摘要：
The ESR method was used for investigating free radicals formed during thermal decomposition of dibenzoyl peroxide in the poly(methyl methacrylate) (PMMA)-maleic anhydride (MAN) system at 400 MPa. No primary product from the addition of a polymer radical to maleic anhydride was observed, but instead a polyene radical was formed within the polymer matrix. Possibilities of the formation of polyene radicals as well as the effect of temperature and reaction time on the concentration of free radicals are discussed.
