Example Embodiment
[0098] Example 1
[0099] Add 3000g of water and 30g of sodium hydroxide into a four-necked flask, add 95g of diallyl bisphenol A after the temperature drops to room temperature, place this solution in an ice salt bath, wait until the temperature drops below 20℃, and start adding bromine dropwise 150g of ethane, control the temperature to be lower than 20°C, react at low temperature for 30min after the dropping, raise the temperature to 50°C for 2h, stop the reaction, cool down, separate the phases, and wash with water to obtain ethyl etherified diallyl bisphenol A .
[0100] Take 1 mol of ethyl etherified diallyl bisphenol A and 1 mol of diphenylmethane bismaleimide synthesized above into the flask, heat to 145°C, stir for 30 minutes, pour out and cool to obtain ethyl ether Diallyl bisphenol A and diphenylmethane bismaleimide prepolymer.
[0101] figure 1 It is the infrared spectrum of the prepolymer of ethyl etherified diallyl bisphenol A and diphenylmethane bismaleimide synthes...

[0104] Example 2
[0105] Take 1 mol of ethyl etherified diallyl bisphenol A synthesized in Example 1 and 0.5 mol of diphenyl sulfone bismaleimide into a flask, heat to 140°C, stir for 90 minutes, pour out and cool to obtain ethyl A prepolymer of diallyl bisphenol A and diphenyl sulfone bismaleimide.
[0106] Take 30 parts of prepolymer of ethyl etherified diallyl bisphenol A and diphenyl sulfone bismaleimide synthesized above, and 30 parts of polyphenylene ether resin (SA9000) with unsaturated double bond at molecular end , 16 parts of bisphenol A cyanate ester, 12 parts of decabromodiphenylethane, 25 parts of fused silica powder, 2 parts of 2,5-bis(2-ethylhexanoylperoxy)-2,5-dimethyl Base 3-hexyne, use toluene to dissolve the above compound and prepare a glue of suitable viscosity. Use 2116 electronic grade glass cloth to soak the glue, and remove the solvent in a 135℃ oven to obtain a B-stage prepreg sample with a resin content of 54%.
[0107] Eight pieces of the above-prepare...

[0108] Example 3
[0109] Take 1 mol of ethyl etherified diallyl bisphenol A synthesized in Example 1 and 0.5 mol of diphenyl sulfone bismaleimide into a flask, heat to 140°C, stir for 90 minutes, pour out and cool to obtain ethyl A prepolymer of diallyl bisphenol A and diphenyl sulfone bismaleimide.
[0110] Take 30 parts of the prepolymer of ethyl etherified diallyl bisphenol A and diphenyl sulfone bismaleimide synthesized above, polyphenylene ether resin (SA9000) 30 with unsaturated double bond at the molecular end, 12 parts of decabromodiphenylethane, 25 parts of fused silica powder, 2 parts of 2,5-bis(2-ethylhexanoylperoxy)-2,5-dimethyl-3-hexyne, use toluene to The compound is dissolved and prepared into a glue of suitable viscosity. Use 2116 electronic grade glass cloth to soak the glue, and remove the solvent in a 135℃ oven to obtain a B-stage prepreg sample with a resin content of 54%.
