Acrylonitrile Block and Graft Copolymers
This paper presents a review of the methods available for preparing block and graft copolymers in which one component is acrylonitrile. Methods using polymer ions and polymer radicals are considered together with a useful new technique based on reactions of nitrile groups with amide compounds of group IV transition metals. Because of its polarity and its unusual solubility properties, a polyacr...
متن کاملModular Synthesis of ABC Type Block Copolymers by ‘‘Click’’ Chemistry
Heterotelechelic polystyrene (PS), poly(tert-butyl acrylate) (PtBA), and poly (methyl acrylate) (PMA), containing both azide and triisopropylsilyl (TIPS) protected acetylene end groups, were prepared in good control (Mw/Mn 1.24) by atom transfer radical polymerization (ATRP). The end groups were independently applied in two successive ‘‘click’’ reactions, that is: first the azide termini were f...
متن کاملSurface-induced phase transitions in ultrathin films of block copolymers.
We study theoretically the lamellar-disorder-lamellar phase transitions of AB diblock and tetrablock copolymers confined in symmetric slitlike pores where the planar surface discriminatingly adsorbs A segments but repels B segments, mimicking the hydrophobic/hydrophilic effects that have been recently utilized for the fabrication of environmentally responsive "smart" materials. The effects of f...
متن کاملMicellization of block copolymers
This article deals with recent progress including the author’s work in the field of block copolymer self-assembly in solution and on solid surfaces. The synthesis methods for producing block copolymers with well-defined structures, molecular weights and composition are outlined with emphasis on ionic and controlled free radical polymerization techniques. A general overview of the preparation, c...
متن کاملSelf-Assembly of Block and Graft Copolymers in Organic Solvents: An Overview of Recent Advances
This review is an attempt to update the recent advances in the self-assembly of amphiphilic block and graft copolymers. Their micellization behavior is highlighted for linear AB, ABC triblock terpolymers, and graft structures in non-aqueous selective polar and non-polar solvents, including solvent mixtures and ionic liquids. The micellar characteristics, such as particle size, aggregation numbe...
