High-molecular-weight polyamides are commonly known as nylon. Polyamides are crystalline polymers typically produced by the condensation of a diacid and a diamine. Chemical structures with effects of weathering, common stabilizers, manufacturers, and trade names along with typical end uses of the plastics are included besides extensive tabular and ...

New Insights into the Brill Transition in Polyamide 11 and Polyamide 6
Macromolecules, 2016The thermal stability of several crystal polymorphs in polyamide 11 (PA11) and polyamide 6 (PA6) has been investigated by means of in situ X-ray experiments. In the case of PA11, δ′ and α′ phases display a Brill transition far below the melting point. Both phases transform into a (pseudo)-hexagonal HT δ phase above 100 °C.

Studies on Molecular Composites of Polyamide 6/Polyamide 66
Macromolecular Rapid Communications, 2004AbstractSummary: 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.

Bulk of polyamide materials are used in the form of fibers, they have also become of some importance as specialty thermoplastics of particular use in engineering applications. The fiber-forming polyamides and their immediate chemical derivatives and copolymers are often referred to as nylons.

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.

Oxazoline‐containing compatibilizers for polyamide/SAN and polyamide/ABS blends
Journal of Applied Polymer Science, 2002AbstractPolyamide (PA) and acrylonitrile/butadiene/styrene copolymer (ABS) may appear as a mixture in the recycled plastic stream. The incompatibility of these blends results in a blend with poor mechanical properties. The aim of this work is to partially convert the nitrile groups of the acrylonitrile/styrene copolymer (SAN) into oxazoline groups by ...

Properties of Aromatic Polyamide and Polyamide-Hydrazide Membranes
1972The search for new and improved membrane compositions has continued on a large scale since the discovery of cellulose acetate as a desalination membrane by Reid and Breton[1], and subsequent improvements in flux demonstrated by Loeb and Sourirajan [2,3].

For the purposes of this chapter, polyamides are defined as polymers which contain recurring amide groups (-CO-NH-) in the main polymer chain. Various types of polyamides fall within this definition.

Many excellent reviews have been written on polyamides and their synthesis,1–13 and comprehensive (private) literature surveys are published by the Stanford Research Institute. Polyamides are mostly prepared by a stoichiometric stepwise reaction and belong to the group of condensation polymers (see also Volume 5, Chapter 1).

Adsorption of polyamides and polyamide–silane mixtures at glass surfaces
Surface and Interface Analysis, 2003AbstractThe individual and combined adsorption behavior of polyamides and two different silanes to multicomponent glass surfaces was probed with a combination of x‐ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and static contact angle measurements. Samples were analyzed with and without solvent rinsing to separate the weakly bound
