New epoxide and cyanate ester resins with an aromatic ester backbone namely 1,3-[di-(4-glycidyloxy diphenyl-2,2
′-propane)]-isophthalate (DGDPI) and 1,4-[di-(4-cyanato diphenyl-2,2
′-propane)]-terephthalate (DCDPT) were synthesized and the intermediates were characterized by IR,
1
H-/
13C-NMR spectroscopic methods. The cured products from DGDPI and DHDPI exhibited higher
T
g compared with standard epoxy system. The increase in the
T
g may be due to the cyanate ester and rigid aromatic backbones present in the curing system.
