Modification Research on Polypropylene with Acrylic-Silicon Oil Lanthanum

It is hard that inducting rare earth into common resin by bond combination. General plastic polypropylene (PP) containing rare earth was prepared by the bond combination of PP and acrylic-silicon oil lanthanum, which was obtained by reaction of acrylic acid ethylene silicon oil. The principle and method of the graft copolymerization of PP and acrylicsilicon oil lanthanum were discussed. The graft copolymer was characterized by scanning electron microscope (SEM). The mechanical property of graft copolymer was measured by electronic tensile testing machine and impact testing machine. The experimental results showed that crosslinking reaction between PP and acrylic-silicon oil lanthanum happened, acrylic-silicon oil lanthanum did not harm PPʹs performances. PPʹs tensile strength almost kept the same and impact strength obviously increased.
