ABSTRACT Poly(alkylene carbonate) monoahls and polyahls 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. These monoahls and polyahls are useful as mom-ionic surfactants. The compounds having active hydrogen moieties become bonded to the polyahl backbone to form products having molecular weights between those of the starting materials. The carbonate backbone in the non-ionic surfactants can be degraded by bases, strong acids or biodegradation. Accordingly, they will be degraded naturally and will not persist in the environment. 32,739A-F
