Abstract
Process for obtaining polyisocyanates of the general formula: A [- 0 - 00 - (0)n - r - nco]m Where m represents an integer from 2 to 10 and n represents 0 or 1, a means a m-valent moiety, free of hydrogen atoms according to zerewitinow with a molecular weight of 500 to 18,000, as obtained by elimination of the hydroxyl groups of a free polymer bearing hydroxyl groups, and r means an aliphatic or cycloaliphatic, divalent hydrocarbon radical having 1 to 20 carbon atoms, characterized in that hydroxyl compounds of the general formula: A[oh]m They are reacted with isocyanates of the general formula; Hal - co - (0) n - r - nc0 Wherein hal means chlorine, bromine or iodine, in the presence of a quantity of halogen-hydrogen absorber at least equivalent to the amount of the isocyanate, if appropriate in the presence of an indifferent organic solvent.
