【摘要】 本文研究了在硫氰酸钠浓水溶液中,丙烯腈（AN）与甲基烯丙基磺酸钠（SMAS）在pH5时的共聚合。在70℃下测得AN和SMAS的单体竞聚率r₁=0.54,r₂=0.13。据此计算了SMAS的Price Q和e值,分别为0.16和-0.43。AN和SMAS共聚反应的速度随SMAS含量增加而下降。更多还原

【Abstract】 The copolymerization of acrylonitrile （AN） with sodium methallyl sulfonate （SMAS） in concentrated aqueous solution of sodium thiocyanate at pH 5 has been investigated. Monomer reactivity ratios at 70℃ for AN and SMAS were found to be r₁=0.54, r₂ = 0.13. From these data Price Q and e values for SMAS were calculated to be 0.16 and -0.43 respectively. The rate of copolymerization of AN and SMAS decreased with increasing SMAS content.更多还原
