Abstract
Urethane thermoplastic elastomers were synthesized from oligobutylene glycol adipate and diisocyanate using the aromatic diol 2,2′-[propane-2,2-diylbis(p-phenyleneoxy)]diethanol as a chain extender. 4,4′-Diphenylmethane diisocyanate and isophorone diisocyanate were used as diisocyanates. The synthesis of a thermoplastic elastomer based on cycloaliphatic diisocyanate was carried out in the presence of an organotin catalyst. It was found that replacing the aromatic diisocyanate with a cycloaliphatic one led to the transition of the amorphous polymer into a crystalline one. At the same time, its deformation and strength properties, hardness, and light resistance increased.
期刊介绍：
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
