摘　　要：采用可控流变法制备高熔体流动速率(MFR)的聚丁烯-1(PB)/过氧化物母粒共混物,考察了PB/过氧化物母粒共混物的MFR、相对分子质量、熔点和力学性能。结果表明:与PB相比,PB/过氧化物母粒共混物的MFR增大,其相对分子质量、熔点和力学性能降低。过氧化物母粒的质量分数为2.5%时,PB/过氧化物母粒共混物的MFR为347.85 g/10 min,Ⅰ晶型熔点为122.71℃,Ⅱ晶型熔点为107.80℃。The high melt flow rate(MFR)polybutene-1(PB)/peroxide master batch blend was prepared by controlled rheological method.MFR,the relative molecular mass,melting point and mechanical properties of PB/peroxide master batch blend were investigated.The results show that compared with PB,MFR of PB/peroxide master batch blend increases,while its relative molecular mass,melting point,and mechanical properties decrease.When the mass fraction of the peroxide master batch is 2.5%,MFR of PB/peroxide master batch blend is 347.85 g/10 min,the I crystal melting point is 122.71℃,and the II crystal melting point is 107.80℃.
