1,6-Diamino-1,6-dideoxy-2,3,4,5-tetra-O-methyl-D-mannitol (and its L-iditol analogue) suitable for their utilization as monomers in the preparation of linear polyamides are described. Regio- and stereoregular polyamides of the AABB-type have been prepared by the active ester polycondensation method from these C(2) symmetric monomers and suberic and dodecanedioic acids. The resulting polyamides were
适合用作制备线性聚酰胺的单体的1,6-二氨基-1,6-二脱氧-2,3,4,5-四-O-甲基-D-甘露醇是(及其左旋糖醇类似物)描述。通过活性酯缩聚方法,由这些C(2)对称单体以及辛二酸和十二烷二酸制备了AABB型区域和立构规整型聚酰胺。得到的聚酰胺以合理的收率(70-60%)获得,并通过元素分析和红外光谱以及1H和13C NMR光谱进行表征。它们的M(w)和M(w)/ M(n)是通过GPC相对于聚苯乙烯标准品确定的。它们都是粘性的非结晶固体。
