The present invention relates to rubber mixtures with improved processing behavior and high filler activity, containing 1,4-butenediol and/or 1,4-butenediol polyether, as well as the use of the rubber mixtures for the production of vulcanizates, in particular for the production of highly reinforced, abrasion-resistant molded articles, and preferably for the production of tires that have a low rolling resistance and a high abrasion resistance.
摘要:
The present invention relates to rubber mixtures containing diene rubber with a concentration of primary hydroxyl groups of 0.1 to 2 wt. % and a glass transition temperature of −120° to −50° C. and their mixtures with fillers, optionally further rubbers and rubber auxiliary substances and vulcanisates prepared therefrom. Rubber mixtures according to the invention are suitable for producing highly reinforced, abrasion-resistant moulded items, in particular for producing tires treads which have a particularly high resistance to wet skidding.

摘要:
The present invention relates to rubber mixtures consisting of at least one rubber and a specific proportion of a distillation residue from industrial trimethylolpropane production and the use of the rubber mixtures for the production of vulcanisates, especially for the production of highly reinforced, abrasion-resistant mouldings, particularly preferably for the production of tyres exhibiting low rolling resistance and high abrasion resistance.
摘要:
The invention relates to a process for producing immobilized polysulphide silanes, characterized by the conversion of a halogenated alkyl silane (A), optionally in the presence of a further organic halogen compound (B), with a polysulphide (C) in the presence of water and an inorganic or organic carrier material, wherein the content of the carrier material in the (dried and water-insoluble) end product is 20 to 99.5 wt. %. The immobilized polysulphide silanes are used for producing rubber mixtures and vulcanisates, particularly for tires, which have a low rolling resistance and an enhanced thermal load capacity.
