Embodiment 1
[0150]
[0151] In a four-necked flask equipped with a stirrer, a cooling tube, and a dropping funnel, 100 parts by weight of a propylene-ethylene copolymer (88% by weight of a propylene component, 12% by weight of an ethylene component, a weight-average molecular weight of 60,000, and Tm=65° C.) Heating and dissolving in 400g of toluene, and then while keeping the temperature in the system at 110°C and stirring, added dropwise 4.2 parts by weight of maleic anhydride, 2.6 parts by weight of lauryl methacrylate, The di-tert-butyl group was oxidized and further reacted for 1 hour. After the reaction, it was cooled to room temperature, and then the reactant was put into a large excess of acetone and purified to obtain a weight-average It is 3.2 weight%, and the graft weight of lauryl methacrylate is 2.0 weight% of modified polyolefin resin 1. It should be noted that the graft weight of maleic anhydride is measured by alkaline titration, and the graft weight of lauryl methacryl...

[0161] In a four-necked flask equipped with a stirrer, a cooling tube, and a dropping funnel, 100 parts by weight of a propylene-ethylene copolymer (88% by weight of a propylene component, 12% by weight of an ethylene component, a weight average molecular weight of 100,000, and Tm=65° C.) Heating and dissolving in 400g of toluene, and then while keeping the temperature in the system at 110°C and stirring, 1.0 parts by weight of maleic anhydride, 1.2 parts by weight of octyl methacrylate, 1 part by weight of The di-tert-butyl group was oxidized and further reacted for 1 hour. After the reaction, it was cooled to room temperature, and then the reactant was put into a large excess of acetone and purified to obtain a weight-average molecular weight of 70,000, Tm=65°C, Tg=-27°C, maleic anhydride Modified polyolefin-based resin 2 with 0.8% by weight and 1.0% by weight of octyl methacrylate graft weight.

[0165]
[0166] In a four-necked flask equipped with a stirrer, a cooling tube, and a dropping funnel, 100 parts by weight of a propylene-ethylene copolymer (88% by weight of a propylene component, 12% by weight of an ethylene component, a weight average molecular weight of 100,000, and Tm=65° C.) Heating and dissolving in 400g of toluene, and then while maintaining the temperature in the system at 110°C and stirring, 2.5 parts by weight of maleic anhydride, 1.8 parts by weight of lauryl methacrylate, 1 part by weight of The di-tert-butyl group was oxidized and further reacted for 1 hour. After the reaction, it was cooled to room temperature, and then the reactant was put into a large excess of acetone and purified to obtain a weight-average molecular weight of 70,000, Tm=65°C, Tg=-27°C, maleic anhydride Modified polyolefin-based resin 3 having 2.2% by weight and a lauryl methacrylate graft weight of 1.6% by weight.
