Embodiment 1

[0021] Add 11.68mL KH550 (50mmol), 6.7g 4-hydroxyphenyl formaldehyde (55mmol), 11.9g DOPO (55mmol) and 300mL chloroform into a 1000mL round bottom flask connected with a condenser, and stir the reaction at 50°C for 12h. After the reaction was completed, the reaction solution was concentrated to about 50 mL by rotary evaporation, and then slowly dropped into iced methanol for precipitation. It was filtered under reduced pressure, washed three times with methanol, and freeze-dried to obtain a white solid.

[0022] Add 27.1g (0.05mol) of previously synthesized phenolic intermediate compound, 10.1g (0.10mol) of triethylamine and 100mL of dichloromethane to a 250mL single-necked round-bottomed flask in sequence, place it at 5°C, and slowly 10.5 g (0.10 mol) of methacryloyl chloride was added dropwise, and stirring was continued for 8 hours after the dropwise addition was completed. After the reaction was completed, triethylamine hydrochloride was removed by filtration, and washed ...

Abstract

Disclosed are a method for synthesizing a phosphorus-containing silicon-containing organic or inorganic internal-hybridized activated monomer, and a use thereof. The method comprises: by using a Kabachnik-Fields reaction, preparing a phosphorus-containing silicon-containing phenol intermediate from 3-aminopropyl triethoxysilane, 4-hydroxybenzaldehyde and DOPO, which serve as raw materials, then subjecting the phenol intermediate and methacryloyl chloride to a reaction in the presence of a solvent and an acid binding agent, and carrying out purification, thereby preparing an active-double-bond-containing phosphorus-silicon organic or inorganic internal-hybridized activated monomer. The elemental composition of the synthesized organic or inorganic internal-hybridized activated monomer can be accurately controlled, and same can be applied to the preparation of functional organic or inorganic hybridized polymers and flame-retardant, anticorrosive, heat-resistant and weather-resistant modified materials.

Description

technical field [0001] The invention relates to a synthesis method and application of a phosphorus-containing and silicon-containing organic-inorganic internal hybrid active monomer. Background technique [0002] Organic / inorganic hybrid material is a new type of composite material, which has the advantages of light weight, easy processing, molecular level design of organic materials and high rigidity, good oxidation resistance and heat resistance of inorganic materials. , has developed rapidly in recent years. The structural feature of the organic / inorganic internal hybrid monomer is that the molecule has a heteroatom-containing group and a polymerizable double bond at the same time, and chemically bonds elements such as silicon, phosphorus, and fluorine with carbon, hydrogen, oxygen, and nitrogen. The combination of such elements realizes the synergistic effect of organic elements and inorganic elements at the molecular level; at the same time, the double bond is reactive...
