Abstract

A detailed kinetic model for the novolac-type phenol-formaldehyde polymerization has been proposed in terms of five reactive sites. These sites have been shown to have different reactivities. Mass-balance equations for homogeneous, continuous-flow, stirred tank reactors (HCSTR) for each of the species have been written, and these have been solved numerically. A comparison of the results with those for the batch reactor shows that, for a given residence time, smaller but more polydispersed and branched chains are formed.
