다국어 초록 (Multilingual Abstract)

In previous research, we reported the synthesis process of SPCs resins containing poly(ethylene glycol)(PEG) groups based on Zinc methacylate. In that process, we used Benzoyl Peroxide(BPO) as an initiator and dissolved in liquid monomers. Even though this method had not risks at the lab scale, there is a possibility of an explosion in mass production processes due to the high reactivity and the change of solubility of BPO in monomer mixtures. Thus we investigated the optimum conditions for an initiator for mass productions, while maintaining the original properties of a basic SPC resin. The first method was the separation of a initiator from the monomer. The second method was the exchange of BPO to other liquid initiators. And we synthesised the SPC resins employing the mixture of BPO and other liquid initiators. We conducted basic physical properties of resins: non-volatile contents (NV), viscosity, hardness, reaction time to NaOH solutions.
