Molecular polymer–polymer compositions. Synthetic aspects

The main ways of improving the compatibility of polymer–polymer compositions containing polyolefins as one component are considered. Considerable attention is given to the preparation of polyolefins in the presence of an ingredient bound to the catalyst in the catalytic (including consecutive) polymerisation of olefins. The so-called reactor blends and the synthesis and structure of diblock and conducting composites are described. The important role of compatibilisation of polymers of different nature with the use of a third component is pointed out. The formation mechanism of molecular compositions, the structure and properties of the intermediate layer and the main fields of application of synthetic polyolefin–polymer compositions are discussed.
