A facile one-pot synthetic approach toward the realization of star polymers made of degradable carbonate cores is reported. The synthetic strategy involved triethylborane-activated anionic copolymerization of a difunctional epoxide with CO2 initiated

Novolac polymers bearing varying proportions of propargyl and phthalonitrile groups on the same backbone and capable of self and co-curing to a thermally stable matrix have been synthesized. Spectral and thermal studies gave evidence for both homopol

The influence of propargyl groups on the thermal polymerization of phthalonitrile groups has been examined through reaction of a blend of a bisphthalonitrile viz . 2,2-bis(4-phthalonitrile oxy phenyl)propane and a bispropargyl ether viz . 2,2-bis(4-p

Graphene oxide (GO) possessing hydroxyl and epoxy groups was synthesized by a modified Hummer's process and was found to conform to the empirical formula C0.801[epoxy]0.190[OH]0.009. GO was examined as a curative for amino novolac phthalonitrile (APN

Novolac resins bearing both cyanate and phthalonitrile groups in different proportions in the same backbone were synthesized and characterized. The resin was thermally cured to a network. Differential scanning calorimetric studies showed that cyanate

Self cure promoting, amine-containing novolac–phthalonitrile (APN) resins of varying compositions were synthesized and characterized. APN possessing amine functionalities reduced the cure initiation temperature from 310 °C (typical of pure phthalo

Novolac–phthalonitrile polymers bearing a controlled concentration of phthalonitrile groups were synthesized by condensation of novolac with 4-nitrophthalonitrile. The cure characteristics monitored by DSC and rheometry indicated acceleration of th
