  摘要：

  高支化聚合物至少包含从二酸醇糖[1]中选择的至少一种无水糖相关化合物：（其中R是氢原子或具有1至30个碳原子的烃基，前提是nR相等或不相等，且nR中至少有一个R是氢原子，符号n为1至10的整数）和无水糖醇[2]：（其中R1、R2、R3和R4各自是氢原子或具有1至30个碳原子的烃基；前提是R1、mR2、pR3和R4相等或不相等，且所述mR2和pR3中至少有一个R2或R3是氢原子，符号m为0或1至20的整数，符号p为1至20的整数，前提是符号m+p为1至20的整数）或从二酸醇糖[1]和/或无水糖醇[2]中选择至少一种无水糖相关化合物，与从由通式[3]、[4]、[5]、[6]或[7]表示的无水糖中选择的至少一种糖化合物一起存在。高支化聚合物可以通过在阳离子或阴离子引发剂存在下聚合二酸醇糖或无水糖[1]或[2]或聚合二酸醇糖或无水糖[1]或[2]和无水糖的情况下制备。

  The hyperbranched polymers are at least one anhydrosugar-related compound selected from the dianhydrosugar alcohol [1]: (wherein R is hydrogen atom or a hydrocarbon group having from 1 to 30 carbon atoms, provided that nR's are equal to or different from one another and at least one R of nR's is hydrogen atom, and symbol n is an integer from 1 to 10) and the anhydrosugar alcohol [2]: (wherein each of R1, R2, R3 and R4 is hydrogen atom or a hydrocarbon group having from 1 to 30 carbon atoms; provided that R1, mR2's, pR3's and R4 are equal to or different from one another and at least one R2 or R3 of said mR2's and pR3's is hydrogen atom, respectively; and symbol m is zero (0) or an integer from 1 to 20 and symbol p is an integer from 1 to 20, provided that symbol m+p is an integer from 1 to 20) or at least one anhydrosugar-related compound selected from the dianhydrosugar alcohol [1] and/or the anhydrosugar alcohol [2] with at least one sugar compound selected from the anhydrosugar as represented by the general formula [3], [4], [5], [6] or [7]. The hyperbranched polymers are readily prepared by polymerizing the dianhydrosugar alcohol or the anhydrosugar [1] or [2] or the dianhydrosugar alcohol or the anhydrosugar [1] or [2] together with the anhydrosugar in the presence of a cationic or anionic initiator.
