A process for preparing a polyhydroxystyrene having a novolak type structure which comprises the step of polymerizing a mixture of carboxylic acid and at least one substituted phenyl carbinol whose formula is (I), wherein (a) R1 is selected from the group consisting of H, alkyl C1-C20, substituted and unsubstituted phenyl, and C(O)R8 (where R8 is alkyl C1-C20); (b) R2 is selected from the group consisting of H and alkyl C1-C20; and (c) R3-R7 are each independently selected from the group consisting of H, alkyl C1-C20, OR9 (where R9 is H, alkyl C1-C20), esters thereof, or substituted and unsubstituted phenyl), halogen, BZT, nitro, or amino, with the proviso that at least one of R3-R7 is OR9, in the presence of a suitable catalyst for a sufficient period of time and under suitable conditions of temperature and pressure to form said novolak type polymer.
