In this paper,dicyclopentadiene (DCPD) and phenol were used as raw materials,and BF3·Et2O was used as catalyst for alkylation reaction to produce dicyclopentadiene phenol resin (DPR).By changing the reaction time,reaction temperature,raw material ratio,catalyst amount,orthogonal experiment was used to explore the optimal process conditions of alkylation reaction under different conditions,ensuring that the synthesized resin could meet the requirements for electronic application.When the reaction conditions were 2h,110℃,the raw material ratio was 8∶1,and the catalyst dosage was 0.5%,the component content of polymerization degree n=0 could reach 91.02%,and the product met the requirements of DPR for electronic application.
