摘要:
The present invention relates to novel polysulfides mixtures comprising compounds of the formula (I) where n is from 2 to 6, and R is C1-C8-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.
摘要:
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.
摘要:
The present invention relates to polysulfide mixtures comprising two or more compounds of the formula (I), where the cations K1+ and K2+ mutually independently are any desired monovalent or are the nth part of an n-valent cation, and m is 0, 1, and/or 2, to a process for the production of these polysulfide mixtures, to the use of the polysulfide mixtures in rubber mixtures, to the rubber mixtures, to rubber vulcanizates produced therefrom, and to the use of these.
摘要:
The present invention relates to rubber mixtures comprising respectively at least one rubber, one sulfur-containing alkoxysilane, one silicon-based filler, and one ω-mercaptocarboxylic ester of polyhydric alcohols.
摘要:
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—(S)x—S—Y—S—(S)x—S-A (I) where x is 0, 1 or 2, Y is an aliphatic, cycloaliphatic or aromatic group that is optionally substituted or else comprises heteroatoms and A is an optionally substituted hydroxyethyl, carboxyaryl, hydroxyaryl, carboxyalkyl or thionamide moiety, and comprises from 0.1 to 15 parts by weight, based on 100 parts by weight of rubber used, of 1,6-bis(N,N-dibenzylthiocarbamoyldithio)hexane (CAS No.: 151900-44-6).
摘要:
The invention relates to processing additive mixtures comprising at least one polyol, amide and/or carboxylic acid, optionally auxiliaries for crystallization and at least one organic ammonium salt. Said processing additive mixtures allow the optimization of the vulcanization behavior of rubber mixtures and the properties of vulcanizates obtained by said vulcanization.
