Comparison of structure and properties between self-made trans-1, 4-polyisoprene and similar foreign product

The comparison between self-made trans-1, 4-polyisoprene (TPI) and similar foreign product were conducted in trans-unit content, crystallinity, relative molecular mass. The elemental analysis of ash of foreign crude TPI was conducted, and its catalyst system was presumed. The results showed that com...

Zusammenfassung:The comparison between self-made trans-1, 4-polyisoprene (TPI) and similar foreign product were conducted in trans-unit content, crystallinity, relative molecular mass. The elemental analysis of ash of foreign crude TPI was conducted, and its catalyst system was presumed. The results showed that compared with foreign TPI, the self-made TPI had higher trans-unit content and crystallinity, lower Mooney viscosity, narrower relative molecular mass distribution, and better mechanical properties. The catalyst systems used for synthesis of TPI were similar.
