The invention relates to substantially diphenylguanidine-free rubber mixtures comprising at least one rubber, one silica-based filler and/or carbon black and short-chain alkyl esters of glycerol, production of these, use and vulcanizates thus obtainable.

Diphenylguanidine-free rubber mixtures containing short-chain alkyl esters of glycerin

Vulcanizable polymer compositions based on backbone-functionalized polydienes having the general formula (I): 

Functionalized polymer composition

The present invention relates to a silica-containing rubber mixture produced from at least one rubber, one sulphur-containing alkoxysilane, one crosslinking agent, one filler, and optionally further rubber auxiliary products and from 0.1 to 15 phr of a polysulphide additive of the formula (I)A-S&#x2014;(S)&#x2014;S&#x2014;Y&#x2014;S&#x2014;(S)&#x2014;S-A&#x2003;&#x2003;(I)where x is 0, 1 or 2,

Rubber blends containing silicic acid and comprising additives containing sulphur

The present invention relates to novel polysulfides mixtures comprising compounds of the formula (I) where n is from 2 to 6, and R is C-C-alkyl, to processes for the production of said polysulfides mixtures, to use of these for the production of rubber matures, and to rubber vulcanizates produced therefrom.

Polysulfide mixtures, method for the production thereof, and use of the polysulfide mixtures in rubber mixtures

The present invention relates to rubber mixtures comprising respectively at least one rubber, one sulfur-containing alkoxysilane, one silicon-based filler, and one &#x3c9;-mercaptocarboxylic ester of polyhydric alcohols.

Siliceous rubber mixtures containing omega-mercaptocarboxylic acid ester of polyvalent alcohols

The invention relates to rubber mixtures comprising at least in each case one nonpolar rubber, carbon black, and short-chain alkyl esters of glycerol, production of these, use, and the vulcanizates thus obtainable.

Rubber mixtures containing short-chain alkyl esters of glycerin

The present invention relates to a silica-containing rubber mixture produced from at least one rubber, one sulphur-containing alkoxysilane, one crosslinking agent, one filler, and optionally further rubber auxiliary products, wherein this mixture comprises from 0.1 to 15 parts by weight, based on 100 parts by weight of rubber used, of a polysulphide additive of the formula (I)A-S&#x2014;(S)&#x2014;S&#x2014;B&#x2003;&#x2003;(I)

The present invention relates to a process for producing rubber mixtures in a mixing process with, for example, a plurality of mixing stages, where these can optionally be divided into a plurality of sub-steps, comprising the mixing of the following components:

Method for producing rubber mixtures

A process for processing a feedstock comprising a major amount of olefinic hydrocarbons having 4 carbon atoms per molecule, including isobutene as well as but-1-ene and but-2-enes, wherein the process comprises processing said feedstock in a distillation zone associated with a hydroisomerization reaction zone located at least partly external to the distillation zone, said processing comprising drawing at the height of a draw-off level of the distillation zone at least part of the liquid flowing in the distillation zone, passing said liquid into the external hydroisomerization reaction zone to form a hydroisomerized effluent, and reintroducing at least part of the effluent from said reaction zone reintroduced into the distillation zone at one or more reintroduction level(s), so as to ensure the continuity of the distillation.
