But it was difficulted to decolorize the basic dye cationic yellow.

In the wash solution, these positively charged cationics adsorb to the negatively charged surface of fabrics.

The preparation and application of internal and external sulfonium cationic polymer since 1960s are summarized comprehensively in this paper.

Human defensins,found in the blood,intestinal tract and epithelial cells,are small,cystin-rich cationic peptides with special structure.

This paper optimized the hyperhaline/cationic polymer drilling fluid for deepwater drilling by a lot of experiments.

A process for decolourization of anionic dye containing wastewater by using waste plastics in the presence of cationic auxiliary and sodium dodecylbenzene sulfonate has been studied.

This amphipathic nature holds whether the detergents are anionic, cationic, or nonionic.All types are illustrated in the figure.

As a quaternary cationics,amine cake has such properties as wetting,adsorption and emulsification,and brings a good effect by oil coating compound fertilizer when it is added into oil.

The cationic ring-opening polymerizations of epoxide based monomers were studied using tris(2-hydrooxyethyl) isocyanurate(THEIC) as initiator and trifluoroboron plus ether complex system as catalyst.

Polytetrahydrofuran(PTHF) with narrow molecular mass distribution was prepared by cationic ring-opening polymerization of tetrahydrofuran using H_2SO_4·SO_3-HClO_4 system as a catalyst.
