[1] Synthesis and characterization of cured allyl/propargyl ether novolac resins / B. Boris, K. Denis, B. Alexander et al. // Journal of chemistry and chemical engineering. — 2013. — no. 7. — P. 199–208. А new kind of modified thermoset resins were synthesized by phase-transfer Williamson reaction from novolac resin and mixtures of allyl- and propargyl chlorides. The compositions of the resins were defined by 1H NMR spectroscopy and the dependence of the cured materials properties on the composition was established. Increase of a propargyl content resulted in char yield raise and the maximum value had been found for propargylated resin—58%. DSC (differential scanning calorimetry)-analysis of the resins has demonstrated that exothermic enthalpy of the curing process could be adjusted by varying the content of propargyl and allyl groups in the resin.
