12. Synthesis and Characterization of Poly(ether sulfone)-graft-polydimethylsiloxane Copolymers
Novel poly(arylene ether sulfone) (PAES) polymers containing polydimethylsiloxane (PDMS) side chains were synthesized and characterized with NMR and Fourier transform infrared spectroscopy. The thermal properties of the copolymers were evaluated with differential scanning calorimetry and thermogravimetric analysis. The polymers showed perfect thermal stability, as the decomposition temperatures we...

10. Synthesis and characterization of novel cyano-functionalized poly(aryl ether ketone)s
A series of cyanophenyl-substituted poly(aryl ether ketone)s (PAEKs) have been successfully synthesized from two new bisphenol monomers, (3,4-dicyano) phenylhydroquinone and (4-cyano) phenylhydroquinone respectively, and the thermal behaviour and the solubility have been characterized. These polymers exhibited high glass transition temperatures and excellent thermal stability. The glass transition...

4. Synthesis and properties of soluble fluorinated poly(ether imide)s with different pendant groups
Two types of new fluorinated diamine monomer, [1,4-(4-amio-2-trifluoromethyl-phenoxy)-2-(3''''''''-trifluoromethylphenyl) benzene (III)] and [1,4-(4-amio-2-trifluoromethyl-phenoxy)-2-(3''''''''-methylplienyl) benzene (IV)] were synthesized and polymerized with aromatic dianhydrides. A series of soluble poly(ether imide)s (PEIs) were prepared from the diamines and dianhydrides by two-step chemical ...

2. Synthesis and Characterization of Poly(ether ether ketone)s with (2,5‐dihydroxy)phenyl Side Group
A new monomer, (2,5-dimethoxy)phenylhydroquinone (DMPH), was prepared in a two-step synthetic procedure. One aromatic poly(ether ether ketone)s with 2,5-dimethayy phenyl side group (DMP-PEEK) was synthesized via an aromatic nucleophilic substitution reaction with 4,4''''''''-difluorobenzopherone (DFB). Poly(ether ether ketone)s with 2,5-dihydroxy phenyl side group (DHP-PEEK) was obtained via hydro...

Poly(trimethylene monothiocarbonate) from the Alternating Copolymerization of COS and Oxetane: A Semicrystalline Copolymer
ABSTRACT: A semicrystalline poly(trimethylene monothiocarbonate) (PTMMTC) has been synthesized via the selective and alternating copolymerization of carbonyl sulfide and oxetane. This reaction was catalyzed by (salen)CrCl accompanied by organic bases over a wide range of
temperatures from 40 to 130 °C. PTMMTC is shown to exhibit similar crystallization behavior to high-de...

Synthesis, Thermal Properties and Thermoresponsive Behaviors of Cyclic Poly(2-dimethylamino)ethyl Methacrylate)s
This study aims at physicochemical properties of thermo- and pH/CO2-responsive cyclic homopolymers. Three examples of cyclic poly(2-(dimethylamino)ethyl methacrylate)s (PDMAs) are synthesized by combining the reversible addition–fragmentation chain transfer process and the Diels–Alder ring-closure reaction. After cyclization, the glass transition temperature significantly increases (ΔTg = 51....

Nucleation Role of Basalt Fibers during Crystallization of Poly(ε-caprolactone) Composites
Industrial & Engineering Chemistry Research, 2017, 56(10), 2746-2753.
ABSTRACT:
Basalt fiber (BF) filled poly(ε-caprolactone) (PCL) composites were prepared by melt mixing for the crystallization study.
The results reveal that both pristine and treated BFs have remarkable nucleation effect on the crystallization of PCL,
but the latter has higher nucleation activity...

Synthesis by free radical polymerization and properties of BN-polystyrene and BN-poly(vinylbiphenyl).
Free radical polymerization of B-vinyl-and B-styryl-functionalized azaborinine monomers gives well-defined hybrid polymers that were fully characterized by multinuclear NMR and GPC analysis; their solubility, thermal characteristics, and photophysical properties are dramatically different from those of the all-carbon polystyrene analogues.

Soluble N-substituted poly(benzimidazole imide)s via C-N coupling reaction
Novelheat-resistantN-substitutedpoly(benzimidazole imide)s (PBIIs)withgoodsolubilitywere synthesized via aC?Ncoupling reaction. A model reaction was carried out to assist in determining the optimal reaction conditions for the polymerization and to elucidate the chemical structures of the polymers. The structures of the resulting polymers were characterized by means of Fourier transform infrared ...

Rational design of a fluorescent poly(N-aryleneindole ether sulfone) switch by cation–π interactions
Semirigid poly(N-aryleneindole ether sulfone) (PESIN) as a fluorescence emission on–off switch has been successfully achieved via the cation–π interactions. The adjustment of the protonation/ deprotonation status of pyridine that regulates the formation of cation–π interactions is definitely the determinant.
