Process for the production of star-like or comb-like branched aliphatic polyamino compound and curable resin composition

Abstract

A star-like or comb-like branched aliphatic polyamino compound for use as a basic catalyst or a curing agent, as an effective thixotropic agent or viscosity adjusting agent for an aqueous medium, as a component for any one of a coating-forming agent, a sealing agent, a molding material and an adhesive resin, or as a substantially solvent-free coating composition, molding material or adhesive resin. The process for the production of the above compound comprises (a) forming an adduct of ammonia or an aliphatic amino compound having an amino group (compound A) with methyl acrylate, adding an alkylenediamine having 2 to 12 carbon atoms to the adduct to carry out an ester-amide exchange reaction (b), thereby obtaining a polyamino compound (B) having a total of 2 to 100 aliphatic primary amino and secondary amino groups per molecule and having a number average molecular weight of 170 to 10,000, and forming an adduct of the polyamino compound (B) with an acrylic acid ester (C) of the formula (1), CH.sub.2 =CHCOO--R.sub.1 (1) wherein R.sub.1 is an alkyl group having 4 to 50 carbon atoms or a group of (C.sub.n H.sub.2n O).sub.m R.sub.2 in which R.sub.2 is an alkyl group having 1 to 5 carbon atoms, n is an integer of 1 to 3 and m is an integer of 1 to 25.
