The grafting of metallocene ethyle-octene copolymer to higher polarity with acrylic acid. Metallocene polyolefins (MePO) were grafted in melt due to increasing their surface free energy and adhesive properties. MePO modification with ozone was used to initiate the creation of peroxides on the surface of the polymer with subsequently grafting of acrylic acid in polymer melt. The efficiency of grafting in melt is high, ranging between 0.77 and 0.97.

Poprawa polarności poprzez szczepienie kopolimeru metalocenowego etylenu i oktenu kwasem akrylowym. Poliolefiny metalocenowe (MePO) szczepiono w stanie stopionym w celu zwiększenia ich swobodnej energii powierzchniowej i właściwości adhezyjnych. Zastosowano modyfikację MePO ozonem do zainicjowania tworzenia nadtlenków na powierzchni polimeru, a następnie stopiony polimer szczepiono kwasem akrylowym. Wydajność szczepienia polimeru w stanie stopionym była wysoka i wahała się między 0,77 a 0,97.

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.
