40 Synthesis and linear rheological property of comb-like styrene-based polymers with a high degree of long-chain branching
关键字：Living polymerization; Comb-like copolymer; Linear rheological property
A series of model comb-like polymers (PSVS-g-PS) with high branching degree were synthesized by nucleophilic substitution reaction between iodinated copolymer of styrene (St) with 4-(vinylphenyl)-1-butene (VSt) (PSVSI, backbone) and living polystyrene lithium (PSLi, side chain). This method is a facile way for modular synthesis of graft copolymers based on living anionic polymerization and hydrozi...

Hydrolytic Degradation of Biobased Poly(butylene succinate-co-furandicarboxylate) and Poly(butylene adipate-co-furandicarboxylate) Copolyesters under Mild Conditions
关键字：biodegradable; biopolymers and renewable polymers; degradation; polyesters
It is indispensable to investigate hydrolytic degradation behavior to develop novel (bio)degradable polyesters. Biobased and biodegradable copolyesters poly(butylene adipate-co-butylene furandicarboxylate) (PBAF) and poly(butylene succinate-co-butylene furandicarboxylate) (PBSF) with BF molar fraction (/BF) between 40 and 60% were synthesized in this study. The hydrolyt...

DBU-Catalyzed Biobased Poly(ethylene 2,5-furandicarboxylate) Polyester with Rapid Melt Crystallization: Synthesis, Crystallization Kinetics and Melting Behaviors.
关键字：Biobased polymers, Poly(ethylene furandicarboxylate), Crystallization
Poly(ethylene 2,5-furandicarboxylate) (PEF) is in the spotlight as a newly emerged biobased
polyester in recent years. Usually, PEF exhibits very slow and weak melt crystallization behavior. In this study, PEF synthesis via transesterification polycondensation method catalyzed by 1,8-diazabicylo[5.4.0]undec-7-ene (DBU) as an organic nonmetallic catalyst was attempted...

Synthesis of High-Performance Polymers via Copper-Catalyzed Amination of Dibromoarenes with Primary Aromatic Ether Diamines
关键字：poly(imino ether ketone)s, heat-resistant polymer, copper-catalysis, foam.
In this paper, we introduce three high-performance polymers with similar structures, poly(imino ether ketone) (PIEK)s, which are synthesized by the ligand free copper-catalyzed C-N cross coupling reaction of aryl halides and primary aromatic diamines at moderate temperature. The influence of the solvents, base, temperature, and catalyst ligands on the polycondensation reaction is investigated. T...

Poly(9,9’-diheylfluorene carbazole) Functionalized with Reduced GrapheneOxide: Convenient Synthesis using Nitrogen-Based Nucleophiles and Potential Applications in Optical Limiting
关键字：graphene, nitrogencentered anions,nonlinear optics, nucleophilic addition, polymers
Covalently functionalized reduced graphene oxide (RGO) sheet was prepared by treating nitrogen-centered anions generated from poly(9,9’-diheylfluorene carbazole) (PCF) with
GO. The resultant hybrids with different chemical behavior were separated by centrifugation. The covalent modification was fully characterized by IR spectroscopy, UV/Vis spectroscopy, thermogravimetric analysis (TGA), Raman sp...
