FIELD: modification of polypropylene by grafting.
SUBSTANCE: invention proposes a polypropylene resin with a grafted polar monomer, a method for its preparation and its use. The grafted polypropylene resin of the present invention is obtained by grafting a polar monomer capable of absorbing microwaves to raise its temperature in a microwave field to more than 200°C, and solid polypropylene resin using microwave irradiation without adding an initiator. In accordance with the present invention, a polar grafted polypropylene resin is obtained, containing no initiator residues and not having a significant reduction in molecular weight compared to the resin prior to grafting.
EFFECT: providing an odour-less polypropylene resin with a grafted polar monomer, which does not contain residual unreacted monomers or auxiliary grafting monomers, while the production method of the present invention is simple, easy to operate, simple in production equipment, cheap and easy for industrial use.
