제목 Effect of radiation on melt strength of polypropylene with polyfunctional monomer
초록 In the present study, the effects of electron beam irradiation and addition of polyfunctional monomer on the melt strength of polypropylene(PP) were investigated. To improve melt strength, the PP films prepared by blending with 1,4 butanediol dimethacrylate and diethyleneglycol dimethacrylate as a polyfunctional monomer(PFM) were irradiated with an electron beam at an acceleration energy of 1 MeV. The concentration of the polyfunctional monomer was below 3 parts per hundred resin(phr). The EB irradiation was conducted from 1kGy to 100kGy in nitrogen. Following irradiation, the PP specimens with polyfunctional monomer were thermally treated at 160oC to eliminate all the remaining free radicals. The melt strength of the irradiated PP was measured by tensile tester for polymer melts(Rheotens, Göettfert GmbH, Germany) at 210oC. Dynamic mechanical analysis and tensile property of these irradiated specimens have been investigated as well.
