실험 절차

Isophorone diisocyanate [IPDI] (0.73 g, 0.003 moles) in 10 ml dry DMF was taken in a 100 ml two necked flask. Cardanol (1 g, 0.0033 moles) in 10 ml DMF was added drop wise with constant stirring under nitrogen. The reaction mixture was allowed to proceed under room temperature for 1 and a half hours. Then 3 drops of dibutyl tin dilaurate [DBTDL] was added as catalyst followed by drop wise addition of 2-Hydroxy ethyl methacrylate [HEMA][0.43 g, 0.003 moles]. It was left stirring at room temperature for further 2 hours. It was then heated to 55° C. and maintained at that temperature for 2 hours. Then, the contents were poured to 150 ml water and extracted with dichloromethane. It was then washed with plenty of water and dried in vacuum oven at 60° C. for 12 hours. Yield=90% (1.95 g)
