Abstract

The blend properties of chloroprene rubber(CR) and trans1,4-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.
