Abstract
A copolymer of DCPD-containing benzoxazine (DCPDBz) and cyanate ester resin forms a low-dielectric thermosetting polymeric material for making electronic components. A method of manufacturing the copolymer is also introduced. The method includes allowing DCPD-phenol oligomer, aniline, and paraformaldehyde to react at 110° C. for 6-12 hours before being extracted and baked to obtain DCPDBz; and mixing cyanate ester and the DCPDBz at 150° C.; heating the mixture up to 220° C.
