| 产品介绍 |
一般描述：线性聚乙烯亚胺(L-PEI 2500)是一种高电荷的阳离子聚合物，容易结合高阴离子底物。工业上，线性PEI可以通过调节其性质和改善其对表面的粘附性来改善带负电染料的外观。 分子量: ~ 2500 熔点:75-90o Linear polyethylenimine (L-PEI 2500) is a high-charge cationic polymer that readily binds highly anionic substrates. Industrially, linear PEI can improve the appearance of negatively charged dyes by modulating their properties and improving their adherence to surfaces. |
