A process has been developed for controlling the catalytic co-oligmoerization of 1,3-dienes with Schiff's bases which comprises condensing a 1,3-diene of the formula ##STR1## wherein R.sup.4 and R.sup.5, independently of one another, represent hydrogen or an alkyl group having 1 to 4 carbon atoms with a Schiff base of the formula ##STR2## wherein each of R.sup.1, R.sup.2 and R.sup.3 represents hydrogen alkyl, cycloalkyl, aralkyl, aryl or dimethylamino groups which, in addition, optionally contain functional groups of the group consisting of ethers esters, C.dbd.N double bonds and which can be closed to form a ring, in the presence of a nickel (O)-containing catalyst, and optionally in the presence of an X--H compound with a molar ratio of Ni: X H of from 1:0 to 1:10.
已经开发出一种用于控制1,3-二烯与席夫碱的催化共聚合的过程,包括将式为##STR1##的1,3-二烯与式为##STR2##的席夫碱缩合,其中R.sup.4和R.sup.5分别独立地表示氢或具有1至4个碳原子的烷基基团;每个R.sup.1、R.sup.2和R.sup.3表示氢、烷基、环烷基、芳基烷基、芳基或二甲基氨基基团,此外,还可以选择地包含醚、酯、C.dbd.N双键的官能团,并且可以闭合形成环,在存在含镍(O)的催化剂和可选的X-H化合物的情况下进行,其中Ni:X H的摩尔比为1:0至1:10。
