“…XRD graph of sepiolite modified resol resins were given Figure . The values of PFR and sepiolite are compatible with the results of the literature . The diffraction patterns of the resols pre‐Þred at temperatures below 500 °C show a single halo at about 20°, being essentially similar to that of unÞred sample …”

Alendronic acid modified resol nanocomposite resins (AA‐PFNCRs) and sepiolite modified resol nanocomposite resins (SEP‐PFNCRs) have been synthesized by in situ method in the presence of base catalyst. Additionally, the synergistic effects of alendronic acid and sepiolite clay (AA‐SEP‐PFNCR) on the resol resin have been studied. The structure, morphology, and thermal properties of these nanocomposites have been investigated by Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), and X‐ray Diffraction (XRD). The results demonstrated the interactions between the fillers and resol resin. Thermal properties of nanocomposite resins were improved due to alendronic acid and sepiolite. The obtained samples were also characterized morphologically by Scanning Electron Microscope (SEM). © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43807.

“…( P A P E ) g e I = 0.333 (2) Thus nonstoichiometric compositions should not reach the gel point provided the ratio of amine hydrogens to epoxide groups ( r ) is less than l/3 for excess diepoxide or l/r is less than 1/3 for excess diamine. Bearing this in mind several polymers with compositions within these limits were prepared from DDM and DGEBA and their Mn's measured.…”

SynopsisA study of some of the average chemical properties of a variety of diepoxide-diamine network polymers has been carried out. The weight fraction of sol, the quantity of unreacted epoxide in the sol, and the number-average molecular weight of the sol have been measured for polymers prepared from both stoichiometric and nonstoichiometric ratios of diamine and diepoxide. Theoretical expressions for these quantities have been calculated using the methods recently developed by Macosko and Miller. These relationships were found to give close agreement with the experimental behavior.* Part I1 is on pp. 1571-1580 of this issue.
