ABSTRACT:
Poly(alkylene carbonate) monoahls and polyahls useful as nonionic surfactants and having a poly(alkylene carbonate) backbone are prepared by reacting an oligomeric poly(alkylene carbonate) polyahl with a compound having mono- or difunctional active hydrogen moieties, such as alcohols, carboxylic acids, mercaptans, amides, primary or secondary amines, or substituted phenols, optionally in the presence of a catalyst, under transesterification conditions.
