一般描述

臭氧、OH自由基和NO(3)自由基与异氰酸烯丙酯(AIC)气相反应的速率常数已有研究[1]

异氰酸烯丙酯是一种有机硫化合物,可用于生物可降解葡聚糖-异氰酸烯丙酯-乙胺/聚乙二醇-二丙烯酸水凝胶的合成与鉴定。[2]

应用

异氰酸烯丙酯用于:
  • 与pHPMA的2°羟基反应制备烯丙基-pHPMA(烯丙基-聚N-(2-羟丙基)甲基丙烯酰胺)。[3]
  • 通过苯乙烯的双向阴离子聚合反应(bidirectional anionic polymerization)制备含烯丙基的triBCP前体。前体用于合成聚异氰酸烯丙酯-嵌段-聚苯乙烯-嵌段-聚异氰酸烯丙酯(PAIC-b-PSt-b-PAIC)。[4]
