Influence of the Silicate Modifier Nature on the Structure and Properties of Polycaproamide

Abstract

The influence of the nature and amount of the nanosized polyvinylpyrrolidone silicate modifier obtained as a result of the combined sol-gel transition on the supramolecular structure, as well as physical, mechanical and thermo-physical properties of polycaproamide has been determined. The modifier has proved to significantly increase the degree of crystallinity of polymer, and thus tensile strength at break, surface hardness and thermal resistance of a composite.

Modified Densified Waste of Expanded Polystyrene and Its Blends With Polyamide 6

“…For a blend compound with 10 wt% modified EPS, the absorption band expansion for Amide I and Amide II is so large that it can be assumed that a sufficiently developed spatial structure is formed by hydrogen bonds between amide and carbamate. Consequently, PVP, which is contained in a modified EPS, is actively involved in the redistribution of intermolecular hydrogen bonds in the polyamide to form new carbamate groups .…”

“…The investigation indicates that the nature and content of the polystyrene additive component significantly affects the morphological features of polyamide materials, primarily, the compatibility between the components of the mixture, which, along with the moisture content, is a key factor of the physical‐mechanical properties of these materials. EPS modified with PVP, unlike the degassed sample, leads to some increase in strength parameters of PA‐6, apparently due to higher compatibility between components of the mixture, which, in our opinion, is due to the intermolecular bonds redistribution under the influence of PVP .…”

Adsorptive Modification of High-Dispersed Magnesium Hydrosilicate

“…In our previous investigations [10,11] we established that the synthesized powders are greatly hydrated. The water loss is 31.…”

Properties of the Composites Made of Glauconite and Polyaniline in Aqueous Solutions of Phosphoric Acid

“…Among the nucleation additives that can be used to influence the morphology of polymeric materials, fine metal-containing silicate materials have been widely used [10,11]. These additives can directly affect the size of crystalline formations, the degree of crystallinity and the performance characteristics of polymeric materials.…”
