| Popis: |
The branched chain structures of imported natural rubber RSS-1 and isoprene rubber molecular chains were compared and analyzed by nuclear magnetic resonance spectrometer. The results showed that the molar fraction of epoxy group in the branched chain structure of the RSS-1 molecular chain was 0.02%, the hydroxyl group was 0.16%, and the 3,4-isoprene unit was 0.20%. The branched chain structure of isoprene rubber molecular chain did not contain epoxy groups and hydroxyl groups, and the molar fraction of 3,4-isoprene units was 0.94%. |
