A number of resins have been prepared by the condensation of substituted benzoic acid with formaldehyde in the presence of different acids and bases as the catalyst. The intrinsic viscoSity and Huggin's and Kraemer's constants of the resins were determined. The solubility behavior of the resins was

A number of resin copolymers have been prepared by condensing a-picoline, y-picoline, and lutidine separately with hydroxy acetophenone, hydroxy, amino, chloro benzoic acids, and toluic acid in the presence of sodium hydroxide and succinic acid as catalyst. The resins were characterized by infrared
The reactivity ratios, thermal behavior, and the bacteriocidal properties of the resins prepared from substituted acetophenones, i.e., rn-aminoacetophenone, o-hydroxyacetophenone, and rnhydroxyacetophenone, have been investigated. The results obtained from the bacteriocidal studies are found to be q
## Abstract A new microwave‐assisted method of synthesis of solid epoxy resins (SER) with desired epoxy‐groups content is described. The method is based on the polyaddition of 4,4′‐isopropylidenediphenol (BPA) to a lower‐molecular‐weight epoxy resin [Rütapox 0162, epoxy value (EV) = 0.57 mol/100 g]
