Patent
CA 1334104
The present invention relates to novel aminophenoxy- and hydroxyl-terminated compounds of the general formula Image wherein R1 is the residue of an m-functional polyhydroxyl compound; R2 is hydrogen or methyl; m is an integer of from 2 to 4, and n is a positive number having an average value of from about 0.05m to about 0.73m. The present invention also relates to a process for the preparation of such compounds comprising reacting in the presence of an alkaline compound (i) an m-functional relatively high molecular weight polyhydroxyl compound with (ii) an n-molar quantity of a halonitrobenzene to form a hydroxy nitrophenoxy adduct, which is then hydrogenated to the corresponding amine. The invention further relates to the use of the compounds of the invention as synthesis component in the preparation of polyurethane plastics by the isocyanate polyaddition process.
