FIELD: chemistry.

SUBSTANCE: invention relates to the polymer composite moisture-retaining material, which can be used in the growing of modern technologies for intensive farming and for greening of urban and industrial landscapes and erosion protection of the surface. The composite moisture-retaining material is based on an acrylic copolymer and a filler. The acrylic copolymer is based on acrylamide and acrylic acid salts at a ratio of 25/75-75/25 mol % in the presence of a N,N'-methylene-bis-acrylamide crosslinking agent and a polymerization initiator. As a filler, a mechanically activated peat filler is used, which is a fine dried peat (the grinding degree is less than 0.3 mm) in an amount up to 65 wt % of the number of monomers based on the dry weight. A method for producing a polymer composite moisture-retaining material is described.

EFFECT: using the filler with a virtually unlimited source of raw materials, reduced cost of the water-retaining material, additional source of nourishment for plants, while maintaining the water-sorption properties on the level of existing filled and unfilled counterparts.
