不良溶剂

特别对于不良溶剂情况，在高接枝度时大多数反离子聚集在界面附近。

Especially in the poor solvent case , most of counterions gather near the interface at high grafting densities .

微球收率随架桥剂用量减少，良溶剂用量增加而增加；并且受到不良溶剂中乳化剂种类的影响。

The recovery of the microspheres is increased with decreasing the bridging liquid and increasing the good solvent and poor solvent .

我们的结论是对聚合物来说，越是不良溶剂，则GPC普适标定的适用性越小。

Our conclusion is that the poorer the solvent for the polymer , the smaller the suitability of the GPC universal calibration .

AS溶解在相对不良溶剂，其在TATB表面上的被吸附量大于相对良溶剂中的。

AS can be more easily adsorbed at the surface of TATB in non-solvent than in good solvents .

与单体/聚合物不溶体系的悬浮态乳液聚合相比，对于MMA悬浮态乳液聚合，需要加入聚合物的不良溶剂，如环己烷，才能得到疏松、多孔结构的聚甲基丙烯酸甲酯（PMMA）树脂。

Comparing with the suspended emulsion polymerization of monomer / polymer dissoluble system ( such as vinyl chloride ), non-solvent of PMMA , such as cyclohexane , must be added to the polymerization system , to obtain porous PMMA resin .

在甲苯-C60体系中通过缓慢滴加不良溶剂的方法制备了具有树枝状和花簇状的C60纳微米结构。8.本课题组首次用富勒烯C60/C70混合物制备出C60/C70纳米纤维。

The flower cluster and dendritic-like structure of C60 micro / nanometer structures was prepared by slowly dropping in toluene-C60 system . ( 8 ) The C60 / C70 nanofibers were synthesized with a mixture of fullerenes C60 / C70 powders .

歌剧中的穷途末路Florg-Huggins法不宜用于聚合物与不良溶剂形成的体系。

The Flory-Huggins method is unsuitable to those polymer solutions which consist of polymer and poor solvents .

而对其不良溶剂如正己烷、甲苯几乎不响应。

But the response of the resistors to the poor solvent of PEG such as n-hexane and toluene , is hardly observed .

而经不良溶剂处理后，接枝链卷曲成团，形成孤立的球状结构。

In good solvent , grafted chains stretched to form flake structure , while in poor solvent they curled to form round configuration .

由无定形聚苯乙烯不良溶剂（如庚烷、异辛烷等）配制的悬浮液，固含量小于15%时，体系呈现牛顿流体性质。

However , when the suspension is prepared by a non-solvent for amorphous polystyrene , such as heptane and isooctane , and the sPS content is lower than 15 % , the fluid is Newtonian .
