Abstract The controlled polymerization of α-methylene-γ-butyrolactone (MBL, a naturally occurring sesquiterpene lactone found in tulips) was performed by nitroxide mediated polymerization (NMP) using the alkoxyamine Dispolreg 007 as the initiating system at 80 °C in 50 wt% DMSO. Features of a reversible-deactivation radical polymerization...

Abstract As a functional material, polyurethane elastomers have found different applications in a variety of fields such as flexible electronics and smart coatings, but due to the damage during use, they are often endowed with self-healing properties. However, conventional intrinsically self-healing polyurethanes often don't balance excellent...

Abstract A series of molecular brushes with a polyfluorene (PF) backbone and polymethacrylic acid side chains of varying lengths were prepared by atom transfer radical polymerization. The structure and composition of the synthesized compounds were confirmed by 1H NMR and IR spectroscopy. Effect of the length of the backbone on spectral and...

Abstract In this study, we report the synthesis of 3-, 4-, and 6-arm star poly(ionic liquid)s (PILs) (specifically, star poly(vinylbenzyl methylimidazolium bis(trifluoromethane)sulfonimide) (poly(VBMIm-TFSI))) via reversible addition-fragmentation chain transfer (RAFT) polymerization with a core-first approach, followed by quaternization and...

Abstract Soft tissues, such as muscle could autonomously grow through re-alignment and/or -combination of collagen nanofibrils upon the mechanical training. This adaptive capability is highly expected in artificial materials, particularly in hydrogel actuator. In order to avoid the failure for devices by suffering from the accumulated mechanical...

Abstract Designing the catalysts to get high molecular weight polyethylene is an art. The catalysts bearing imine functionality derived from 8-arylnaphthyl amines are more impressive and attractive in this regard. In this work, we synthesize 2,4-dibenzhydryl-8-(3,5-dichlorophenyl)naphthalen-1-amine to condense with picolinaldehyde, pyridine-N-oxide-2-carbaldehyde...
