| dc.description.abstract | The possibility of synthesis of fast curing phenolic novolac has been studied under the catalyst of HCl/ Zn(AC)₂ . Synthesis of high-ortho novolac resins modified with different concentration (10, 20, 30 and 40 wt %) of biomass pyrolysis oil have been performed according to the reaction conditions of novolac production from pure phenol and formaldehyde. Curing reaction of resins indicated that resins modified with biomass pyrolysis oil (10 wt %) provide fast curing property with cure time ranges from 40 to 50 s and suitable softening point range from 85 °C,-95 °C,. The structure of fast curing novolac was characterized by FT-IR and DSC. | en_US |
