Example Embodiment
[0025] Example one
[0026] A preparation method of bisphenol A type cyanate ester resin prepolymer uses bisphenol A type cyanate ester monomer as the main material and polyphenylene ether as the auxiliary material. The preparation process is as follows:
[0027] Take 100g of bisphenol A cyanate ester monomer and heat and melt it at 140°C; then add 5g of polyphenylene ether with a number average molecular weight of 1500g / mol, and continue the reaction for 10 hours while keeping stirring. When the refractive index of the system reaches 1.584 , The temperature is lowered to end the reaction; when the cooling temperature reaches about 75°C, 45g of methyl ethyl ketone is added to the polymer, stirred evenly and cooled to room temperature to obtain a bisphenol A cyanate ester resin prepolymer with a solid content of 70%.
Example Embodiment
[0028] Example two
[0029] A preparation method of bisphenol A type cyanate ester resin prepolymer uses bisphenol A type cyanate ester monomer as the main material and polyphenylene ether as the auxiliary material. The preparation process is as follows:
[0030] Take 100g of bisphenol A cyanate ester monomer and heat and melt it at 150°C; add 1g of polyphenylene ether with a number average molecular weight of 1500g / mol, and continue to heat and react for 8 hours while stirring. When the refractive index of the system reaches 1.585, The temperature is lowered to complete the reaction; when the cooling temperature reaches about 75° C., 43.3 g of methyl ethyl ketone is added to the polymer, stirred uniformly, and cooled to room temperature to obtain a bisphenol A cyanate ester resin prepolymer with a solid content of 70%.
Example Embodiment
[0031] Example three
[0032] A preparation method of bisphenol A type cyanate ester resin prepolymer uses bisphenol A type cyanate ester monomer as the main material and polyphenylene ether as the auxiliary material. The preparation process is as follows:
[0033] Take 100g of bisphenol A cyanate ester monomer and heat and melt it at 160℃; add 0.5g of polyphenylene ether with a number average molecular weight of 1000g / mol, and continue to heat and react for 6 hours while stirring. When the refractive index of the system reaches 1.587 , The temperature is lowered to end the reaction; when the cooling temperature reaches about 75° C., 43.1 g of butanone is added to the polymer, stirred uniformly and cooled to room temperature to obtain a bisphenol A cyanate ester resin prepolymer with a solid content of 70%.
