A novel vulcanizable polymer composition is provided which is characterized by a specific combination of a polyamine crosslinking agent and a particular crosslinking accelerator. Furtheron polymer vulcanizates on the basis of such polymer compositions as well as method for preparing such polymer vulcanizate is provided, in particular in the form of mouldings or shaped parts.

Vulcanizable polymer compositions

Polymer vulcanizate and process for the production thereof

The present invention relates to a solar module containing at least one layer made up of at least one &#x3b1;-olefin-vinyl acetate copolymer which has a vinyl acetate content of &#x2267;40% by weight, based on the total weight of the &#x3b1;-olefin-vinyl acetate copolymer, and has been prepared by a solution polymerization process at a pressure of from 100 to 700 bar, the use of the &#x3b1;-olefin-vinyl acetate copolymer mentioned in solar modules, the use of the solar module of the invention for stationary or mobile power generation and also a solar power plant containing at least one solar module according to the invention.

Novel crosslinkable compositions based on elastomers, at least one of which has carboxyl and/or carboxylate groups, are provided, these crosslinkable compositions containing special unsaturated organic salts of metal ions and a crosslinking system which acts as a free radical donor. Crosslinked elastomers which have excellent physical properties are obtainable therefrom. The novel crosslinkable compositions have a wide range of uses.

Crosslinkable compositions, processes for the preparation thereof and the use thereof

The present invention relates to hydrogenated carboxylated nitrile-butadiene rubber (HXNBR), which contain molecularly dispersed triphenylphosphine, and which is useful as a cross-linking agent for elastomers, plastics and/or adhesive systems. The present invention also relates to products which are obtainable from the HXNBR having molecularly dispersed triphenylphosphine and elastomer, plastics and/or adhesive systems, a composition containing a HXNBR having molecularly dispersed triphenylphosphine and further non-molecularly dispersed activators, a process for the preparation of the composition as well as the use of HXNBR having molecularly dispersed triphenylphosphine, as an elasticizing agent for elastomer, plastics and/or adhesive systems.

HXNBR-rubber as a cross-linking agent

The rubber mixtures according to the present invention consisting of uncrosslinked, double bond-containing rubbers (A), crosslinked rubber particles (B) and multifunctional isocyanates based on polyuret (C), wherein, based on 100 parts by weight (phr) of the rubber components (A) respectively, the component (B) content in the mixture is 1 to 150 parts by weight and the multifunctional isocyanate content based on polyuret (component C) is 1 to 100 parts by weight, can be used to produce rubber vulcanizates and rubber molded articles of all kinds, the vulcanizates produced therefrom exhibiting an advantageous combination of mechanical properties, such as modulus at 300% elongation, elongation at break, tear strength and abrasion resistance.

Rubber mixtures based on uncrosslinked rubbers and crosslinked rubber particles and multifunctional isocyanates based on polyuret

The invention relates to rubber mixtures which contain microgels and isocyanatosilanes and vulcanisates produced therefrom. By adding isocyanatosilanes the mechanical properties of the vulcanisates, in particular the elongation properties and the abrasion resistance, are improved without the difference in rebound resilience at 70&deg; C. and 23&deg; C. being reduced.
