HYPER-RAMIFIED POLYCARBONATE, PROCESSES FOR PREPARING HYPER-RAMIFIED POLYCARBONATES, THERMOPLASTIC OR THERMO-RIGID AND POLYOXYMETHYLENE, AND USE OF ONE OR MORE HYPER-RAMIFIED POLYCARBONATES
HYPER-RAMIFIED POLYCARBONATE, PROCESSES FOR PREPARING HYPER-RAMIFIED POLYCARBONATES, THERMOPLASTIC OR THERMO-RIGID AND POLYOXYMETHYLENE, AND USE OF ONE OR MORE HYPER-RAMIFIED POLYCARBONATES
HYPER-RAMIFIED POLYCARBONATE, PROCESSES FOR PREPARING HYPER-RAMIFIED, THERMOPLASTIC OR THERMO-RIGED POLYCARBONATES, AND USE OF ONE OR MORE HYPER-RAMIFIED POLYCARBONATES. Hyperbranched polycarbonates having stabilizing groups, prepared by reacting (a) at least one compound having at least three alcoholic hydroxyl groups per molecule with (b) at least one reagent of formula I (c) and at least one reagent of formula X ^ 3 ^ - (A ^ 1 ^) ~ mX ^ 4 ^, wherein the variables are defined as follows: X ^ 1 ^, X ^ 2 ^ are identical or different and are selected from halogen, C ~ 1 ~ -C ~ 10 -alkoxy, C ~ 6 -C ~ 10-aryloxy and OC (= O) -halogen, X3-3 is a functional group selected from OH, SH, NH-2 ~, NH-C -1C-4-alkyl, isocyanate, epoxy, COOH, COOR? 12?, C (= O) -OC (= O), C (= O)? C1, R? 12? Is C? 1? ~ -C ~ 4 ~ alkyl or C ~ 6 ~ -C ~ 10 ~ aryl, A ^ 1 ^ is a spacer or single bond, m is zero or one, X ^ 4 ^ is a group selected from phenolic groups benzophenones, aromatic amines and nitrogen-containing heterocyclic groups, in each case substituted or unsubstituted.
