Abstract

The intermediate monomer dicyclopentene-furanmethylamine (DCPD-F) was firstly synthesized by Diels-Alder reaction using dicyclopentadiene and furanmethylamine as raw materials.And then the synthesized(DCPD-F) and bisphenol A and formaldehyde were used as raw materials through Mannich reaction to synthesize a benzoxazine(DCPD-F-BOZ) with bridged rings structure,which was cured at high temperature to form a thermosetting resin.The chemical structure of DCPD-F and DCPD-F-BOZ was characterized by FT-IR and NMR.The curing behavior of DCPD-F-BOZ was characterized by DSC,which two peaks at about 223℃ and 258℃ appeared during its curing,respectively.The themal stability of poly(DCPD-F-BOZ) was analyzed by TGA,with the dielectric constant being tested.The results showed that poly(DCPD-F-BOZ) had excellent thermal stability under the condition of nitrogen,which began to decompose at 360℃ with 5% mass loss temperature of 382℃.The char yield rate at 800℃ was 53% and the dielectric constant at room temperature was 2.96(1GHz).
