ABSTRACT:
Disclosed are degradable materials including molded products, laminates, foams, nonwoven materials, adhesives, coatings and films, and particularly packaging films. The materials are made using polydioxaneone polymers comprising at least two different dioxaneone-based repeating units. Preferred polymers are polydioxanediones. First repeating units have less carbon atoms in constituent groups extending from the polymer backbone than second repeating units. Physical characteristics and degradation of the materials can be varied by varying the choice and/or relative proportions of first and second repeating units in the poldioxaneone polymers. Methods for preparing polydioxaneone polymers that can be used in the manufacture of the materials are also discussed, as are suitable monomers and methods for preparing such monomers.
