PECULIARITIES OF THE STRUCTURE OF SOME PO LYDIENES AND POLYOLEFINS PREPARED WITH SUPPORTED METAL-COMPLEX CATALYSTS

The structure, phase composition, and temperature-mediated behavior of polybutadienes prepared with binuclear metal complex systems immobili zed on a solid support were studied. It was found that polybutadienes of nascent structure are a mixture of trans-1,4- and cis-1,4-homopolym ers, whereas 1,2-units are randomly distributed in macromolecules of t rans-1,4-polybutadiene. It was shown that, in principle, the nascent t rans-1,4-polybutadiene exhibits a three-phase structure and contains c rystalline and amorphous phases and a low-temperature form of the meso morphic phase component.
