Abstract:
A method of making a polymer blend comprising the steps of:a) combining a first biodegradable polymer, a second biodegradable polymer, a polar monomer, oligomer, or polymer or a combination thereof and a free radical initiator in a reaction vessel; and b) providing sufficient energy to the combination of said first and second biodegradable polymers, said polar monomer, oligomer, or polymer or a combination thereof and said free radical initiator in order to form a blend of a first biodegradable polymer grafted with a polar monomer, oligomer, or polymer or a combination thereof and a second biodegradable polymer grafted with a polar monomer, oligomer, or polymer or a combination thereof, wherein said first and second biodegradable polymers are different polymers and wherein said polar monomer, oligomer, or polymer is selected from 2-hydroxyethyl methacrylate, polyethylene glycol methacrylate or derivatives thereof.
