Participants

Reaction Steps

50.0 g of the resin synthesized in Reference Example 2 was dissolved in 500 ml of acetone. After adding 3.0 g of potassium carbonate, 0.60 g of potassium iodide and 3.13 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 15% of the hydroxyl groups were ethyletherified and 5% of the hydroxyl groups were tert-butoxycarbonylmethyletherified.
