The present invention relates to the method for the preparation of the reactive thermoplastic compounds strengthened and the composition that obtained by this method, described composition comprises the external phase based at least one thermoplastic polymer, and the discontinuous phase, described reactive toughener and the described at least one thermoplastic polymer unmixing that are dispersed with in this external phase based on the reactive toughener of at least one.According to the method for the present invention for the preparation of thermoplastic compounds, wherein said at least one toughener is selected from: epoxy resin, the organopolysiloxane with SiH functional group, vulcabond or polyisocyanates and their mixture, and the method comprises: by being greater than 10n 2 sn -1 shearing rate under these are carried out reactively blending mutually, by described at least one toughener situ-formed graft, branching and/or be cross-linked on the chain of described at least one thermoplastic polymer, to be scattered in described external phase by described discontinuous phase with the form of tubercle, the number average bead diameter of described tubercle is less than 5 μm. |
