Embodiment 1
[0050] Embodiment 1 Maleic anhydride-styrene alternating copolymer grafted ethylene-propylene rubber
[0051] 5 g of 4-diphenylgermanium styrene monomer was weighed and dissolved in 250 g of toluene solution, and then the solution was transferred to a 500 ml reactor and stirred evenly, while the temperature of the reactor was raised to 120° C. 20 g of ethylene and 10 g of propylene were introduced into the reactor, and then 600 μmol of MAO and 2 μmol of Ti-based catalyst were added into the reactor to initiate a polymerization reaction for 5 minutes. Take 2 g of the reaction solution and add it into ethanol to obtain 4-diphenylgermanylstyrene functionalized ethylene-propylene rubber. Add 5g of styrene and 5g of maleic anhydride to the remaining reaction solution, raise the temperature of the polymerization reaction to 180°C, and continue the reaction for 4 hours. After the reaction, add 300g of ethanol to the above reaction solution to terminate the reaction and obtain solid p...
Embodiment 2
[0054] Embodiment 2 maleic anhydride-styrene alternating copolymer grafted linear low density polyethylene
[0055] Add 5g of 4-diphenylgermanylstyrene monomer and 5g of 1-butene into 250g of toluene solution, then transfer the solution to a 500ml reactor and stir evenly, while raising the temperature of the reactor to 120°C. 30 g of ethylene was introduced into the reactor, and then 600 μmol of MAO and 2 μmol of Ti-based catalyst were added into the reactor to initiate a polymerization reaction for 5 minutes. Take 2 g of the reaction solution and add it into ethanol to obtain 4-diphenylgermanylstyrene functionalized linear low density polyethylene. Add 5g of styrene and 5g of maleic anhydride to the remaining reaction liquid, raise the temperature of the polymerization reaction to 180°C at the same time, continue the reaction for 4h, add 300g of ethanol to the above reaction solution after the reaction to terminate the reaction to obtain a solid precipitate, dry the solid pre...
Embodiment 3
[0058] Example 3 Maleic anhydride-styrene alternating copolymer grafted polyolefin elastomer
[0059] 5 g of 4-diphenylgermanium styrene monomer was dissolved in 300 ml of toluene solution, and then the above solution was transferred to a 500 ml reaction kettle and stirred evenly. 20 g of 1-octene was added to the reactor via a syringe while raising the temperature of the reactor to 120°C. Feed 30g ethylene into the reactor, then add 600umol of MAO and 2umol of Ti-based catalyst into the reactor to initiate polymerization, and react for 5min. 2 g of the reaction solution was added into ethanol to obtain a 4-diphenylgermanylstyrene functionalized polyolefin elastomer. Then add 5g of styrene and 5g of maleic anhydride to the remaining reaction solution, and simultaneously increase the temperature of the polymerization reaction to 180°C, continue the reaction for 4h, add 300g of ethanol to the above reaction solution after the reaction to terminate the reaction and obtain a soli...
