POLYMERS MODIFIED BY MEANS OF A MODIFYING REAGENT AND METHOD FOR PRODUCING SAME

摘要

The invention relates to a chemically modified polymer and to a method for producing the chemically modified polymer, in particular chemically modified polyolefins. First, a polymer to be modified and additionally a modifying reagent are fed to a reaction zone of a reactor and then the polymer and the modifying reagent are fed through the reaction zone, wherein at the same time energy is input into the polymer such that the polymer is activated and a chemical reaction of the activated polymer with the modifying reagent into the modified polymer occurs as a result of the input energy. The dwell time of the polymer in the reaction zone and the temperature in the region of the reaction zone are selected in such a way that polymerization and depolymerization stay approximately in balance.
