We report the synthesis of amphiphilic hetero-arm molecular brushes (AMBs), which were prepared by a combination of ‘grafting from’ and ‘grafting onto’ methodologies. First, styrene-terminated polyethylene glycol macromonomer (VB-PEG12, ∼666 g mol–1) was copolymerized with maleic anhydride (MAnh) to yield a polymer containing hydrophilic PEG chains and reactive (MAnh) groups. Subsequently, the reactive MAnh units in the obtained polymer were modified via a ring-opening reaction using primary alkyl amines, with different alkyl chain lengths, as the nucleophile. In situ ring closure yielded the styrene–maleimide-based AMB. The amphiphilic character of the AMBs was used for their self-assembly in different solvents. The effect of the ratio in hydrophilic to hydrophobic graft length on the morphology of the assemblies was studied using scanning electron microscopy.

The Cross

The aim of this study was to synthesize a serious of biodegradable elastomers by photocurable reaction as a potential biomaterial for the delivery of protein drugs. The macromonomers was prepared via ring opening reaction at 140°C later methacrylic acylated at 50°C. The optimal conditions were investigated and the property of the two macromonomer precursors were characterized via GPC and 1H-NMR. The cross-link degree of the elastomers can be adjusted by changing the concentration of photoinitiator (DMPA), furthermore influence the elastomers’ degradation rate. it could provide more appropriate choice for the elastomers in application.
