A highly rigid diamine monomer derived from naturally occurring myo‐inositol and its use for polyamide synthesis

25-Jul-2016 | Atsushi Sudo, Shou Sugita, Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT A rigid diamine was synthesized from myo‐inositol, a naturally occurring cyclic hexaol, and used as a monomer to synthesize polyamides. myo‐Inositol was treated with 1,1‐dimethoxycyclohexane to yield a bisketal bearing two hydroxyl groups, and from this bisketal, the target diamine ...

Synthesis and tunable properties of oligoaniline‐functionalized polyamides

12-Jul-2016 | Mingying Yin, Ying Yan, Justin P. Cole, Erik B. Berda, Fangfei Li, Xincai Liu, Ce Wang, Danming Chao, Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT Electroactive polyamides containing dense oligoaniline functionalizations (PAs) were synthesized via oxidative coupling polymerization followed by postpolymerization functionalization, and exhibit excellent solubility, good thermal stability and reversible electroactivity. Interesting ...

Chemical Sensors Based on New Polyamides Biobased on (Z) Octadec‐9‐Enedioic Acid and β‐Cyclodextrin

17-May-2016 | Lisday Duarte, Sananda Nag, Mickaël Castro, Elena Zaborova, Mickaël Ménand, Matthieu Sollogoub, Véronique Bennevault ..., Macromolecular Chemistry and Physics, 2016

The synthesis of new biobased polyamides from different β‐cyclodextrin monomers and the (Z) octadec‐9‐enedioic acid is investigated. The aim of this study is to design different sensors, having different sensibilities and selectivities to a set of various volatile organic compounds (VOC) ...

Solid‐state 13C, 15N and 29Si NMR characterization of block copolymers with CO2 capture properties

02-May-2016 | Faiz Ullah Shah, Farid Akhtar, Muhammad Saif Ullah Khan, Zareen Akhter, Oleg N. Antzutkin, Magnetic Resonance in Chemistry, 2016

Natural abundance solid‐state multinuclear (13C, 15N and 29Si) cross‐polarization magic‐angle‐spinning NMR was used to study structures of three block copolymers based on polyamide and dimethylsiloxane and two polyamides, one of which including ferrocene in its structure. Assignment of most of ...

Ultrastrong, Transparent Polytruxillamides Derived from Microbial Photodimers

22-Apr-2016 | Seiji Tateyama; Shunsuke Masuo; Phruetchika Suvannasara; Yuuki Oka; Akio Miyazato; Katsuaki Yasaki; Thapong Teerawat ..., Macromolecules, 2016

Ultrastrong and transparent bioplastics are generated from fermented microbial monomers. An exotic aromatic amino acid, 4-aminocinnamic acid, was prepared from a biomass using recombinant bacteria, and quantitatively photodimerized, and diacid and diamino monomers that were both characterized by ...

Synthesis and thermal, optical and morphological characterization of oligomeric polyamides based on thiophene and alkyl/phenyl‐silane moieties. Study of the electrospun deposition process

15-Apr-2016 | Ignacio A. Jessop, Alain Tundidor‐Camba, Claudio A. Terraza, Carmen M. González‐Henríquez, Luis H. Tagle, Journal of Applied Polymer Science, 2016

ABSTRACT Polyamides were synthesized from a thiophene‐containing diamine by direct polycondensation with organosilane acyl dichlorides. The obtained polymers had good solubility in common organic solvents and THF, with TDT10% values upper than 400 °C and Tg between 150 and 180 °C. Combination ...

Isothermal and nonisothermal crystallization kinetics of fully bio‐based polyamides

15-Apr-2016 | Miaomiao He, Tao Wei, Liqun Zhang, Qingxiu Jia, Polymer Engineering and Science, 2016

We studied the crystallization behaviors of bio‐based BDIS polyamides synthesized from the following biomass monomers: 1,4‐butanediamine (BD), 1,10‐decanediamine (DD), itaconic acid (IA), and sebacic acid (SA). Isothermal crystallization, melting behavior, and nonisothermal crystallization of ...

Biorenewable blends of polyamide‐4,10 and polyamide‐6,10

05-Apr-2016 | Christopher S. Moran, Agathe Barthelon, Andrew Pearsall, Vikas Mittal, John R. Dorgan, Journal of Applied Polymer Science, 2016

ABSTRACT Biobased polymers hold the promise of greatly improved sustainability metrics. In this study, semicrystalline polymer blends are formulated between two partially biorenewable polyamides. Polyamide 4,10 (PA410) is melt mixed with polyamide‐6,10 (PA610). Physical properties of the ...

Azo-Containing Polymers with Degradation On-Demand Feature

05-Apr-2016 | Mathieu A. Ayer; Yoan C. Simon; Christoph Weder, Macromolecules, 2016

Molecules comprising aliphatic azo moieties are widely used as radical polymerization initiators, but only a few studies have explored their usefulness as stimuli-responsive motifs in macromolecular constructs. The controlled degradation of azo-containing polymers has indeed remained largely ...

Organic‐acid mediated bulk polymerization of ε‐caprolactam and its copolymerization with ε‐caprolactone

31-Mar-2016 | Ana Sanchez‐Sanchez, Andere Basterretxea, Daniele Mantione, Agustin Etxeberria, Cristina Elizetxea, Amaia de la Call ..., Journal of Polymer Science Part A: Polymer Chemistry, 2016

ABSTRACT Polyamides (PA) constitute one of the most important classes of polymeric materials and have gained strong position in different areas, such as textiles, fibers, and construction materials. Whereas most PA are synthesized by step‐growth polycondensation, PA 6 is synthesized by ring ...
