Abstract: This work describes the way of preparation of polymer blends by polymerization (PBA-co-DAP) in melt of PMMA under intensive stirring. The original macromolecular network is exposed to shear stress. When critical deformation force is exceeded, the network begins to rapture. It is assumed that microgels appear also due to coalescence P(BAC-co-DAP) molecules and due to their crosslinking during the synthesis. The foils of PMMA blend containing 19.9 mass % of P(BAC-co-DAP) should be of fourteen-times increased non-notches impact resistance in comparison with foils of original PMMA. The influence of shear tension on the course of polymerization and properties of the prepared blends has been followed with the help of torque of kneaders in the reactor.
