Zusammenfassung:	A process for preparing derivatized poly(4-hydroxystyrene) having a novolak type structure which comprises the steps of (i) supplying a solution of methanol containing 4-hydroxyphenylmethylcarbinol, (ii) subjecting said solution to an acid catalyzed displacement reaction for a sufficient period of time and under suitable conditions of temperature and pressure to convert substantially all of said carbinol to 4-hydroxyphenylmethylcarbinol methyl ether in solution, (iii) polymerizing said ether containing solution in the presence of a suitable acid catalyst for a sufficient period of time and under suitable conditions of temperature and pressure to form a novolak type polymer. New compositions of matter which comprise the derivatized poly(4-hydroxystyrene) prepared in the above manner and which have application in the electronic chemicals market such as in a photoresist composition, and in other areas such as in varnishes, printing inks, epoxy resins, copying paper, tackifiers for rubber, crude oil separators, and the like.
