  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 R 1 , R 2 , R 3 and R 4 is hydrogen atom or a hydrocarbon group having from 1 to 30 carbon atoms; provided that R 1 , mR 2 's, pR 3 's and R 4 are equal to or different from one another and at least one R 2 or R 3 of said mR 2 's and pR 3 '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.
