N-(2-HYDROXYALKANOYL) -N,N'-DIALKYLUREAS AND A PROCESS FOR THEIR PREPARATION

摘要

N-(2-hydroxyalkanoyl) -N, N' -dialkylureas of general formula (I) are described A-X-(A)_n, where A: m = 0 or m = 1; when m = 0, X = R''', where R''' is an aliphatic, cycloaliphatic, arylaliphatic radical, C₁-C₁₈; when m = 1, X = -(CH₂)_n-, where n is an integer from 1 and 20, preferably from 2 to 6; R is chosen among H, and alkyl radicals C₁-C₈, possibly substituted with halogen atoms; R' is an aliphatic, cycloaliphatic, arylaliphatic radical, C₁-C₁₈; R'' is chosen among H, aliphatic, cycloaliphatic, arylaliphatic radical, C₁-C₁₈. The preparation of said compounds is described, as well as the preparation of corresponding polymers.
