PROCESS FOR THE PREPARATION OF CARBOXYLATED PROPYLENE POLYMERS A process for the preparation of carboxylated propylene homo- and copolymers, which comprises the reaction of a thermoplastic propylene homo- or copolymer with an azidosulfonyl- benzoic acid by mechanically mixing said polymer and said acid at a temperature of at least 180 free-radical initiator. The carboxylated polymers thus prepared have improved viscosity characteristics and can be used in polymer blends, e.g. with polyamides as well for the preparation of ionomers. |
