Copolymerization of elemental sulfur (S8) with vinyl monomers to develop new polymer materials is significant. Here, for the first time, we report anionic hybrid copolymerization S8 acrylate at 25 °C, yielding a copolymer short polysulfide segments; i.e., each them consists only one four atoms. The formation longer segment would be ceaselessly disrupted by carbon anions through chain-transfer reaction. diacrylate was cross-linked and exhibited excellent mechanical properties, an ultimate...
The antifouling properties of traditional self-polishing marine coatings are mainly achieved based on their hydrolysis-sensitive side groups or the degradable polymer main chains. Here, we prepared a highly branched copolymer for coatings, in which primary chains bridged by fragments (poly-ε-caprolactone, PCL). Owing to partial complete degradation PCL fragments, remaining coating surface can be broken down and eroded seawater. Finally, polymeric is self-polished self-renewed. designed...
This study established an environmentally friendly hydroxyl–yne click polymerization, which provides a new strategy for the preparation of color-tunable unconventional luminescent materials.
Degradation or recycling of styrene-copolymers whose main chains are saturated carbon is very difficult under natural conditions.
A functional initiator monomer containing lipoic acid ester both with degradable disulphide bond and peroxide was designed synthesised. Here, the precursors are tert-butyl (isopropylbenzene) hydroperoxide, while dichloromethane (tetrahydrofuran) used as a solvent 4-dimethylaminopyridine (DMAP) N, N'-dicyclohexylcarbodiimide (DCC) were condensation agents. The structure purity of characterised by proton nuclear magnetic resonance (1H-NMR) high-performance liquid chromatography (HPLC)....
Two soluble polymers containing azobenzene chromophore in main chain were successfully synthesized from α-azide, ω-alkyne A−B type monomers, 3′-ethynylphenyl[4-hexoxyl(2-azido-2-methylpropionate)phenyl]azobenzene (EHPA) and 3′-ethynylphenyl[4-(4-azidobutoxy)phenyl]azobenzene (EAPA), via thermal 1,3-dipolar cycloaddition bulk. Compared to the obtained Cu(I)-catalyzed ("click" chemistry), showed good solubility common solvents like CHCl3 THF film-forming ability. The thermally stable up 330...
An approach to branched vinyl polymers through radical polymerization in the presence of 3-mercaptohexyl methacrylate (MHM) as chain transfer monomer is reported this paper. In case at styrene100–MHM5.0–AIBN2.0, molecular weight increased with conversion and reached a value >7.3 × 105 g/mol 99% conversion; addition, Zimm branching factor, g′, was less than 1 decreased conversion, when formation development supposed. The bridging units obtained polymer, generating from MHM, were cleaved yield...

Hyperbranched polymers with high molecular weights were synthesized by <italic>t</italic>-BuP<sub>2</sub>-catalyzed oxa-Michael addition polymerization of trifunctional hydroxyl and diacrylate monomers.
The ring-opening reaction of epoxides with alcohol and tertiary amines was studied. NMR spectroscopy analysis confirmed that glycidol has a different polymerization mechanism than other in the presence amines.
Development of a nonconjugated room temperature phosphorescence (RTP) system with lifetime longer than 1 s remains challenge. Here, we report RTP polymer composed amide-terminated hyperbranched polyether cross-linked boric acid, whose can reach up to 2.40 maximum absolute quantum yield 26.5%. Moreover, their phosphorescent emission wavelength be tuned from 517 585 nm by changing the excitation 300 480 nm, while afterglow color regulated blue yellow-red. Particularly, exhibits dual stimulus...
Injectable and self-repairing hydrogels with tunable gelation time have excellent application prospects in drug release tissue engineering. In this study, we synthesized the above through acylhydrazone bonds between polyacrylate containing aldehyde group azobenzene (P(Azo-co-EGMA)) P(N-isopropylacrylamide-co-acrylhydrazide) hydrazide (P(NIPAM-co-AH)). The (tsol–gel) could be controlled from a few seconds (<5 s) to several hours (20 h) by changing total polymer concentration or molecular...
In this study, nonconjugated hyperbranched poly(vinyl ether ester)s (HPVEEs) with carbon–carbon double bonds in their backbone were synthesized via bicyclo[2.2.2]-1,4-diazaoctane-catalyzed hydroxyl–yne click polymerization of triols diynes at 25 °C. Moreover, the branching behavior, structures, and properties HPVEEs correlation between structures performance analyzed by employing techniques such as size-exclusion chromatography, Fourier transform infrared spectroscopy, nuclear magnetic...
The amide bond is one of the most pivotal functional groups in chemistry and biology. It also key component proteins widely present synthetic materials. majority studies have focused on formation group, but its postmodification has scarcely been investigated. Herein, we successfully develop Michael additions to acrylate, acrylamide, or propiolate presence phosphazene base at room temperature. This addition much more efficient when secondary instead primary used under same conditions....
Polymerization behaviors and polymer branching structures in atom transfer radical polymerizations of styrene with 1,6-bismaleimidohexane (BMIH), tri-ethylene glycol dimethacrylate (tri-EGDMA) divinylbenzene (DVB) as the agents have been studied, mole ratio monomer to agent is 30/1.0. Their polymerization are quite different because levels interaction between agents. The charge complex effect BMIH causes core-formation. DVB system exhibits slowest evolution there no DVB. structure indicator...
