ABSTRACT:
Methods of carrying out a reactive extrusion processes are described that include combining at least one polymer, oligomer, or combination thereof, a carbon dioxide containing fluid, and at least one reactant in an extruder to form a mixture such that the carbon dioxide containing fluid comes into intimate contact with the at least one polymer, oligomer, or combination thereof and assists in a reaction between the at least one polymer, oligomer, or combination thereof and the at least one reactant, and wherein the at least one polymer, oligomer, or combination thereof is modified upon reaction with the at least one reactant.
