Improved methods of –PNS synthesis by adjusting basic parameters intended for obtaining naphthalene formaldehyde oligomers with optimal molar mass distribution. Resulting product is polymethylene naphthalenesulphonate –PNS–K4 (5–7, 6–6–polymethylene naphthalene – sodium sulphonate) with improved cement mortars plasticizing properties. Plasticizing effect: – PNS–K4, as an additive, is viewed in comparison to the known Kratasol plasticizer (produced by Superplast). By its plasticizing properties, effect on the strength and on the kinetics of concrete hardening, the analyzed PNS–K4 is not inferior to Krasatol performance and shows similar results.
