METHOD FOR PRODUCING MODIFIED PLASTICS HAVING REDUCED CHAIN LENGTHS AND COMPOSITIONS THAT CAN BE PRODUCED THEREWITH

摘要

The invention relates to a method for producing modified plastics, in particular modified polyolefins, wherein plastics to be modified are fed to a friction zone and the plastics are conducted through the friction zone and at the same time friction energy and thermal energy are applied to the plastics, wherein the friction energy is produced by dispersing elements that rotate sufficiently quickly so that at least in the area of the friction zone, in which the plastics to be modified are fed, the plastics to be modified are decomposed into modified plastics by the applied friction energy, wherein the modified plastics have a molecular weight distribution having less than 5 wt % of polymers having a molecular weight of less than 1400 g/mol.
