英文: Abstract: Methanesulfonic acid method was used to prepare five acylated chitins.Except heptanoyl chitin, four of them,i.e.acetyl chitin,propionyl chitin,butyryl chitin and hexanoyl chitin,had high degree of substitution(from 1.5 to 2.0)and exhibited lyotr
中文: 文摘:四种羧酰化甲壳素即乙酰化、丙酰化、丁酰化和己酰化甲壳素在二氯乙酸溶液中均呈现胆甾型溶致液晶相.临界浓度随侧基长度增加而略有增加,衍生物的临界浓度明显都比原甲壳素高许多,这些规律都可以用链刚性的变化来解释.四种羧酰化甲壳素在剪切时均能形成条带织构,而且能形成条带织构的最低浓度有明显差别,随侧基长度增加而提高,进一步表明侧基较长,液晶性减少.
