Abstract
The present invention relates to a composition comprising a multistage polymer and a (meth)acrylic polymer, its process of preparation, and its use. In particular, the present invention relates to a composition comprising a multistage polymer in form of polymeric particles made by a multistage process and a (meth)acrylic polymer, while the (meth)acrylic polymer possesses a medium molecular weight. The present invention also relates to polymer composition comprising polymeric particles made by a multistage process comprising at least two stages and a (meth)acrylic polymer with a medium molecular weight, its method of preparation, its use as impact modifier in polymer compositions for composites comprising thermosetting resins or thermoplastic polymers and compositions and articles comprising it.
