摘要 以氯甲基三氯硅烷为原料,甲醇、氯仿和石油醚为混合溶剂,在浓盐酸和无水三氯化铁为催化剂的条件下水解缩合制备了八氯甲基笼型倍半硅氧烷(CM-POSS)。利用FT-IR、GPC、1 H-NMR、29Si-NMR和XRD等技术对产物的结构进行了表征,并通过TGA研究了其热稳定性。结果表明产物为八氯甲基笼型倍半硅氧烷,且热稳定性良好。 Octa（chloromethyl） silsesquioxane（CM-POSS）was prepared by the hydrolysis condensation reaction of chloromethyl trichlorosilane catalyzed by the concentrated hydrochloric acid and anhydrous ferric chloride in the mixed solvent of methanol, chloroform and petroleum ether. The product was characterized by FT-IR, GPC, 1 H-NMR, 29 Si-NMR and XRD, the results showed that the product structure was octa（chloromethyl）silsesquioxane, and the product behaved good thermal stability by TGA.
