摘　　要：研究了不同门尼粘度的反式-1,4-聚异戊二烯(TPI)与氯丁橡胶(CR)并用胶的性能,并对比了CR/TPI与CR硫化胶的性能。结果表明,CR中并用10份TPI可明显改善开炼机混炼时的粘辊性、胶料在硫化过程中产生气泡等缺陷;并用TPI后,硫化胶的物理机械性能、耐热老化性能和耐臭氧性能有所下降,但当TPI与CR门尼粘度相近时,硫化胶的耐屈挠疲劳性能可提高1倍左右。The blend properties of ehloroprene rubber （CR） and trans -- 1,4 -- polyisoprene （TPI） with different mooney viscosity were studied, and the vulcanizate properties of CR/TPI and CR were compared. The results showed that the roll sticking property of CR was significantly improved, and did not produce bubble during the curing process by adding 10 phr TPI; Blended with TPI, the physical- mechanical properties, thermal aging resistance and ozone resistance of CR vulcanizate all dropped, The flex durability was increased by 1 time when the mooney viscosity of CR and TPI were equivalent.
