Amphiphilic Heteroarm Core Cross-Linked Star Polymer as Janus Nanosurfactants |
| 초록 |
Heteroarm core cross-linked star (CCS) polymers possesses two different kinds of polymer arms covalently attached to a cross-linked core. If hydrophilic and hydrophobic polymer arms in the CCS architecture are intramolecularly segregated, the amphiphilic heteroarm CCS polymers are expected to behave as effective emulsifiers as Janus polymer nanooojbects with two distinct faces. Here we discuss synthesis of such an amphiphilic heteroarm CCS polymer and their phase behavior. The CCS polymer was prepared by RAFT alternating copolymerization of styrene and bismaleimide in the presence of a hydrophilic macro-chain transfer agent, which is followed by chain extension with a hydrophobic monomer. Investigation of their phase behavior in solution and interfacial properties suggests that intramolecular segregation in the CCS architecture. |
