A COMPARISON OF RADIATION-INDUCED GRAFT COPOLYMERIZATION UTILIZING ELECTRON ACCELERATORS AND ISOTOPE SOURCES AS RADIATION INITIATORS. Progress Report for January 1961

Technical Report ·
OSTI ID:4086709
A project was initiated to investigate the basic mechanism of the grafting process via the determination of the relative reactivities of various monomers in graft copolymerization. The copolymer composition of methacrylic acid-styrene grafts on polypropylene film, Co/sup 60/ and electron accelerator initiated, were analyzed by an infrared technique. The Co/sup 60/ initiation resulted in a more constant molar ratio of methacrylic acid to styrene than did the accelerator initiation. The machine grafting of methacrylic acid-styrene to polypropylene film was found to have a less than half-order dependency on the dose rate when grafting was confined to total doses that did not generate heat during the irradiation.
