モノおよびポリアスパルテートの製造方法
Document Type and Number:
Japanese Patent JP4173567
Kind Code:
B2
Abstract:
A process for the production of secondary, mono- and polyamines of formula (I), comprises the reaction of the corresponding amines XÄNH2Üm (II) with compounds of formula R<1>OOC-CH=CH-COOR<2> (III) at 0-100 degrees C in the presence or absence of solvent and with an equivalent ratio of (prim. amino groups in II) to (C=C double bond equivs. in III) = (1:2)- (1.5:1), followed by distillation to remove excess starting materials. The process is carried out in presence of 0.1-10 wt% (based on solids content of reaction mixture) of catalyst(s) and colour stabiliser(s) of formula (IV)-(XI) (component C), in which X = m-valent organic residue, optionally with hetero atom(s), obtained by removing prim. amino group(s) from the corresponding (cyclo)aliphatic mono- or polyamine with a mol. wt. of 60-6000, and also containing functional groups which are reactive towards isocyanate (NCO) and/or inert at temperatures up to 100 degrees C; R<1>, R<2> = organic groups; R<3> = 1-24C organic group (optionally with hetero atom(s)), NH2 or H; R<4>-R<6> = organic groups as for R<3> (optionally part of another, optionally common, ring system), NH2 and/or H; m = at least 1. Also claimed is a process for the production of coatings on any substrates with compositions containing (I) in the binder.
