Problems solved by technology

However, the only monomers that can achieve anionic polymerization are styrene and a small amount of diene monomers, so this method cannot be extended to the polarization of ethylene and propylene-based polyolefin materials.

Embodiment 1

[0050] Example 1 Maleic anhydride-styrene alternating copolymer grafted ethylene propylene rubber

[0051] 5g of 4-diphenylgermanium styrene monomer was weighed and dissolved in 250g of toluene solution, and then the solution was transferred to a 500ml reaction kettle and stirred evenly, while the temperature of the reaction kettle was raised to 120°C. Feed 20g of ethylene and 10g of propylene into the reaction kettle, then add 600umol of MAO and 2umol of Ti-based catalyst into the reaction kettle to initiate a polymerization reaction, and react for 5min. 2 g of the reaction solution was added to ethanol to obtain 4-diphenylgermanyl styrene functionalized ethylene-propylene rubber. Add 5g of styrene and 5g of maleic anhydride to the remaining reaction solution, at the same time increase the polymerization temperature to 180°C, continue the reaction for 4h, after the reaction is completed, add 300g of ethanol to the above reaction solution to terminate the reaction to obtain so...

[0054] Example 2 Maleic anhydride-styrene alternating copolymer grafted linear low density polyethylene

[0055] 5g of 4-diphenylgermanium-based styrene monomer and 5g of 1-butene were added to 250g of toluene solution, then the solution was transferred to a 500ml reactor and stirred evenly, while the temperature of the reactor was raised to 120°C. Feed 30g of ethylene into the reaction kettle, then add 600umol of MAO and 2umol of Ti-based catalysts into the reaction kettle to initiate a polymerization reaction, and react for 5min. 2 g of the reaction solution was taken and added to ethanol to obtain 4-diphenylgermanyl styrene functionalized linear low density polyethylene. Add 5g of styrene and 5g of maleic anhydride to the remaining reaction solution, at the same time increase the polymerization temperature to 180°C, continue the reaction for 4h, after the reaction is completed, add 300g of ethanol to the above reaction solution to terminate the reaction to obtain a solid pr...

[0058] Example 3 Maleic anhydride-styrene alternating copolymer grafted polyolefin elastomer

[0059] Dissolve 5g of 4-diphenylgermanium styrene monomer in 300ml of toluene solution, then transfer the above solution to a 500ml reaction kettle and stir evenly. 20 g of 1-octene was added to the autoclave via a syringe while the autoclave temperature was raised to 120°C. Feed 30g of ethylene into the reaction kettle, then add 600umol of MAO and 2umol of Ti-based catalysts into the reaction kettle to initiate a polymerization reaction, and react for 5min. 2 g of the reaction solution was added into ethanol to obtain a 4-diphenylgermanyl styrene functionalized polyolefin elastomer. Then 5g of styrene and 5g of maleic anhydride were added to the remaining reaction solution, and the polymerization temperature was raised to 180°C, and the reaction was continued for 4h. After the reaction was completed, 300g of ethanol was added to the above reaction solution to terminate the reaction...

Abstract

The present invention relates to a germanium-containing styrene derivative monomer and a preparation method thereof, a functionalized polyolefin containing germanium-styrene derivatives and the use thereof. The functionalized polyolefin containing germanium styrene derivatives is the polymerization product of ethylene, α-olefin and germanium-containing styrene derivative monomers, C-Ge bonds are introduced into the side chains of the polymer, and the obtained polyolefin is further used as the largest polymer. Molecular initiators initiate free radical polymerization of functionalized monomers to prepare functionalized side-chain grafted polyolefins. It can effectively control the molecular weight and distribution of olefin copolymers, and at the same time, different functionalized polymer side chains can be introduced into the polyolefin side chains, such as polymethyl methacrylate side chains, polyglycidyl methacrylate side chains, styrene / Maleic anhydride copolymer side chains, etc. The number of functionalized side chains can be regulated by changing the content of 4-diphenylgermanystyrene.

Description

technical field [0001] The invention belongs to the field of olefin polymerization, and relates to a functionalized polyolefin containing germanium styrene derivatives and a method for preparing a polar monomer functionalized grafted polyolefin. Background technique [0002] Polyolefin products have the characteristics of low price, good mechanical properties and thermal stability, wide adjustable range of crystallinity, easy processing, etc., and are widely used in industry, agriculture, medical, military and other fields. However, polyolefin materials are non-polar structures, so their printability, hydrophilicity, colorability, and poor compatibility with other polar materials and inorganic fillers greatly limit the application of polyolefin materials. Synthesis of polyolefins grafted with functionalized side chains is an important approach to improve the polarity and functionality of polyolefin materials. [0003] Since functional monomers are generally polar monomers, ...
