Synthesis of amphiphilic poly(cyclooctene)-graft-poly(ethylene glycol) copolymers via ROMP and its surface properties
关键字：amphiphilic, poly(cyclooctene)-graft-poly(ethylene glycol), ROMP, surface properties
Macromonomer cyclooctene-poly(ethylene glycol) (cyclooctene-PEG) was first synthesized before being copolymerized with cyclooctene by ring opening metathesis polymerization (ROMP) to obtain an amphiphilic graft copolymer (poly(cyclooctene)-g-PEG) with polycyclooctene as the hydrophobic trunk chain and PEG as hydrophilic side chains. The structure of poly(cyclooctene)-g-PEG copolymer...

Surface modification of poly(styrene-b-(ethylene-co-butylene)-b-styrene) elastomer via UV-induced graft polymerization of N-vinyl pyrrolidone
关键字：Styrenic block copolymers, UV-induced graft polymerization, N-vinyl pyrrolidone (NVP), Hemocompatibility
Poly(N-vinyl pyrrolidone) (PNVP) was covalently grafted onto the surface of biomedical poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) elastomer via a technique of UV-induced graft polymerization combined with plasma pre-treatment. The surface graft polymerization of N-vinyl pyrrolidone (NVP) was confirmed by ATR-FTIR and XPS. Effect of the parameters of graft polymerization, i...

Preparation of poly(ethylene glycol)-b-polyacrylonitrile block copolymer functioned multi-walled carbon nanotubes by “graft onto” and “graft from”
关键字：MWNTs, poly(ethylene glycol), polyacrylonitrile, coupling reaction, redox free polymerization
Multi-walled carbon nanotubes (MWNTs) were oxidized with concentrated HNO3 and H2SO4 to introduce carboxylic groups. Grafting of poly (ethylene glycol) (PEG) onto carbon nanotubes (MWNTs-g-PEG) was achieved by the direct condensation reaction&nb...
