“…Polyethers are condensation polymers and they have drawn a great deal of demand due to thermal stability, structural modification, versatile synthesis, and many applications such as anti‐freezing agent, detergents, cosmetics, ink, food flavoring, medicine, and pharmacology . In addition, different derivatives of polyethers such as poly(ether ketone), poly(ether sulfone), and poly(ether imide) were also prepared and reported in literature. Among the polyimide derivatives, poly(ether imide)s are the engineering polymers and they are predominantly used in industrial applications …”

The goal of this article was to synthesize a series of flexible polyimides containing ether linkage in main chain and clarified the effect of this ether linkage on some physical properties such as optical and thermal decomposition. Also, different functional group effects such as carbonyl (CO), hexa‐fluoro‐isopropylidene [C(CF3)2] and phenyl (C6H5) on these physical properties were evaluated. The structural characterization of poly(ether imide)s was performed using Fourier transform infrared, 1H‐nuclear magnetic resonance (NMR), and 13C‐NMR techniques. Optical band gap of polyimides was calculated in the range from 2.57 to 2.81 eV. Thermal characterization of poly(ether imide)s was carried out using thermogravimetry–differential thermal analysis and differential scanning calorimetry. Thermal stability of poly(ether imide)s was evaluated by initial decomposition temperature (Ton) and char. Ton value of polymers was determined in the range from 100 to 195 °C. In addition, glass transition temperatures of poly(ether imide)s were found between 144 and 148 °C. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46573.

Fiber reinforced polymers (FRPs) require a good match of fiber reinforcement and polymer matrix facilitating excellent thermal and mechanical properties. This contribution combines the mineral fibers glass and basalt with a novel silicatic hybrid polymer matrix formed during twin polymerization of 2‐(3‐Amino‐n‐propyl)‐2‐methyl‐4H‐1,3,2‐benzodioxasiline (APSI) as a novel amine hardener and the bisphenol A‐based epoxide BADGE. The resulting ternary hybrid material consists of a nanostructured and crosslinked epoxide, phenolic resin and polydialkylsiloxane network. In comparison to conventionally cured BADGE with IPDA (isophorone diamine), the glass and basalt fiber reinforced twin polymers showed a retarded combustion with a higher residual mass after oxidation. Moreover, the reinforcing effect with glass respective basalt was pronounced in case of APSI cured BADGE. The increased inorganic ratio in the composites due to in situ formation of polysiloxane species seems to affect beneficially FRPs thermal and mechanical properties by increasing the stiffness by 25% and the storage modulus by 260%.
