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, 2021Ductility 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). The results show that the sample containing 100%

Crystallisation behaviour of Polyamide-6 and Polyamide-66 nanocomposites
Composites Science and Technology, 2006The 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.

Axial fatigue behaviour of polyamide-6 and polyamide-6 nanocomposites at room temperature
Composites Science and Technology, 2008Abstract 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.

Preparation and properties of polyamide 6/polypropylene–vermiculite nanocomposite/polyamide 6 alloys
Journal of Applied Polymer Science, 2002AbstractPolypropylene–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.

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.

Stabilization of polyamides—I. The efficiency of antioxidants in polyamide 6
Polymer Degradation and Stability, 1996The influence of antioxidants on the thermooxidation of hydrolytically and anionically prepared polymers of 6-hexanelactam was studied. Oxygen consumption was followed during oxidations and the changes in molecular weight and in the content of carboxyl groups were evaluated.

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)

Physical Properties of Polyblends of Polyamide 6 Polymer with Cationic Dyeable Polyamide 6 Polymer
Journal of Polymer Research, 2004Polyamide 6 (PA 6) and cationic dyeable polyamide 6 (CD-PA 6) polymers were blended mechanically in the proportions of 75/25, 50/50, 25/75 in a melt twin-screw extruder to prepare three PA 6/CD-PA 6 polyblended polymers. The molar ratio of dimethyl 5-sulfoisophthalate sodium salt (SIPM) for CD-PA 6 polymer was 2%.

HALS in polyamide 6 polymerization
Macromolecular Symposia, 2003AbstractThe use of Hindered Amine Light Stabilizers (HALS) directly in polyamide 6 polymerization can cause some problems. The following two problems were the focus of our project:1) We investigated, from a theoretical point of view, the results of introducing directly one of the precursors of HALS into polyamide 6 polymerization. For the investigation,
