Mineral filler: magnesium oxide (MgO) has been modified by grafting process initiated by high energy (9 MeV) electron beam treatment. Many vinyl monomers as methyl methacrylate (MMA), maleic anhydride (MA) were used as modifying compounds. The yield of momomers grafting on MgO have been determined as dose depended with optimum at dose 20 - 30 kGy. Fillers have been milled after grafting and its properties have been investigated by FTIR, DSC and TG methods. Modified fillers have been used in compositions with polyethylene (LDPE). SEM was used for investigation of the structure of obtained samples. Mechanical and some thermal properties of selected samples have been measured and discussed. The work present preliminary data of influence of dose level and monomer type on properties of the samples. Generally, the filled polyethylene has been characterized by better dispersibility and betters some mechanical properties. The works will be continued and its results will be useful in similar work on filling of polymers with nanoparticles.
