PROCEDURE
实验过程
Isophorone diisocyanate [IPDI] (0.73 g, 0.003 moles) in 10 ml dry DMF was taken in a 100 ml two necked flask. 2-Hydroxy ethyl methacrylate [HEMA][0.43 g, 0.003 moles] 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 cardanol (1 g, 0.0033 moles) in 10 ml DMF. 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)
