Synthesis and Investigation of Properties of Epoxy-Novolac Copolymers Based on Polycyclic Bisphenols of Norbornane Type
The purpose of this study was the synthesis of copolymers based on the novolac oligomer and diglycidal ether of polycyclic bisphenols of the norbornane type and the study of the curing process of the obtained copolymers. Copolymers were synthesized based on polycyclic bisphenols: 4,4'-(2-norbornilidene) diphenyl; 4,4'-(hexahydro-4,7-methylenindane)-di-o-cresol; 4,4′-(hexahydro-4,7-methylenindane-5-ylidene) diphenol; 4,4′-(decahydro-1,4,5,8 - dimethylennaft-2-ylidene)diphenol; and 2,2-bis-(4-oxyphenyl)propane. The synthesis was carried out in two stages.
