Synthesis of poly(arylene benzimidazole) sulfone (PABIS) and preparation of hollow PABIS microspheres
4,4’-Di(benzimidazolyl)benzene sulfone, as the monomer, is very readily available by the reaction of 4,4’-dicarboxydiphenyl sulfone with o-phenylenediamine, and poly(arylene benzimidazole) sulfone (PABIS) has been synthesized by the condensation polymerization of bis(4-fluorophenyl) sulfone with di(benzimidazolyl)benzene sulfone via an N–C coupling reaction. The structure of the polymer was c...

Intermolecular Hydrogen Bonding of Poly(Imino Imino Ketone Ketone)
Molecular dynamics calculations were made of the distance from the hydrogen atom of the imino group to the distance of the oxygen atom of the carbonyl group of poly(imino imino ketone ketone) (PIIKK). The results showed that theoretically there was hydrogen bond formation between the hydroxyl group and the carbonyl group of PIIKK. The existence of the hydrogen bonding between the polymer chains ...

Multiple Chain Packing and Phase Composition in Regioregular Poly(3-butylthiophene) Films
On the basis of different film preparation conditions, we address the phase composition and thiophene main-chain and butyl side-chain organization of three regioregular poly(3-butylthiophene) (P3BT) samples prepared by drop-casting. These samples are readily identified by wide-angle X-ray diffraction (WAXD) with the structural P3BT polymorphs commonly referred to as forms I, I′, and II. Here, we ...

Effect of Surface Modification of Cellulose Nanocrystal on Nonisothermal Crystallization of Poly(β-hydroxybutyrate) Composites
Carbohydrate Polymers, 2017, 157C, 1821-1829.
ABSTRACT:
Ring-opening
polymerization of L-lactide from
cellulose nanocrystal (CNC) surface yielded polylactide-grafted CNC (CNC-g-PLA). The structure of as-obtained CNC-g-PLA was characterized by FT-IR, 1H
NMR, XPS and XRD. The crystallization behavior and lamellar structure of poly(β-hydroxybutyrate)
(PHB) in the presence of pr...

Synthesis of Poly(2-aminothiazole) for Selective Removal of Hg(II) in Aqueous Solutions
Conducting poly(2-aminothiazole) (PAT) was simply green synthesized by a chemical oxidation method using 2-aminothiazole as the monomer and copper chloride as the oxidant in aqueous solution. The effects of reaction time and oxidant/monomer molar ratio on the polymerization yield were investigated. The PATs were characterized by FT-IR, 1H NMR, UV–vis, gel permeation chromatograms (GPC), and scann...

Poly(monothiocarbonate)s from the Alternating and Regioselective Copolymerization of Carbonyl Sulfide with Epoxides
CONSPECTUS: Carbonyl sulfide (COS) is an air pollutant that causes acid rain, ozonosphere damage, and carbon dioxide (CO2) generation. It is a heterocumulene and structural analogue of CO2. Relevant to organic synthesis, it is a source of C=O or C=S groups and thus an ideal one-carbon (C1) building block for synthesizing sulfur-containing polymers through the simila...

The Role of Nanocrystalline Cellulose during Crystallization of Poly(ε-caprolactone) Composites: Nucleation Agent or Not?
Composites Part A: Applied Science & Manufacturing, 2017, 92, 17-26.
ABSTRACT:
Poly(ε-caprolactone) (PCL) composites with pristine nanocrystalline
cellulose (NCC) and acetylated nanocrystalline cellulose (aNCC) (with 1.85±0.15 degree of substitution) were prepared. Different
roles of NCC and aNCC to the
crystallization of PCL were explored. NCC acts as the ...

Mechanical Properties of Thermoplastic Polyester Elastomer Controlled by Blending with Poly(butylene terephthalate)
Polymer Testing, 2016, 55C, 152-159.
ABSTRACT:
Thermoplastic polyester elastomer (TPEE) blends with poly(butylene terephthalate) (PBT) were prepared by melt compounding for the phase morphology and mechanical property studies. Although PBT is immiscible with the continuous soft poly(tetramethylene glycol) (PTMEG) phase of TPEE, it is miscible with the discrete hard PBT...

Structure and Properties of Poly (Butylene Succinate) Filled with Lignin: A Case of Lignosulphonate
A new kind of blend material was prepared by the incorporation of lignosulfonate calcium (LS), as the filler, into biodegradable poly(butylene succinate) (PBS), as the polymeric matrix, with the process of melt mixing and subsequent compression molding. The nucleation of LS improved the crystalline properties of the PBS component in the blends. Combined with the rig...
