Tetramethylpiperidine-containing copolymers

Ethylene-based copolymers which are suitable as flow improvers for mineral oil middle distillates are composed of

Ethylene-based copolymers and their use as flow improvers in mineral oil

Polyolefins are thermomechanically degraded in a twin-screw extruder without a downstream degradation apparatus, at from 300.degree. to 550.degree. C. and from 1 to 100 bar and in average residence times of the reaction mixture of from 0.5 to 10 minutes, by a process in which the pressure in the twin-screw extruder is changed periodically or aperiodically with a fluctuation of from 0.5 to 30 bar. The novel process is particularly suitable for the degradation of polypropylene.

Thermomechanical degradation of polyolefins

A curable molding material comprises a coherent phase of a free-radical curable, unsaturated polyester resin in which finely particulate polyolefin particles are dispersed as disperse phase, the two phases being chemically bound to one another at the interfaces by ionic bonds.
