ABSTRACT:
This invention concerns a process for obtaining homogeneous polymer compositions containing at least one olefin polymer and/or one arylvinyl polymer.
The process consists of adding, to either or to a mixture of both of these polymers, one or more block copolymers, containing one polyolefin and one polyarylvinyl sequence.
These polymer compositions provide homogeneous substances with properties combining those of the individual polymers, and in some mixtures these properties are considerably improved as the result of synergic phenomena.
