Abstract
The present invention is a hydrolytically modified, biodegradable polymer and a method of hydrolytically modifying a biodegradable polymer. In a preferred embodiment, the invention is a method of grafting polar groups onto polylactides and modified polylactide compositions produced by the method. The polymer compositions are useful as components in flushable and degradable articles.
