Abstract
Phenolic oligomers were prepared by Friedel-Craft polymerization from different phenols with dichloro methane and 1,2-dichloroethane. The samples were characterized byir spectra, viscosity measurement and thermal analysis by differential scanning calorimeter (dsc). The number average molecular weight (\(\bar M_n \)) was determined by vapour pressure osmometry (vpo) and by conductometric titration.
