摘　　要：在碾磨力场的作用下对聚丙烯酰胺(HPAM)接枝疏水单体苯乙烯(St),实现HPAM在固相力化学条件下的改性。通过正交试验,确定了固相力化学的最佳反应条件:St与HPAM的质量比为1:99,静压力为20kN,碾磨次数为20次,转速为40r/min。采用胶束增溶紫外分光光度法测试产物中St含量,结果表明:接枝产物中St的含量随着单体St加量的增加先增加后减小,静压力小于20kN时增加,大于20kN时下降;碾磨次数低于20次时增加,大于20次时几乎不变;转速在20～40r/min时基本不变,高于40r/min时,含量下降。To implement the PAM modifying with solid phase mechanochemistry,the PAM was grafted for hydrophobical monomer styrene under milling force.Through orthogonal experiment,the best conditions of solid phase mechanochemistry were determined: static pressure was 20kN,grinding was 20 times,rotation 40r/min,the proportion of St and HPAM was 1∶99.Ultraviolet spectrophotometer was used for testing the content of styrene in reaction.The result shows that with the increase of styrene monomer,the content of styrene in reaction increases first and then decreases.When the static pressure is less than 20kN,the content of styrene in reaction becomes more;the pressure is more than 20kN,the result is on the contrary.When the grinding is less than 20 times,the content of styrene in reaction becomes more;the grinding is more than 20 times,the content is nearly unchanged.When the rotation is between 20～40r/min,the content is also nearly unchanged;when it is more than 40r/min,the content is declined.
