AbstractAmphiphilic diblock copolymer poly(methyl methacrylate)-b-poly(acrylic acid) (PMMA-b-PAA) was prepared by 1,1-diphenylethene (DPE) method. Firstly, free radical polymerization of methyl methacrylate was carried out with AIBN as initiator in the presence of DPE, giving a DPE-containing PMMA precursor with controlled molecular weight. tert-Butyl acrylate (tBA) was then polymerized in the presence of the PMMA precursor, and PMMA-b-PtBA diblock copolymer with controlled molecular weight was prepared. Finally, amphiphilic diblock copolymer PMMA-b-PAA was obtained by hydrolysis of PMMA-b-PtBA. The formation of PMMA-b-PAA was confirmed by 1H NMR spectrum and gel permeation chromatography. Transmission electron microscopy and dynamic light scattering were used to detect the self-assembly behavior of the amphiphilic diblock polymers in methanol.

Organic/inorganic hybrid materials based upon stimuli-responsive copolymers have attracted an inceasing attention. Compared with the polymeric materials, these hybrid materials can form aggregates in aqueous solution with much more stable shape-persistance due to the inorganic structure, which facilitate the mass delivery and long-term life. A novel hybrid material based on a new reactive block copolymer, poly(ethylene oxide)-block-poly{3-(trimethoxysilyl)propyl methacrylate-co-N-isopropylacrylamide-co-6-[4-(4-methoxyphenylazo)phenoxy]hexyl methacrylate} [PEO-P(TMSPMA-NIPAM-AzoMA)] was synthesized via atom transfer radical polymerization (ATRP). The vesicles were obtained by self-assembly of the resulting block copolymer in a selective solvent, and then the PTMSPMA block was subjected to hydrolysis and polycondensation reaction to fix vesicle wall in the presence of triethylamine as a catalyst. The photo- and thermo- dual-responsive properties of the vesicles were investigated.

In this study, a amphiphilic copolymer, poly ((N-isopropylacrylamide)-co-acrylamide-co- (octadecylacrylate)-co-(Falate-(polyethyleneglycol)-(acrylicacid)))(P(NIPA-co-AAm-co-ODA-co-FPA)) micelles was synthesized by free radical random copolymerization. The obtained amphiphilic copolymers were self-assembled into micelles, which exhibited thermally sensitivity. LCST of the micelles was detected by uv-vis spectrophotometer. The diameter and morphology of micelles were determined by laser particle size analyzer (LPSA) and transmittance electron microscope (TEM), respectively. The micelle with a diameter of 60 nm and LCST of 40 oC was obtained by utilizing of ODA and the feed ratio of NIPA and AAm, respectively, which is satisfied for drug delivery in living body. The maximum DLC was achieved with the amount of ODA (180mg).
