The inimitable geometry of novolac type phenolic resin (phenolic) and the strong inter-association cause the special microstructure in which the poly(hydroxyl ether of bisphenol A) (phenoxy) is sporadic in phenolic-rich region. Thermodynamic properties of the anomaly blend of phenolic and phenoxy were predicted by the Painter-Coleman Association Model. A modified method was used to obtain the equilibrium...
The hydrogen bond formation between novolac type phenolic resin (phenolic) and polyhydroxyl ether of bisphenol A (Phenoxy resin) were verified by infra-red (i.r.), gel permeation chromatography (g.p.c.) and nuclear magnetic resonance (n.m.r.). The i.r. spectrum of the free hydroxyl group of the blend shows a maximum absorption area with 25 wt% phenoxy which coincides with the lowest point of...
