Abstract

RAFT polymerization was applied for the synthesis of poly(4-vinylpyridine) and copolymers of 4‑vinylpyridine, containing 5 or 10 mol % of hydrophobic monomers of methyl methacrylate or methyl acrylate. The influence of chemical nature of hydrophobic comonomer and the copolymer composition on physico-chemical properties of polymers and their ability to strengthen sandy soils was systematically studied. It is shown that introduction of MMA or MA units does not affect the glass transition temperature of P4VP, its dispersibility in aqueous media and has minor effects on wettability of polymer films. At the same time, surface activity of P4VP was increased, especially for the samples, containing 10 mol % of comonomer units. P4VP itself as well as its copolymers demonstrate good mechanical and structural stabilizing properties towards sandy soils, if the sand was soak by polymer aqueous dispersions at pH 3. The sand, stabilized by the copolymer from 90% of 4VP units and 10% of MA units, demonstrated the best mechanical strength and durability towards both dynamic and static perturbations.
