在这项工作中描述了多功能硫醇角鲨烯的合成。使用硫羟乙酸，通过硫醇-烯偶联反应对角鲨烯的六个双键进行官能化。所得硫代乙酸酯水解，得到相应的六硫醇角鲨烯SQ6SH。该化合物进一步分别与氰尿酸三烯丙酯、三丙烯酸季戊四醇酯和二甘醇二乙烯基醚进行光聚合。实时 FTIR 动力学表明，除了硫醇-烯光聚合之外，还发生了烯单体的均聚。当SQ6SH与上述不饱和单体进行本体光聚合时，得到柔性薄膜。
In this work is described the synthesis of a multifunctional thiolated squalene. Thiol-ene coupling reactions were employed to functionalize the six double bonds of squalene, using thiolacetic acid. Hydrolysis of the resulting thioacetates, rendered the corresponding hexathiolated squalene SQ6SH. This compound was further photopolymerized separately with triallyl cyanurate, pentaerythritol triacrylate and diethyleneglycol divinyl ether. Real Time FTIR kinetics revealed that homopolymerization of the ene monomers took place in addition to the thiol-ene photopolymerization. Flexible films were obtained when SQ6SH was photopolymerized in bulk with the above mentioned unsaturated monomers.
