Abstract: This paper reports the synthesis of polyglycidyl urethane of polyaryl methene (PGUPA) from polyaryl methene polyisocyanate (PAPI) and 2,3- epoxy- 1- propanol. It is a glycidyl urethane type of epoxy resin (UE-712), and the chemical structure of UE-712 resin was appraised by elemental analysis and infrared spectra. Experiments of DWA, DSC, IR, mechanical and heat resistant properties for UE-712 resin system showed that polyglycidyl urethane resin (UE-712) has a higher activity of curing than polyglycidyl ether resin (F-51) and has clear self-curing characteristic. Mechanical and heat resistant properties of curing system of UE-712 resin are better than those of F-51 resin too.
