. The elastic modulus of the compositions can be adapted depending on the temperature and/or the application conditions, and is a cost-effective and easily implemented method for the production of the compositions. The rubber or elastomer compositions contain at least one rubber or elastomer matrix and at least 20 to 150 phr of a phase change material in solid or liquid form. The compositions may be made by mixing the at least one rubber and the at least 20 to 150 phr of a phase change material in solid or liquid form, or the at least one rubber is at least brought into contact with the phase change material, and further processing steps can be performed, and a vulcanization can be performed.

Rubber or elastomer compositions and processes for their manufacturing

An elastomeric composition that has a high tensile strength and high hardness is produced by a method that is cost-efficient and easy to carry out. The object is attained by an elastomeric composition that contains at least one base elastomer, at least one hydrophilic polymer, and at least one inorganic salt. The object is furthermore attained by a method for producing an elastomeric composition in which at least one rubber, at least one hydrophilic polymer and at least one inorganic salt are mixed and subsequently vulcanized, the elastomeric composition is then at least partially brought into contact with water, and afterwards the water is at least partially removed from the elastomeric composition. The elastomeric composition according to the invention can, for example, be used in vehicles and machines as a seal, grommet, disc, coupling or membrane.

Elastomeric composition and process for its preparation

The invention is concerned with the field of polymer chemistry and relates to elastomeric materials as usable, for example, as an inner liner material for motor vehicle tires, and to the use thereof. The problem addressed by the present invention consists in specifying elastomeric materials having relatively low gas permeability. The problem is solved by elastomeric materials comprising butyl and/or halobutyl rubbers or mixtures thereof, with 1 to 20 phr of at least one liquid imidazolium salt and with 1 to 40 phr of at least one filler having a graphitic structure. The problem is additionally solved by the use of the inventive elastomeric materials for elastomer materials having low to very low gas permeability.
