    摘要： A process for preparing hyperbranched polymers comprises reacting compounds of the formula I where X is sulfur or oxygen, R1 and R3 are identical or different and are hydrogen, C1-C6 alkyl, C3-C12 cycloalkyl or C6-C14 aryl, R2 and R4 are identical or different and are hydrogen, C1-C6 alkyl, C3-C12 cycloalkyl, C6-C14 aryl, Z1 and Z2 are identical or different and are COOH or COOR6, the radicals R6 being identical or different and being C1-C6 alkyl, formyl or CO—C1-C6 alkyl, R5 identically or differently at each occurrence is C1-C6 alkyl or hydrogen, and n is an integer from 2 to 10, optionally with at least one compound of the formula Ia where the variables are as defined above, in the presence of a catalyst.
