Abstract

Cover: Chemoselective stepwise coupling between living polymers and a heterobifunctional linking agent renders feasible the synthesis of block copolymers that are not accessible by sequential monomer addition. This facile and efficient synthetic tool resembles the versatility of a Swissarmy knife, being a powerful strategy for accessing welldefined block copolymers. Further details can be found in the article by V. Bellas, M. Rehahn on page 320.

Equilibrium Melting Temperature of Poly(ferrocenyl dimethylsilane) in Homopolymers and Lamellar Diblock Copolymers with Polystyrene

“…The PS-b-PFDMS diblock copolymer was synthesized by sequential living anionic polymerization in glass reactors equipped with break-seals for the addition of the reagents (Scheme 1). [8,11,22] First, styrene was polymerized in cyclohexene at room temperature using the required amount of sec-BuLi. After completed conversion (%12 h), a solution of FS in cyclohexene was added by smashing the breakseal of the corresponding ampoule.…”

“…[1][2][3][4][5][6][7] Moreover, it counts among the very few metallopolymers accessible by living chain-growth protocols which give access not only to products of defined molar mass and narrow polydispersity but also to a broad variety of copolymer architectures: plenty of PFDMS block copolymers with, e.g., polystyrene (PS), [8][9][10][11] polyisoprene (PI), [12] poly(dimethyl siloxane) (PDMS), [8,12,13] poly(ethylene oxide) (PEO), [14] poly(methyl methacrylate) (PMMA), [15][16][17][18][19][20][21] and poly(2-vinylpyridine) [22] have been synthesized, and they have been shown to develop fascinating morphologies at the nanometer to micrometer scale. [2,7,23] Another important feature of PFDMS is its ability to crystallize.…”

Synthesis and characterization of PS‐b‐PDMS‐b‐PS triblock copolymer

“…[1][2][3] However, its application is limited because of its awful film-forming property, poor cohesion, and low-glass transition temperature, which induce the cumbersome curing process of PDMS and poor mechanical performance. [12][13][14][15] It is very little that block copolymers containing polysiloxanes were prepared, because polysiloxanes is susceptible to many reagents such as acid and alkali. Specifically, hybrid polymers containing PDMS have been reported for many different applications such as nanotechnology, electronics, filtration, two-dimensional liquid chromatography, and adsorption, among many others.…”
