Key statement: A method for manufacturing a rubber composition includes kneading a rubber component, an inorganic filler and a thioester-based silane coupling agent, and adding a vulcanizing agent and one or more compounds selected from the group of an imide compound and an N-oxyl compound to a mixture of the rubber component, the inorganic filler and the thioester-based silane coupling agent such that the vulcanizing agent and the imide compound and/or the N-oxyl compound are kneaded with the mixture, including the rubber component, the inorganic filler and the thioester-based silane coupling agent.
[USPRwire, Thu Oct 18 2018] Polyimide polymers are derived from monomers of imide group, a functional group comprising two acyl groups.
The imide moiety with its aromatic backbone confers to the polymer enhanced mechanical strength, chemical resistance, optical properties, and thermal stability [1-4].
If the cyclic amide-glutamic acid is not formed then reaction seems to proceed towards byproduct formation with the cyclic imide as the major product.
Hence imide modified epoxy resins by either physical blending or chemical reactions have been reported to show good flame retardant properties.
In our reported work, the gelation properties of some cholesterol imide derivatives consisting of cholesteryl units and photoresponsive azobenzene substituent groups have been investigated [19].
The wettability of paper surfaces with adsorbed nanoparticles can be controlled by tuning the chemical and topographical surface parameters: the water contact angles were found to increase at higher imide content as determined by Raman spectroscopy (depending on synthesis and thermal treatment), and higher average surface roughness determined by AFM (depending on the deposition method).
The independent industry-focused international news portal, a division of Industrial Leaders said the publication promotes suppliers of a wide variety of generic families of plastic materials such as Acetal, Proprietary, Polybutadiene (PBR), Acrylonitrile Styrene Acrylate (ASA), Acrylic, Phenolic, Polystyrene (PS), Polyvinyl Chloride (PVC), Polyamide (Nylon), Thermoplastic Elastomer (TPE), Polyethlene (PE), Dicyclopentadiene (DCPD), Alkyd, Polyester, Silicone, Polycarbonate, AMS, Epoxy, DAP, Polyurethane, SAN, Styrene Acrylonitrile (SAN) as well as PAEK, Polyether Imide, PCL and other types of plastics and rubber.
[1] These polymers are characterized by their thermal and mechanical stability [2] due to presence of rigid imide ring in the back bone.
The film comprises a thermoplastic resin with a substituted or non-substituted imide group at a side chain of the resin and a thermoplastic resin with a substituted or non-substituted phenyl group and a nitrile group at a side chain of the resin.
Although styrene maleic anhydridye (SMA) copolymers are used today as sizing agents, little research has been carried out on some new styrene maleimide resins, or SMA imides. Relatively inexpensive, SMA imide resins can be dissolved easily and can be used in the headbox.
