摘要：
High molecular weight amines having reduced low molecular weight amine contents are obtained by reacting a mixture of (1) a high molecular weight amine and (2) a low molecular weight amine with (3) an isocyanate in quantities such that from 0.5 to 10 equivalents of isocyanate are present for each equivalent of low molecular weight amine. The product of high molecular weight amines is particularly useful in the production of isocyanate addition products such as polyurethane plastics and foams.
