The present invention relates to the invention of a masticating agent for the mastication of natural and synthetic rubbers, wherein the masticating agent is a dialkyl polysulfide, which is toxicologically acceptable and has very good masticating properties.

Use of dialkyl polysulfides for mastication of natural and synthetic rubbers

The rubber compounds according to the present invention are based on uncrosslinked rubbers, crosslinked rubber particles together with multifunctional isocyanates and polyols. These rubber compounds can be used for the manufacture of rubber vulcanizates or any type of molded rubber article, whereby the vulcanizates display good mechanical properties combined with a large difference in impact resilience values at 70&#xb0; C. and 23&#xb0; C.

Gel-containing rubber compounds with multifunctional isocyanates and polyols

The invention relates to rubber compounds based on rubber particles and phosphoryl polysulfides, as well as to vulcanizates or shaped articles prepared therefrom. The addition of phosphoryl polysulfides improves the strengthening effect of the rubber particles and the level of the mechanical properties, without lowering the resilience of the vulcanizates prepared therefrom.

Microgel-containing rubber compounds with phosphoryl polysulfides and vulcanizates or shaped articles prepared therefrom

This invention relates to a process for the production of dithiophosphoric acid poly-sulfide mixtures, which is characterized in that dithiophosphoric acid disulfides are reacted with sulfur at elevated temperatures. The dithiophosphoric acid polysulfide mixtures produced using the process according to the present invention are used as sulfur donors for the vulcanization of natural and synthetic rubbers and in the latex vulcanization of natural and synthetic rubber latex.

Process for the production of dithiophosphoric acid polysulfide mixtures

The present invention relates to vulcanizable rubber mixes which, apart from the rubbers, contain O,O-bis-(alkyl)-dithiophosphoric acid polysulfides and primary and/or secondary amines, which are characterized in that they may be vulcanized without release of nitrosamines with a high crosslink density and a high proportion of short sulfur bridges.

Vulcanizable rubber mixes

The present invention relates to a catalyst system for the production of polyurethane comprising catalysts for polyurethane formation and sterically hindered carbodiimides, which system is capable of lessening the &ldquo;fogging&rdquo; problem in the production of polyurethane materials, without impairing in particular the aging properties of the polyurethane materials thus produced.
