Abstract
A polyphenylene ether bismaleimide resin, a method for manufacturing the same, and a resin composition are provided. The polyphenylene ether bismaleimide (PPE-BMI) resin is obtained by a condensation reaction with a maleic anhydride and a primary amine compound as reactants. The primary amine compound is a polyphenylene ether diamine.

A method for manufacturing a polyphenylene ether bismaleimide resin, comprising:
- mixing a maleic anhydride, a primary amine compound, and a solvent, and performing a condensation reaction at a temperature of 100 to 130° C. to obtain the polyphenylene ether bismaleimide resin having a weight-average molecular weight of 2800 to 4500 g/mol, wherein the structural formula of the polyphenylene ether bismaleimide resin is:
- wherein each of m and n is an integer greater than or equal to 9 and less than 16,
- wherein in the reactant, a molar number of the maleic anhydride is 1.2 to 2.5 times a molar number of total amine groups of the primary amine compound.
