摘要

1436955 Nickel salt; alkanolamine complexes E I DU PONT DE NEMOURS & CO 10 Oct 1973 [11 Oct 1972] 47361/73 Heading C2C Novel complexes of formula and are made by mixing at least two moles of 2-N,N- dimethyaminoethanol with one mole of nickel chloride or nickel thiocyanate in a solvent in which the nickel salt is soluble (e.g. methanol or ethanol) and thereafter evaporating the solvent and any excess amine and recovering the product. The complexes are used as curing agents for chloroprene polymers.
