Computer-simulation der polykondensation von phenol mit formaldehyd

The polycondensation of phenol with formaldehyde to resole type phenolic resins has been studied using a kinetic model suitable for computer simulation. Important properties like residual amounts of monomers, number average degree of polymerization as well as degrees of branching and methylolation are calculated as functions of time for different values of initial molar ratios of phenol to formaldehyde and various rate constants. In addition the influence of intramolecular curing, due to formation of loops has been discussed in detail.
