p-Toluenesulfonic acid → 3-Hydroxy-1-methacryloyloxyadamantane

Participants

Reaction Steps

1.4 g of the above obtained polymer was dissolved in 18.9 g of PGMEA in a round bottom flask. To the polymer solution approximately 40 mg of p-toluenesulfonic acid was added. After the acid was dissolved, 1.7 g of 1-methoxycyclohexene, 1.1 g of 2-methoxypropene and 0.5 g of dihydropyrane were added to the solution. The reaction was carried out at room temperature for a few days until the solution was clear. The reaction was then quenched with 5 g of basic active aluminum oxide. The quenched solution was filtered through 0.2 μm filter into a glass bottle.
