Efficient method of metallocene polyolefin grafting in solution was used to initiate the creation of peroxides and hydroperoxides molecules accumulated on polyolefin after activation controlled by thermal oxidation. Efficacy of grafting of RXP in toluene was relatively low and reached the value 0.24 - 0.49.

The activated RXP suspended in an aqueous acrylic acid (AA) solution does contain peroxide groups in sufficient concentration. The temperature of 60°C is too low to generate free radicals to initiate grafting. FTIR absorbance for acid carbonyl compounds at 1715 cm-1 and at 1464 cm-1 show the proliferation of PAA graft quantity depending on the amount of AA in the feedstock.
