Abstract:
Amphiphilic 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 ( t BA) was then polymerized in the presence of the PMMA precursor, and PMMA -b- P t BA diblock copolymer with controlled molecular weight was prepared. Finally, amphiphilic diblock copolymer PMMA- b -PAA was obtained by hydrolysis of PMMA- b -P t BA. The formation of PMMA- b -PAA was confirmed by 1 H 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.
