| 摘要 |
The invention relates to a process for preparing a composition comprising a vinylaromatic polymer matrix and particles of rubber, which comprises a step of polymerizing at least one vinylaromatic monomer in the presence of a rubber comprising a group which generates a stable free radical. The process makes it possible to obtain morphologies other than salami morphologies, such as the labyrinth, onion or capsule morphology, with the aim, for example, of enhancing the gloss of the high-impact vinylaromatic polymer.
