Porosity control in nylon‐6/nylon‐6, 6 membranes
Macromolecular Symposia, 1996AbstractThe possibility of porosity control in N6/N66 membranes prepared from N6/N66 blend solutions of calcium chloride – methanol mixture was investigated. For N6/N66 blend solutions at 10 °C and 20 °C, the four‐phase structure of solid, gel 1, gel 2 and solution was observed clearly in the pore formation process after adding water on a solution ...

A study on blends of nylon‐6 and nylon‐66
Journal of Applied Polymer Science, 1986AbstractBlending of nylon‐6 and nylon‐66 was carried out by coextrusion in the whole range of compositions with particular emphasis on small amounts of one polymer in the other. Most significant improvement in properties is achieved at low blend compositions in which the minor component remains amorphous while severely affecting the crystallization ...

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 ...

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.

Effect of nylon 6 inclusions on the crystalline morphology of polypropylene–nylon 6 blends
Journal of Applied Polymer Science, 2000Crystallization behavior and crystalline morphology of plain polypropylene (PP) and its blend with 0 to 30 wt % nylon 6 were studied by the hot-stage polarized light microscopy method. Radial growth rate and the size and number of PP spherulites were measured as a function of both the isothermal crystallization temperature and the nylon 6 content of ...

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 ...

Mechanical anisotropy in nylon 6 and nylon 6.6
Journal of Macromolecular Science, Part B, 1973Abstract The low-strain mechanical anisotropy of cold-drawn sheets of nylon 6 has been studied over a wide range of temperatures. At room temperature the mechanical anisotropy pattern is extremely complicated. It is suggested that this relates partly to the complex structural changes associated with drawing which reflect themselves in the ...

Vibration welding of nylon 6 to nylon 66
Polymer Engineering & Science, 2004AbstractVibration welding of dissimilar nylons is a promising technique for assembling complex components made of different polymers. The effects of pressure and meltdown on the tensile strength of nylon 6 (PA 6) to nylon 66 (PA 66) vibration welds were determined in this study using an experimental design and three weld geometries. Weld strengths were

Polymorphism of nylon‐6 in nylon‐6/nanoclay/functionalized polyolefin blends
Journal of Polymer Science Part B: Polymer Physics, 2007AbstractThe crystallization behavior of Nylon‐6 and the interaction in Nylon‐6/nanoclay/functionalized polyolefin blends were investigated by X‐ray diffraction and Fourier transform infrared spectroscopy. For samples without any thermal history, the interaction between Nylon‐6 and nanoclay or the interaction between Nylon‐6 and functionalized ...

Formation and properties of nylon-6 and nylon-6/montmorillonite composite nanofibers
Polymer, 2006Nanocomposite fibers of nylon-6 and an organically modified montmorillonite (O-MMT), Cloisite-30B, were prepared by electrospinning. Dispersion and exfoliation of O-MMT in nylon-6 were achieved by melt-extrusion in a twin-screw extruder prior to dissolving in aqueous formic acid for electrospinning.
