Nylon 66 and nylon 6 are two important members of a group of polymers known as polyamides. The structural units of a polyamide are joined together by an amide, -NH-CO-, group. A polyamide manufactured from aliphatic monomer(s) is commonly designated as nylon.

Improved Kinetic Rate Constants for Nylon 6, Nylon 6,6, and Nylon 6/6,6 Copolymer
Macromolecular Reaction Engineering, 2019AbstractNylon 6 and 6,6 literature data are collected over a wide range of water concentrations and temperatures (0 ≤ [W]0 ≤ 40.8 wt%, 200 ≤ T ≤300 °C) and used to fit parameters in an updated batch reactor model. The resulting copolymerization model uses side reactions to account for the complex influence of water on kinetics and reaction equilibria ...

Preparation and Characterization of Nylon 6/Nylon 6 Clay Fibers
Advanced Materials Research, 2012The drawing, tenacity and thermal properties of nylon 6 (NY6)/nylon 6 clay (NYC) composite fiber specimens prepared at varying NYC contents and drawing temperatures were investigated. The achievable draw ratio (Dra) values of NY6x(NYC)y as-spun fiber specimens initially increase in conjunction with NYC content, and then approach a maximum value, as ...

Vibrational spectra of nylon-6, nylon-6/6, nylom-11 and nylon-12 studied by terahertz spectroscopy
2012 37th International Conference on Infrared, Millimeter, and Terahertz Waves, 2012Terahertz absorption spectra were measured for nylon-6/6, nylon-6, nylon-11 and nylon-12 by Fourier transform far-infrared spectroscopy. Different spectral features among the four species were interpreted as the characteristics of crystalline conformations of nylons.

Polymer, 1997
Abstract Nylon 6-polyethersulfone (PES)-nylon 6 block copolymers were synthesized by anionic polymerization of ϵ-caprolactam using chlorine-terminated PES, a polymeric activator. The structure and properties of these block polymers were examined using infra-red, nuclear magnetic resonance, differential scanning calorimetry, transmission electron ...

Studies on crystallization kinetics of nylon 6-polyoxypropylene-nylon 6 copolymers
Journal of Polymer Research, 1997The crystllization kinetics of anionic-prepared nylon6-poly(oxypropylene) 1000-nylon 6 (NPN) block copolymers containing 1.20 to 8.76 wt% poly(oxypropylene)(POP) were studied. The thermograms of isothermal and nonisothermal differential scanning calorimetry of NPN block copolymers obtained were used for the study.

The synthesis of oligomers related to nylon 4 6 and nylon 6 6
Polymer, 1999Abstract A series of end-capped oligomers 17, 21, 25 and 28 related to nylon 4 6, and 39, 43, 47 and 50 related to nylon 6 6 have been prepared starting from adipic acid monoethyl ester 6, the α,ω-di-secondary diamines 8 and 29 and their mono end-protected derivatives 7 and 30, respectively, using the reactions of polypeptide chemistry. The formation

Isothermal crystallization behaviors of nylon-6 and nylon-6/montmorillonite nanocomposite
Materials Letters, 2004The effect of isothermal crystallization process on the crystal structure of nylon-6 and nylon-6/montmorillonite nanocomposite between 0 and 180 °C is examined using X-ray diffraction method. For the examined process, nylon-6 exhibits a gradual transition from γ- to α-phase with increasing crystallization temperature. The crystals of α-phase expand and
