Abstract
ABSTRACTHomo‐ and copolymerization of 1‐hexene (H) and 1,7‐octadiene (O) were done using two different catalysts 1,4‐bis(2,6‐diisopropylphenyl)acenaphthenediiminedibromo nickel (II) andrac‐ethylenebis(indenyl)zirconium dichloride [rac‐Et(Ind)2ZrCl2]. The metallocene catalyst showed higher activity than the nickelα‐diimine catalyst in homo‐ and copolymerization. The1H NMR studies confirmed the formation of copolymers containing 8–47% of 1,7‐octadiene. In the copolymerization of hexene and diene, as the amount of incorporated diene in the copolymers increased, theirTgincreased. TGA results showed that thermal stability of the polymer increases with the increase of 1‐hexene incorporation in the polymer chain. Finally 1‐hexene/1,7‐octadiene copolymers were functionalized by triethoxysilane in the presence of hexachloroplatinic acid. The1H NMR spectrum of the functionalized samples showed that the double bonds in the copolymer structure were completely eliminated. The DSC analysis showed higherTgs for the functionalized copolymer. © 2020 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2020,137, 48934.
