Description
Summary:The special features of the properties and structure of block copolymers based on PDMS and polyphenylsilsesquioxane crosslinked via the rigid phase have been studied by mechanical, dielectric, X-ray diffraction, electron microscope, and other methods. The properties of these block copolymers depend on the MM ratio of the flexible and rigid blocks. The strain mechanism and the nature of the changes in mechanical properties of crosslinked block copolymers on heating are discussed.
