  • Publication number: 20060099531
    Abstract: A process for preparing a blocked derivatized poly(4-hydroxystryrene)-DPHS 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; and (iv) reacting said polymer with a vinyl ether, a dialkyl dicarbonate, or a mixture of vinyl ether and a dialkyl dicarbonate to form the blocked DPHS.
