Modification of Butadiene -Acrylonitrile Rubber/ Poly(Vinyl Chloride) Blend Using Natural Rubber, Styrene-Butadiene Rubber, and Polybutadiene Rubber

open access: yes, 1987
Natural rubber, styrene-butadiene rubber, and polybutadiene rubber were used to replace part of the butadieneacrylonitrile rubber in a 70/30 butadiene-acrylonitrile rubber/ poly(vinyl chloride) blend. Such replacement up to 15% of the total weight of the

Application of Peroxide Curing Systems in Cross-Linking of Rubber Magnets Based on NBR and Barium Ferrite

open access: yesAdvances in Materials Science and Engineering, 2019
Rubber magnetic composites were prepared by incorporation of barium ferrite in constant amount—50 phr into acrylonitrile-butadiene rubber. Dicumyl peroxide as the curing agent was used for cross-linking of rubber magnets alone, or in combination with ...

Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

Thermally Induced Crosslinking in Blends of Poly(Vinyl Chloride) and Hydrogenated Acrylonitrile—Butadiene Rubber

open access: yes, 1993
A blend of Poly(vinyl chloride) (PVC) and hydrogenated acrylonitrile—butadiene rubber (HNBR) undergoes crosslinking at high molding temperatures in the absence of any external curing agents. This is evident from Monsanto rheometric, solvent swelling, and

Selective Oxidation of Primary Amines to Nitriles Catalyzed by the Ru‐Doped Hexagonal Perovskite SrMnO3

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
The selective oxidation of primary amines to generate nitriles provides a cost‐effective and atom‐economical synthetic approach that avoids the formation of harmful byproducts. However, achieving high yields under mild conditions remains challenging, due to the difficulty in efficiently activating the α‐CH bonds of amines and the multiple competing ...
