摘要通过聚二氯磷腈（PDCP）与含酚钠基团的炭黑反应，研究了炭黑表面接枝聚有机腈的反应。以氨基磺酸为催化剂，通过六氯环三嗪的溶液开环聚合制备了聚偏二氯乙烯（PDCP）。通过在甲醇中用氢氧化钠处理炭黑表面的酚羟基，实现了在炭黑上引入酚钠基团。通过在炭黑表面引入苯酚钠基团，再用苯氧基取代聚二苯氧基磷腈（PDPP）中的氯原子，成功地将PDPP接枝到炭黑表面。在30°C下，12 h后，接枝到炭黑上的百分比增加到206%。结果表明，炭黑表面只有1.4%的酚钠基团被用于接枝聚合物链，因为接枝聚合物链对表面的封闭。聚（二氨基苯基磷腈）
Abstract The grafting of poly(organophosphazenes) onto carbon black surface by the reaction of poly(dichlorophosphazene) (PDCP) with carbon black having sodium phenoxide groups was investigated. PDCP was prepared by the ring-opening polymerization of hexachlorocyclotriphos-phazene in solution using sulfamic acid as a catalyst. The introduction of sodium phenoxide groups onto carbon black was achieved by treatment of phenolic hydroxyl groups on the surface with sodium hydroxide in methanol. Poly(diphenoxyphosphazene) (PDPP) was successfully grafted onto carbon black by the reaction of PDCP with sodium phenoxide groups introduced onto the surface followed by the replacement of chlorine atoms in PDCP with phenoxy groups. The percentage of grafting onto carbon black increased to 206% at 30°C after 12 h. It was found that only 1.4% of sodium phenoxide groups on carbon black surface was used for the grafting of PDCP because of the blocking of the surface by grafted polymer chains.
