Reaction Steps
50.0 g of the resin synthesized in Reference Example 14 was dissolved in 500 ml of acetone. After adding 10.9 g of potassium carbonate, 2.2 g of potassium iodide and 9.9 g of tert-butylchloroacetate, the solution thus obtained was refluxed for 10 hours. Thereafter, same post-treatment as those in Reference Example 15 was repeated to obtain poly(p-vinylphenol), wherein 6% of the hydroxyl groups were ethyletherified and 16% of the hydroxyl groups were tert-butoxycarbonylmethyletherified. The weight average molecular weight of this resin is 30,400 and its molecular weight distribution is 1.19.
