Abstract
Disclosed are degradable materials which-include a nontoxic hydrolytically degradable polymer and nontoxic modifier, wherein the modifier is compatible with the polymer and the modifier is nonvolatile and nonfugitive. Also disclosed are processes for forming the various degradable materials, which include films, molded products, laminates, foams, powders, nonwovens, adhesives and coatings. The disclosed materials and processes are particularly useful for the production of commercial and consumer products in high volumes which are suitable for recycling after use or which are discarded into the environment in large volumes.
