摘要：运用Ubbelohde式粘度计测定PBO/MSA溶液的粘度,采用稀释外推法对溶液浓度和粘度的关系进行了分析,结果发现当溶液浓度不太低时,PBO高分子链在溶液中存在聚集现象;当溶液浓度极低时,PBO/MSA溶液粘度随着浓度的降低而急剧增大,呈现"聚电解质效应";同时研究了PBO的重均分子量与特性粘数的关系,结果显示用半刚性聚电解质链模型来关联两者关系比刚性棒状模型更合适。
The property of PBO/MSA solution was studied by using Ubbelohde viscometer.The effect of the solution consentration on the viscosity was analyzed by diluted extrapolation method.The results showed that the PBO chain conglomerate in the solution with low concentration.And there is a 'polyelectrolyte effect' in PBO/MSA solution with an infinite diluted concentration.The effect of the [η] of PBO on its molecular weight was also investigated.The results revealed that the third-order polynomial based on the semi...
