Chad A Strait, Gerald M Lancaster, Ricky L Tabor: Method of grafting maleic anhydride to polymers. The Dow Chemical Company, Walter J Lee, August 9, 1988: US04762890 (79 worldwide citation)

Maleic anhydride can be satisfactorily grafted to polymers at low pressures by feeding the polymer through a co-rotating, twin-screw extruder and injecting the maleic anhydride and a free radical initiator into the extruder. The maleic anhydride and initiator can be pre-mixed in a solvent solution. ...
