Abstract
The interpenetrating polymer networks (IPNs) formed diglycidyl ether of bisphenol-A (DGEBA) and poly (ethylene glycol) diacrylate (PEGDA) were prepared by simultaneous polymerization techniques. Methylhexahydrophtalic anhydride was used as curing agent for DGEBA. AIBN, BPO or DTBPO was used as radical initiators for PEGDA. The resultant products were analyzed by DMA measurements and AFM observation. As the results, the product induced by AIBN initiators system have phase-separated IPN structure. In the case of BPO initiation systems, sequential IPN was obtained. From, AFM observations, the phase image clearly shows the phase-separated structure between PEGDA and DGEBA domains.
