[0069] Example 1-12: Preparation and performance testing of multifunctional polar polyolefin materials

[0070] (1) Preparation of Embodiment 1-10:

[0071] In a glove box, under a nitrogen atmosphere, comonomers (i.e., α-olefin comonomer (Hex) and eugenol mono The respective molar concentrations of the monomers (Eug, Eug-Si or Eug-OH) are indicated in brackets after the corresponding comonomers. For example, when the total reactant volume is 20mL, for the random obtained in Example 4 Copolymer E / Eug-Si(0.1) / Hex(4), the molar number of Eug-Si comonomer is 2mmol, and the molar number of Hex comonomer is 80mmol), and add and dissolve in 1mL 20 μmol of catalyst PO-Pd in ​​dichloromethane. Then, connect the ethylene gas source pipeline to feed ethylene (monomer E) gas into the reactor, and after adjusting the ethylene pressure to 8atm or 3atm, under magnetic stirring, the reactor was heated to 80°C by heating in a water bath and heated in a water bath. React under magnetic stir...

Abstract

The invention relates to a novel multifunctional polar polyolefin material as well as a metal complex material, a preparation method and an application thereof. The multifunctional polar polyolefin material is a random copolymer formed by copolymerizing an ethylene monomer represented by a formula CH2 = CH2, an alpha-olefin comonomer represented by a formula CH2 = CH-(CH2) m-CH3 and an eugenol comonomer represented by the formula, wherein m, X and Y are as defined herein, the multifunctional polar polyolefin material can be simply and effectively prepared under mild conditions, and can be usedas a compatible agent and an adhesive, and a multifunctional polar polyolefin metal complex material with significantly improved mechanical properties and a self-repairing function can be obtained after transition metal modification.

Description

technical field [0001] The invention belongs to the field of functional polymer polyolefin materials, and in particular relates to multifunctional polar polyolefin materials and metal complex materials, preparation methods and applications thereof. Background technique [0002] Since the last century, polymer materials have penetrated into every aspect of human life, partly due to their excellent thermal, mechanical, rheological and even optical properties, which can be adjusted by adjusting the composition and structure of the polymer or changing the polarity The types of functional groups are fine-tuned. Polyolefins, derived from readily available low-cost olefin feedstocks such as ethylene, propylene and other α-olefins, have become the most widely produced polymers in the world. Because of its cheap, light and durable characteristics, it has been used as a substitute for traditional materials such as wood, metal and glass, and is widely used in pipes, films, packaging, ...
