Abstract

The present invention relates to a process for producing a bimodal or multimodal mixture of amorphous polyolefins having a different molar mass, in which at least one amorphous polyolefin having a high molar mass is brought into contact and mixed with at least one amorphous polyolefin having a low molar mass in solution and the solvent is subsequently removed.
