The phase structures of PP-LDPE blends in isotropic and oriented states were studied by the methods of DSC and polarization IR spectroscopy. The composition intervals were established that correspond to the formation of interpenetrating network structures. The presence of LDPE increases the degree of PP orientation and the mechanical strength of the blends. This indicates that LDPE acts as a structure-modifying agent, while PP plays the role of strengthening (reinforcing) filler. A relationship between the deformation and strength properties of the oriented films of the PP-LDPE blend and the phase structure of the PP component is demonstrated. The stability of the blend to oxidation in the ozone-oxygen medium is determined by the structure of a less stable system component (PP). The oxidation rate reaches maximum in samples with an isotropic PP structure and is minimum in the blends with highly oriented PP component. |
