【摘要】 以间歇水相沉淀聚合方法对AN/VAc/SSS三元共聚进行了研究,确定了合适的聚合工艺条件,可以得到粘均相对分子质量在5.0×10~4～7.5×10~4的聚合物.改变AN/VAc/SSS的比例可以制得不同染色饱和值的高聚物,当高聚物中VAc含量在9%左右,SSS含量在0.35%时,所得腈纶的染色饱和值达到了3.0%.更多还原

【Abstract】 The water - precipitation copolymerization of AN/VAc/SSS using redox initiator system is investigated. The effect of different experiment conditions such as polymerization temperature, time, ratio of NaClO3/Na2 82(1)5 and monomer concentration are discussed. The polymers with different dyeabih’ty can be obtained by changing the ratio of AN/VAc/SSS.更多还原
