- Аннотация: The behavior of acrylic acid–4-vinylpyridine copolymers of different architectures, namely, with gradient and block distributions of comonomer units in a chain as well as with quaternized 4-vinylpyridine units, is studied. It is shown that all the copolymers are prone to aggregation in acidic and alkaline media and that the sizes of aggregates and the regions of their stability are determined by chain microstructure. The aggregates formed in acidic media exhibit temperature sensitivity. The kinetics and mechanism of copolymer adsorption from solutions on the surface of nylon membranes are explored. It is shown that the block distribution of units substantially increases the adsorption efficiency, while the quaternization of 4-vinylpyridine units decreases the monolayer adsorption parameters.
