以9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO)、缩水甘油、二正丁基氧化锡和二硫化碳为原料,合成出一种新型的含磷螺环原碳酸酯(DSOC).经红外光谱、核磁分析和元素分析对合成产物的结构进行表征后,作为抗收缩剂和阻燃剂用于环氧树脂(E-51)中,在三氟化硼乙胺络合物的催化作用下与 E-51进行共聚.结果表明,随着 DSOC 加入量的增加,环氧树脂的收缩率下降,当 DSOC 的加入量为10％(质量分数)时,材料的收缩不仅消失了,还表现出稍微的膨胀.DSOC 的加入不仅提高了材料的阻燃性能,还使材料的冲击强度和粘结强度得到改善.

A novel spiroorthocarbonate (DSOC)was synthesized through the reaction of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO ),2,3-epoxy-1-propanol,dibutyltin oxide and carbon disulfide.The structure of DSOC was confirmed by FT-IR,1 H NMR spectra and elemental analysis.Then it used as anti-shrinkage additives and flame retardant in the cationic polymerization of epoxy resins (E-5 1).It was found that shrinkage decreased with increased concentration of DSOC.At 10wt% of DSOC,not only the shrinkage of ep-oxy resins was eliminated,but a small level of volume expansion was also achieved.The flame retardancy and mechanical properties of modified epoxy resins were also investigated.
