Patent ID: 7879925

Claim:
A polymeric composite material comprising: a) a polymeric blend that includes: 1) at least one thermoplastic polymer that includes ethylene, propylene, a copolymer including one or both of ethylene or propylene, a derivative or one or both of ethylene or propylene, a blend or one or both of ethylene or propylene, or any combination thereof; 2) at least one functionalized polymer that includes at least one functionality selected from a reactive amino group, a reactive anhydride group, a reactive epoxide group, a reactive carboxylic acid group, a reactive isocyanate group, any derivative of the foregoing, or any combination thereof; 3) at least one polyetheramine thermoplastic material in an amount up to about 3 to about 70 weight percent of the composite material; and b) a plurality of articles of naturally occurring organic materials distributed substantially homogeneously throughout the polymeric blend, the plurality of particles being present in an amount of at least about 20 weight percent of the composite material; wherein the weight ratio of polyetheramine thermoplastic material to the total of the at least one thermoplastic polymer and the at least one functionalized polymer is about 1:20 to about 20:1; and wherein the weight ratio of the at least one functionalized polymer to the at least one polyetheramine thermoplastic material is about 1:40 to about 50:1.
