Participants

Reaction Steps

50.0 g of the resin synthesized in Reference Example 3 was dissolved in 500 ml of acetone. After adding 9.6 g of potassium carbonate, 1.93 g of potassium iodide and 10.0 g of tert-butylchloroacetate, the solution obtained was refluxed for 10 hours. Thereafter, same post-treatment as that of Reference Example 5 was carried out to obtain hydrogenated poly(p-vinylphenol) wherein 6% of the hydroxyl groups were ethyletherified and 16% of the hydroxyl groups were tert-butoxycarbonylmethyletherified.
