摘要

用环戊基三氯硅烷合成不完全缩合三羟基硅氧烷［(C5H9)7Si7O9(OH)3］，再以乙烯基三氯硅烷和不完全缩合三羟基硅氧烷为原料，以四氢呋喃和三乙胺为混合溶剂，通过“顶角-戴帽”反应合成了笼型单乙烯基倍半硅氧烷，即1

13-七环戊基-15-乙烯基笼型倍半硅氧烷(VinylPOSS)。利用FTIR、1H NMR、29Si NMR、13C NMR、元素分析、WAXD和TGA表征了VinylPOSS的结构及热稳定性。研究结果表明VinylPOSS的产率随着反应时间的增加而提高，当反应时间为10 h时，产率高达90%；其在弱极性溶剂中具有较好的溶解性，5%失重温度为283℃，800℃残留率为56%，具有较高的热稳定性。研究了VinylPOSS和高含氢硅油(HHSF)的反应性，结果表明VinylPOSS能与含氢硅油发生α、β加成反应

且以β加成为主。

Abstract

Monovinyl-functionalized silsesquioxane cage

13-heptacyclopentyl-15-vinyl silsesquioxane(VinylPOSS)

was prepared via the corner capping reaction of incompletely condensed silsesquioxanes

(C5H9)7Si7O9(OH)3

with vinyltrichlorosilane.VinylPOSS was characterized by FTIR

1H NMR

29Si NMR

13C NMR

elemental analysis

WAXD and TGA.The yield of VinylPOSS increased with reaction time

when vinyltrichlorosilane reacted with (C5H9)7Si7O9(OH)3 for 10 h

the yield was 90%.VinylPOSS has good solubility in weak polar solvent

and it shows good thermal stability

its temperature with 5% decomposition is 283℃ and the temperature with 56% residue is 800℃.The reactivity of VinylPOSS with high hydrogen-containing silicone fluid (HHSF) was investigated.It can be reacted with HHSF by Michael additions at both α- and β- positions

and the reaction is mainly β-addition.
