Abstract

Polymeric amines are prepared by (1) reacting HCHO at <50 DEG C with at least one mole per cent of HCHO of aniline or an ortho- or meta-substituted C1-C4 alkyl aniline in the presence of a mineral acid (e.g. HCl), (2) further reacting the product of (1) with 0.15 to 1.2 moles per mole of HCHO of m-phenylene dimine or a 2- or 4- subs. C1-C4 alkyl-m-phenylene diamine at <50 DEG C., (3) heating the product of (2) to at least 60 DEG C. for a time sufficient to complete the reaction. The mole ratio of total amines to HCHO ranges from 1.5: 1 to 4.5: 1. The HCHO may be generated in situ in the reaction mixture, e.g. from paraformaldehyde. The product of (3) may be further reacted with phosgene to yield a polymeric isocyanate.
