FIELD: building materials.
SUBSTANCE: group of inventions relates to a method for the production of a drywall additive, an additive prepared by this method, and a composition for drywall formation, including it. The method for the production of a drywall additive includes obtainment of a composition based on polystyrene sulfate (SPS) represented by a given chemical formula, by means of a sulfonation reaction with polystyrene and sulfuric acid. The composition for formation of drywall containing an outer sheet and a gypsum core includes gypsum, hardener, weight reduction substance, and water in a composition of the specified drywall additive.
EFFECT: improvement of porosity of a foam drywall component, additive fluidity, and setting time.
