Abstract : In this work processes of grafted and block polymerization of polyacrylonitrile (PAN) and polyvinylidene chloride (PVDKh) in amorphous films of atactic polymethyl methacrylate (PMMA), oriented by extract, are studied. The selected polymers possess the combination of the properties, necessary for checking the assumptions presented. Oriented PMMA has heterogenic fibrillar structure (as crystalline materials) and is readily soluble in AN and VDKh. PVDKh in the process grafting is crystallized and it reproduces well the oriented structures of the materials of any nature, PAN - is cross-linked during the heating, both more heat and temperature-resistant, than PMMA, and they are not dissolved in the monomers.
