Embodiment Construction

[0080] For better illustrating the present invention, facilitate understanding technical scheme of the present invention, typical but non-limiting embodiment of the present invention is as follows:

[0081] (1) Redistribution of PPO

[0082] Stir and heat 400g of toluene in a three-necked flask equipped with a stirrer, condensing reflux tube, and thermometer to 102°C, then add 100g of PPO resin with a number average molecular weight of 20,000, and add 6g of diallyl bis Phenol A (DABPA), stirred for 30 minutes, then added 7.5 g of tert-butyl peroxyisobutyrate dissolved in toluene, and kept the temperature at 102 ° C, and reacted for 180 minutes.

[0083] (2) Modified PPO reacts with BMI

[0084] In (1), the temperature of the reaction product was raised to 140 degrees Celsius, and 13.9 g of diphenylmethane-type BMI was added. After the BMI was dissolved, the reaction was stopped after 5 hours of reaction, poured out, and cooled.

[0085] Repeating the above operations, changi...

Abstract

The invention relates to a crosslinkable polyphenyl ether resin. The crosslinkable polyphenyl ether resin has a structure in a chemical formula (F). A preparation method of the polyphenyl ether resin is also disclosed by the invention. A high-frequency circuit substrate prepared from the crosslinkable polyphenyl ether resin disclosed by the invention is high in glass-transition temperature, good in heat resistance, low in water absorption rate, high in interlayer binding force, and excellent in dielectric property.

Description

technical field [0001] The present invention relates to a kind of cross-linkable polyphenylene ether resin, preparation method and application thereof, especially to a kind of preparation method of cross-linkable polyphenylene ether resin, which is to redistribute macromolecular polyphenylene ether resin Be modified to convert it into a thermosetting resin. Background technique [0002] Polyphenylene ether (PPO) resin has excellent dielectric properties (second only to PTFE) and high T g , so some people try to introduce PPO resin into FR-4 to improve the electrical properties of FR-4 so that it can be used in high-frequency substrate materials. However, polyphenylene ether resin is a thermoplastic resin and will dissolve in halogenated hydrocarbons and aromatic solvents. At the same time, because of the large molecular weight and high symmetry of PPO resin, it has a large structural difference from epoxy resin, making it compatible with epoxy resin. Poor compatibility mak...
