    摘要: The invention relates to a method for producing hyperbranched polymers, said method being characterised in that compounds of general formula (1), wherein the variables are defined as follows, are reacted in the presence of a catalyst, optionally with at least one compound of general formula (1a) wherein the variables are also defined as follows: x represents sulphur or oxygen; R1 and R3 are the same or different and are selected from hydrogen, C1-C6 alkyl, C3-C12 cycloalkyl, C6-C14 aryl; R2 and R4 are the same or different and are selected from hydrogen, C1-C6 alkyl, C3-C12 cycloalkyl, C6-C14 aryl; Z1 and Z2 are the same or different and are selected from COOH and COOR6, the radicals R6 being the same or different and selected from C1-C6 alkyl, formyl, CO-C1-C6 alkyl; R5 is respectively the same or different and selected from C1-C6 alkyl and hydrogen; and n is a whole number between 2 and 10.
