“…Over the past two decades, studies of the CDSA of BCPs with a crystallizable core-forming block in selective solvents have expanded dramatically.

“…102 Moreover, studies of PFDMS BCPs with short corona -forming blocks showed that these materials yielded platelet micelles. 103 A wide range of crystallizable core-forming blocks other than PFDMS have now been employed to enable the formation of cylindrical/fiber-like micelles with crystalline cores and these include poly(3-hexylthiophene)), [104][105][106][107][108][109] poly(L-lactic acid) (PLLA), [110][111][112][113] polycaprolactone (PCL), 114,115 PEO, 116 PE, [117][118][119][120] poly(acrylonitrile), 121 poly(ferrocenyldimethylgermane) (PFDMG), 122 poly(ferrocenyldiethylsilane) (PFDES), 123 poly(ferrocenylmethylsilane)(PFMS), 124 PCL/PLLA, 125 poly(perfluoroethyloctylmethacrylate), 126,127 cholestorol-based polymers, 128 polyacetylene, 129,130 poly(pphenylene), 131 poly(3-heptylselenophene), 132 polyfluorene, [133][134][135] poly(pphenyleneethynylene), 136,137 poly(p-phenylenevinylene), [138][139][140][141][142] cyclic polypeptoids, 143 and poly(2-isopropyl-2-oxazoline).…”

This Perspective outlines recent advances concerning the formation and potential uses of block copolymer micelles, a class of soft matter-based nanoparticles of growing importance. As a result of rapidly expanding interest since the mid 1990s, substantial advances have been reported in terms of the development of morphological diversity and complexity, control over micelle dimensions, scale up, and applications in a range of areas from nanocomposites to nanomedicine.

“…Generally, block copolymers can be synthesized via two common strategies of sequential feeding and site transformation. The sequential feeding method means that block copolymer can be obtained by the sequential feeding of different monomers under the same kind of living polymerization mechanism such as anionic, cationic, group transfer, and living radical polymerization . The site transformation approach refers to synthesizing the block copolymers via different polymerization mechanisms, for which bi‐ and multifunctional initiators have been designed and prepared for attaining different polymerization mechanism demands of the monomers with different chemical structures .…”

A novel ABA triblock copolymer comprising double‐bond‐containing poly(phenoxyallene) (PPOA) and polystyrene (PS) segments was synthesized by sequential conventional free radical polymerization and atom transfer radical polymerization (ATRP) via the site transformation strategy. A new bifunctional initiator containing azo and Br‐containing ATRP initiating groups was prepared using 2‐bromopropionyl chloride, hydroquinone, and 4,4′‐azobis(4‐cyanopentanoic acid) as starting materials. Conventional free radical homopolymerization of phenoxyallene with cumulated double bond was performed in toluene to provide a polyallene‐based macroinitiator bearing ATRP initiating groups at both ends, which is stable under UV irradiation and free radical circumstances. PS‐b‐PPOA‐b‐PS triblock copolymer was then obtained by bulk ATRP of styrene initiated by PPOA‐based macroinitiator. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Narrowly dispersed diblock copolymers containing poly(methyl methacrylate) [PMMA] or poly(nonafluorohexyl methacrylate) [PF9MA] as the first block and poly(ferrocenylmethyl methacrylate) [PFMMA] as the second block, were prepared by anionic polymerization for the first time. Disordered bulk morphologies in the case of PMMA-b-PFMMA were observed and explained in terms of low Flory-Huggins interaction parameter (v 0.04). In the case of PF9MA-b-PFMMA hexagonally packed cylinder morphology (HEX) was substantiated from TEM and SAXS observations. Furthermore, high incompatibility between PF9MA and PFMMA blocks allowed for the formation of well-ordered ferrocene containing cylinders on silica substrate upon exposure of the thin films to a saturated solvent vapor. It was shown that the cylinder orientation, parallel or perpendicular to the surface, could easily be controlled by appropriate choice of the solvent and without the need for preliminary surface modification, for example by means of grafted brush layer.

A series of ABA triblock copolymers, consisting of double-bond-containing poly(phenoxyallene) (PPOA), poly(methyl methacrylate) (PMMA), or poly(butyl acrylate) (PBA) segments, were synthesized by sequential free radical polymerization and atom transfer radical polymerization (ATRP). A new bifunctional initiator bearing azo and halogen-containing ATRP initiating groups was first prepared followed by initiating conventional free radical homopolymerization of phenoxyallene with cumulated double bond to give a PPOA-based macroinitiator with ATRP initiating groups at both ends. Next, PMMA-b-PPOA-b-PMMA and PBA-b-PPOA-b-PBA triblock copolymers were synthesized by ATRP of methyl methacrylate and n-butyl acrylate initiated by the PPOA-based macroinitiator through the site transformation strategy. These double-bond-containing triblock copolymers are stable under UV irradiation and free radical circumstances.
