Problems solved by technology

[0005] EP1489079A1 mentioned the method of anhydride capping of polyphenylene ether molecules, using low-molecular-weight bifunctional polyphenylene ether to react with trimellitic anhydride acid chloride, because the acid chloride is easily hydrolyzed, which increases the difficulty of the reaction process and the complexity of equipment and manufacturing costs
[0006] In summary, the existing technology still has great limitations in the modification of polyphenylene ether

Abstract

The invention discloses polyfunctional group polyphenylene ether resin and a preparation method thereof. The method is characterized by comprising the following steps: in a reactor, adding polyphenyl ether, a solvent and diallyl bisphenol A or tetraallyl bisphenol A, and adding a peroxide initiator for reaction for 1-10h at 30-90 DEG C; adding alkali metal hydroxides and a phase transfer catalyst, and dropwise adding 3-allyl chloride for reaction for 6-24h at 30-50 DEG C; distilling a reaction solution, recovering fraction below 50 DEG C, and then adding 40% peracetic acid for reaction for 5-15h at 20-60 DEG C; extracting the reaction solution with deionized water for three times, distilling off most of the solvent from the extraction liquid, then dropwise adding the residual solution in methanol for precipitation and filtration, and finally washing solids with methanol and drying to obtain the polyfunctional group polyphenylene ether resin. The polyphenylene ether resin and other resins can form a composition with multiple uses, and the polyphenylene ether resin can be used for manufacturing films or copper coated substrates of printed circuit boards and other fiber cloth laminated boards.

Description

technical field [0001] The invention belongs to the preparation of organic macromolecular compounds, and relates to a preparation method of polyphenylene ether resin with multifunctional groups (containing epoxy groups, hydroxyl groups and double bonds). The multifunctional polyphenylene ether resin prepared by the invention can form different multi-purpose compositions with other resins, and is used for making films of printed circuit boards or copper-clad substrates and other fiber cloth laminates. Background technique [0002] With the rapid development of the information industry, higher requirements have been put forward for the matrix resin for copper clad laminates, requiring it to have low dielectric constant and dielectric loss, high glass transition temperature, high heat resistance, and low water absorption. Polyphenylene ether resin (PPE) has good comprehensive properties, especially high glass transition temperature and excellent dielectric properties, and is on...
