Compounds are prepared having the formula Z--Alk--S.sub.x --Alk Z I wherein Z is ##STR1## where R.sup.1 is an alkyl group of 1 to 4 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms or phenyl, R.sup.2 is an alkoxy group of 1 to 8 carbon atoms, a cycloalkoxy group of 5 to 8 carbon atoms or phenoxy, Alk is a divalent hydrocarbon chain of 1 to 10 carbon atoms which can be interrupted with one or two --O--, --S-- or --NH group, and X is a number of 2 to 6 by reacting a compound having the formula Ii. z--alk--SH with sulfur. Some of the compounds are novel and some are old, e.g., in Meyer-Simon U.S. Pat. No. 3,842,111. The compounds are useful as bonding agents in sulfur vulcanizable rubbers.
制备具有公式Z--Alk--S.sub.x --Alk Z I的化合物,其中Z是##STR1##其中R.sup.1是1到4个碳原子的烷基基团,具有5到8个碳原子的环烷基基团或苯基,R.sup.2是1到8个碳原子的烷氧基,具有5到8个碳原子的环烷氧基团或苯氧基,Alk是1到10个碳原子的二价碳氢链,可以被一个或两个--O--,--S--或--NH基团中断,X是通过将具有公式Ii的化合物与硫反应得到的2到6的数字。其中一些化合物是新的,一些是旧的,例如在Meyer-Simon美国专利号3,842,111中。这些化合物在硫硫化橡胶中作为粘接剂是有用的。
