Synthesis of poly(α-methyl β-alanine)-poly(ε-caprolactone) [PmBA-(PCL)2] tri arm star polymer was accomplished by "click" chemistry. For this purpose, poly(α-methyl β-alanine) (PmBA) was synthesized from methacrylamide by hydrogen transfer polymerization (HTP). Terminally dibromo PmBA (PmBA-2Br) was obtained by using the end-group modification meth...

Composite catalyst of heteropolyacid ammonium salt, (NH4)3PW12O40, and SiO2 was prepared by sol–gel method. The resultant catalyst ((NH4)3PW12O40-SiO2, 3.38wt%) having W/Si molar ratio of 2/8 enabled to proceed ring-opening polymerizations of tetrahydrofuran (THF), ε-caprolactone (CL), and glycidyl phenyl ether (GPE) to give the corresponding poly(...

In this study, we prepared nitrogen-doped microporous carbons (NMCs) from two different benzoxazine monomers (AMBZ, AEBZ), each containing both azobenzene and carboxylic groups, through a simple and environmentally friendly process of ring-opening polymerization (ROP), calcination, and KOH activation. We synthesized the AMBZ and AEBZ monomers throu...

Traditional boron affinity materials usually capture cis-diol-containing molecules under alkaline condition, but some cis-diol-containing molecules, such as polyphenols, are unstable and easy to be oxidized and degraded under alkaline condition. Teamed boronate affinity (TBA) can specifically capture cis-diol-containing molecules under neutral cond...

Block copolymerization is already a proven technique to manipulate the properties of polymeric materials. Herein, our work presents a facile synthesis of high molecular weight polyglycolide-b-poly(L-)lactide-b-polyglycolide (b-PLLGA) triblock copolymers by ring-opening polymerization (ROP) in bulk at considerably low temperature. A series of ABA-ty...

Thermosensitive star-shaped eight-arm poly-2-alkyl-2-oxazolines (M = 21,000 g mol−1) was synthesized. The arms were gradient copolymers of 2-ethyl-2-oxazoline (EtOx) and 2-isopropyl-2-oxazoline (iPrOx). The more hydrophilic EtOx units prevailed near the calix[8]arene core. For comparison, model linear gradient copolymer (M = 3800 g mol−1) was inves...

In this work, we reported a simple two-step method for the synthesis of magnetic mesoporous epoxy resin (MMER), including one-pot template-free hydrothermal synthesis of nanoscale amine-functionalized magnetic nanoparticles (MN-NH2) and initiator-free ring-opening polymerization of epoxy resin. The resultant MMER was characterized in detail by tran...

The global pollution caused by plastics and microplastics is stimulating intense research towards more environmentally friendly materials, preserving the remarkable application characteristics of the currently available polymers. Among these, polyhydroxyalkanoates (PHAs) have been hailed as the solution to replace conventional, oil-based plastics. ...

Industrial lignin has a lower compatibility and processability than other polymers during the preparation of composites. To valorize the industrial lignin from spent liquor of alkaline pulping mills, polycaprolactone was grafted onto alkaline lignin to improve its compatibility and processability in this investigation. The lignin-g-polycaprolactone...
