Abstract: N-(2-hydroxyalkanoyl)-N,N?-dialkylureas of general formula (1) are described A-X-(A)m??(1) 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=ā(CH2)nā, 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.
