Abstract
A benzoxazine resin and a method for manufacturing the same, and a resin composition are provided. The benzoxazine resin is obtained from a condensation polymerization reaction of a phenolic compound, formaldehyde, and a primary amine compound that are used as a reactant. The phenolic compound includes a dicyclopentadiene phenol resin and bisphenol A. The primary amine compound includes 2,6-dimethylaniline and m-xylylenediamine. The resin composition includes the benzoxazine resin, an epoxy resin, and a bismaleimide resin. Based on a total weight of the benzoxazine resin, the epoxy resin, and the bismaleimide resin being 100 phr, an amount of the benzoxazine resin ranges from 30 phr to 50 phr.
