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.

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)

HALS in polyamide 6 polymerization

Macromolecular Symposia, 2003
AbstractThe 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,

Physical Properties of Polyblends of Polyamide 6 Polymer with Cationic Dyeable Polyamide 6 Polymer

Journal of Polymer Research, 2004
Polyamide 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%.

Microinjection molding of polyamide 6

Polymers for Advanced Technologies, 2014
Processing polymers by microinjection molding (μIM) generate specific constraints upon the polymer melt such as high shear stress and rapid cooling, leaving a mark upon the microstructure of the micropart. The present work compares the morphology and structure of polyamide 6 samples produced by melt extrusion and μIM.

Reinforcement of Polyamide 6 with Nanoparticles

Macromolecular Symposia, 2007
AbstractPolyamide 6 has been reinforced by in situ polymerization of ε‐caprolactam by using either 2 wt % of multiwall carbon nanotubes of two different diameters and length or 2 wt % functionalized nonporous Stöber silica. The carbon nanotubes were synthesized by catalytic chemical vapor deposition of ethylene over two different supports: iron ...
