Redox-initiated ab Initio RAFT Emulsion Polymerization of Styrene by Amphiphilic Macro RAFT Agent |
| 초록 |
RAFT emulsion polymerization is a novel method to synthesize polymeric particles. In this method, thermal initiator is usually used as a radical source. But there is hardly enough study about redox initiator in literature. In this study, we synthesized polystyrene by RAFT emulsion polymerization via redox initiator using a hydrophilic macro CTA poly(n-hydroxyethyl acrylamide (HEAA)) and a amphiphilic macro CTA poly((n-hydroxyethyl acrylamide (HEAA))-block-(styrene)) (PHEAA-b-PS). As redox initiator generates radicals rapidly, terminations are highly possible before micelle is formed. Thus, we examined the effect of amphiphilicity in macro CTAs as they form the micelle. After the reaction, unreacted macro CTA remained as residue. The residual macro CTA and grown chains were separated and quantified to know the amount of RAFT agent participated in the reaction. The separated chain was characterized by 1H NMR and size exclusion chromatography(SEC). |
