Abstract
Abstract The initial stage of the phosphoric acid‐catalyzed polycondensation reaction of furfuryl alcohol and formaldehyde was studied. The overall kinetics of monomer‐consuming reactions were investigated in dependence of the initial monomer ratio and the temperature by analytical and physical (GPC) methods. A Suitable NMR technique was developed to determine the quantitative change in methylene and methylene ether linkages formed under different reaction conditions.
