Effect of different content of C 60 on the melt radical reaction between trimethylol propane triacrylate (TMPTA) and polypropylene (PP) was studied by means of Fourier transform infrared, melt torque values, and rheological results. C 60 could transfer most of the reactive PP macroradicals to more stable macroradicals at first due to its higher reaction rate with radicals. Therefore, the homopolymerization of TMPTA was restrained to some extent. PP samples containing TMPTA, C 60 , and 2,5‐dimethyl‐2,5( tert ‐butylperoxy) hexane peroxide (DHBP) showed a more obvious influence on increasing the entanglements between PP chains comparing with PP samples containing C 60 and DHBP, owing to the synergetic effect between TMPTA and C 60 on branching with PP macroradicals. © 2012 Wiley Periodicals, Inc.
