摘要
以阴离子活性聚合法合成了分子量窄分布的聚苯乙烯,并通过粘度测量、GPC 测量和光散射测量确定了线型聚苯乙烯于25℃甲苯中的 Mark-Houwink 方程[η]=8.41×10^(-3)×M^(0.74)。
A series of polystyrene with different mole-cular weights and narrow molecular weight dis-tribution have been synthesized by anionic livingpolymerization.The Mark-Houwink equation[η]=K_η·M^(a)=8.41·10^(-3)·M^(0.74)was established for lin-ear polystyrene at 25℃ in toluene by viscometry,GPC and light scattering.
