Claim:
1. A reactive thermoplastic composition that can be used to form a reactive system selected from the group consisting of interphase compatibilizing systems, systems for sizing fibers in composites and systems for dispersing fillers in thermoplastic phases, the composition comprising a continuous phase which is based on at least one thermoplastic polymer and dispersed in which is a discontinuous phase based on at least one reactive reinforcing chemical agent selected from the group consisting of epoxy resins, polyorganosiloxanes having SiH functional group(s), polyisocyanates and mixtures thereof, wherein this composition is free of any compatibilizing agent between said phases and comprises the product of an in situ reaction of grafting, branching and/or crosslinking, by a reactive compounding of these phases under a shear rate greater than 10 3 s −1 , of said at least one reinforcing agent onto the chain of said at least one thermoplastic polymer, so that the latter has (have), by this reaction, a grafted, branched and/or crosslinked structure, said discontinuous phase being dispersed in said continuous phase in the form of nodules having a number-average size of less than 5 μm with a maximum standard deviation of 0.5 μm.
