Abstract:
      The crystalline behavior, processing performance of two different trans-1,4-poly(butadiene-co-isoprene) copolymer rubbers (TBIR) and properties of sidewall stock of PCR tire utilized with TBIR were studied. It was found that, compared with trans-1,4-polyisoprene (TPI), TBIR showed a weaker crystallization performance and a lower glass-transition temperature (Tg). Compared with nature rubber (NR) and cis-1,4-polybutadiene rubber (BR), TBIR presented improved processing properties. Compared with NR, BR and TPI, TBIR demonstrated excellent hot oxygen ageing resistance. Compared with NR/BR and NR/BR/TPI vulcanizates, NR/BR/TBIR(45/35/20) vulcanizates showed excellent physical and mechanical properties, lower heat built-up and outstanding crack-growth resistance. So TBIR was a novel synthesis rubber for high performance tire sidewall.
