摘要
以甲基丙烯酸羟乙酯、溴丙炔和癸硼烷等为原料制得1-甲基丙烯酰氧乙氧甲基碳硼烷(PMAC),再依次与二甲基氯硅烷、氢氧化钠与磷酸二氢钠的缓冲溶液和三甲基氯硅烷反应,通过还原、取代得到目标化合物1-甲基丙烯酰氧乙氧甲基-2-(1,1,1,3,3-五甲基二硅氧烷基)碳硼烷(PMASC)。以FT-IR和~1H NMR鉴定了目标化合物的结构,由含碳硼烷桥基的硅氧烷丙烯酸酯单体PMASC对真丝织物进行接枝改性。当PMASC接枝率为34.4%时,800℃下接枝真丝织物的质量保留率为34.2%,高于未处理真丝织物的质量保留率(13.9%)。接枝处理后真丝织物的耐热性能得到改善。
Using hydroxyethyl methacrylate （HEMA）, propargyl bromide and decaborane as the raw ma- terials, 1-methacryloxyethyloxamethyl carborane （PMAC） was synthesized as an intermediate product and then followed by reduction and substitution reaction, the target monomer of 1 -methacryloxyethyloxamethyl-2- （ 1,1, 1,3,3-pentamethyldisiloxanyl） carborane （PMASC） was successfully prepared. The monomer PMASC was characterized by FT-IR and 1H NMR and then was used to modify silk fabrics. When the graft yield was 34. 4% ,the mass retention of grafted silk fabric was up to 34.2% under 800~C ,which was higher than 13.9% of the blank sample. Result showed that the modified silk fabrics with higher graft yield exhibited an improved heat-resistance.
