Solid Phase Graft Copolymerization of PE-G-MA
The solid phase graft copolymerization method was used to graft meleic anhydride onto commercial polyethylenes. This process is environmentally friendly since it requires minimal recovery or no use of solvent and the process conditions are mild. NMR analysis confirms the successful grafting of maleic anhydride onto the backbones of both linear low-density polyethylene (LLDPE) and ultra high molecular weight polyethylene (WHMWPE). Graft levels for all the polymers were quantified by FTIR absorbance as well as wet-chemical titration. Significant processing parameters were identified based on statistical design of experiments.
