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