Another approach used for deactivating part of the amine groups of polyethylenimine was to use a partial quaternization of polyethylenimine with ethyl iodide. The membranes formed were similar in properties to those made by the partial polyethylenimine neutralization. Still another type of amine polymer was prepared by free radical polymerization of a mixture of diallylamine hydrochloride, dimethyl diallyl ammonium chloride and sulfur dioxide. This polymer in the free base form for interfacial reaction had reactive secondary amine groups and non-reactive quaternary amine groups ... 

Various combinations of synthetic polyelectrolytes are applied to the formation of polyelectrolyte shells onto colloid particles. Polyelectrolytes are divided into weak and strong ones. The examples of the first ones are sodium poly(styrene sulfonate) (PSS) and polyaniline propanesulfonic acid. Polyacrilic acid is an example of weak polyelectrolyte. Both examples are polyanions. Polyamines with various number of assistants at the atom of nitrogen are basically used as polycation components, for example poly(allylamine hydrochloride), polyethylenimin, etc.
