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.
Claims41
A method of carrying out a reactive extrusion process, said method comprising:
- 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.
A method of carrying out a reactive extrusion process, said method comprising:
- combining at least one first reactive component, at least one second reactive component, and a carbon dioxide containing fluid in an extruder to form a mixture such that the carbon dioxide containing fluid comes into intimate contact with the at least one first reactive component and the at least one second reactive component to assist in a reaction between the at least one first reactive component and the at least one second reactive component, and wherein the at least one first reactive component and the at least one second reactive component react and form a product therefrom.
