AbstractA novel phosphorus‐containing aralkyl novolac (Ar‐DOPO‐N) was prepared from the reaction of 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) first with terephthaldicarboxaldehyde and subsequently with phenol. The chemical structures of the synthesized compounds were characterized with Fourier transform infrared, 1H and 31P NMR, and ...

The structure‐property relationship of novolac cured epoxy resin/clay nanocomposites
Polymer Engineering & Science, 2008AbstractIntercalated or exfoliated novolac cured epoxy resin nanocomposites were prepared with two different kinds of layered silicates – montmorillonite (PK‐802) and nontronite (PK‐805). The bifunctional modifiers (PI/BEN or MI/BEN) are used to modify the clays for improvement of the properties of polymer where benzalkonium chloride (BEN) acts as a ...

Studies on the adhesive properties of solid elastomer-modified novolac epoxy resin
International Journal of Adhesion and Adhesives, 2000Abstract Adhesive properties like lap shear strength and T-peel strength of novolac epoxy resin modified with carboxyl terminated butadiene acrylonitrile (CTBN) solid resin and cured with two different curing agents namely, dicyandiamide (DICY) and 3,3′-diaminodiphenyl sulphone (DDS) were evaluated using aluminium adherends.

Polystyrene‐modified novolac epoxy resin/clay nanocomposite: Synthesis, and characterization
Polymers for Advanced Technologies, 2019A polystyrene‐modified epoxidized novolac resin/montmorillonite nanocomposite was fabricated and characterized successfully. For this purpose, novolac resin (NR) was epoxidized through the reaction of phenolic hydroxyl group with epichlorohydrin in super basic medium to produce epoxidized novolac resin (ENR). Afterward, a polystyrene was synthesized by

Thermal degradation of nadic methyl anhydride‐crosslinked novolac epoxy resin
Journal of Polymer Science Part A-1: Polymer Chemistry, 1968AbstractThe physicochemical high‐temperature reactions of a nadic methyl anhydride‐cross‐linked novolac epoxy resin were investigated by means of differential thermal analysis, thermogravimetric analysis, and by other analytical procedures. The thermogravimetric study revealed that decomposition involving weight loss occurred in two stages.

Preparation and properties of novolac epoxy resins containing polycyclic aromatic hydrocarbons
Polymers for Advanced TechnologiesAbstractTo meet the demands of high‐density and miniaturized integrated circuits, electronic packaging materials need to have excellent properties. One approach to enhance the performance is to design novel structures. In this study, two novolac oligomers containing naphthalene Naphthalene novolac oligomer (NPF) and biphenyl Biphenyl novolac oligomer ...
