The effect of clay on the thermal degradation of polyamide 6 in polyamide 6/clay nanocomposites

Polymer, 2005
Abstract The degradation pathway of polyamide 6/clay nanocomposites was studied as a function of clay content. Well-dispersed polymer–clay nanocomposites can be easily obtained by simple melt blending between organically-modified clays and polyamide 6.

Ordnungszustände im system polyamid‐6 und polyamid‐6, 6

Makromolekulare Chemie. Macromolecular Symposia, 1986
AbstractBlends of PA‐6 and PA‐6,6 were studied by DSC for different conditions of crystallization. All samples were characterized by x‐ray diffraction. From dilute solution the components crystallize in separate modifications. In the melt both components are compatible. PA‐6‐ and PA‐6,6‐segments are linked together.

Effect of polyamide 6 on the mechanical behavior of thermoplastic polyurethanes/polyamide 6 blends

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2021
Ductility and tensile strength are among the basic mechanical properties of polymers. Generally, it is difficult to enhance the ductility without significantly reducing the tensile strength. In this study, thermoplastic polyurethane (TPU) is mixed with 0%, 2.5%, 5%, 7.5%, 10%, and 12.5% polyamide 6 (PA6).

Studies on Molecular Composites of Polyamide 6/Polyamide 66

Macromolecular Rapid Communications, 2004
AbstractSummary: A series of molecular composites of PA 6/PA 66 was synthesized via in situ polymerization. The impact resistance of PA 6 was improved dramatically by incorporating a minor amount of PA 66 (2–10 wt.‐%), without decreasing the tensile strength.

Crystallisation behaviour of Polyamide-6 and Polyamide-66 nanocomposites

Composites Science and Technology, 2006
The crystallisation properties of injection moulded Polyamide-6 and Polyamide-66 nanocomposites based on organophilic layered silicates were investigated by differential scanning calorimetry and X-ray diffraction to better understand the influence of the nanoplatelets on these two matrices.

Preparation and properties of polyamide 6/polypropylene–vermiculite nanocomposite/polyamide 6 alloys

Journal of Applied Polymer Science, 2002
AbstractPolypropylene–vermiculite nanocomposites can be achieved by simple melt mixing of maleic anhydride‐modified vermiculite with polypropylene. Maleic anhydride acts either as a compatibilizer for the polymeric matrix or as a swelling agent for the silicate.

Crystalline properties of injection molded polyamide-6 and polyamide-6/montmorillonite nanocomposites

Applied Clay Science, 2009
Abstract This paper presents a study of the crystalline properties of injection molded samples of polyamide-6 (PA6) and polyamide-6/montmorillonite nanocomposites (PA6 MMT). Processing conditions and tool temperature during injection molding affect the crystal structure and the crystallinity of the samples.

Axial fatigue behaviour of polyamide-6 and polyamide-6 nanocomposites at room temperature

Composites Science and Technology, 2008
Abstract Design against fatigue requires thorough understanding of the underlying fatigue mechanisms and factors influencing them. The objective of the present work is to study the effect of nanoclay addition on the temperature rise and modulus drop during cyclic loading in polyamide-6 and polyamide-6 base nanocomposite.

Processability of polysulfone improved by adding polyamide 6 and polysulfone‐polyamide 6 block copolymer

Journal of Applied Polymer Science, 2014
ABSTRACTAlthough polysulfone (PSU) is a potential thermoplastic engineering plastic with high heat resistance, good dimensional stability and excellent mechanical properties, its poor processability has greatly restricted its application in electrical, aerospace, and medical fields. In this work, polyamide 6 (PA6) and PSU‐PA6 block copolymer (PSU‐b‐PA6)
