FIELD: chemistry.
SUBSTANCE: polyacrylic (co)polymer which is curable under the effect of atmospheric moisture and having elastometic properties is a plurality of acrylic prepolymer segments interlinked by urea or urethane links caused by moisture curing. Each of the plurality of prepolymer segments is a homopolymer or a copolymer of methylmethacrylate, C1-C16-alkylacrylate and C1-C16-alkylmethacrylate as the predominant monomer group. The moisture-curing method involves formation of a plurality of segments of an acrylic prepolymer, obtaining isocyanate-functionalised segments of the acrylic prepolymer, storing the isocyanate-functionalised segments in anhydrous state, followed by deposition thereof onto a substrate and moisture-curing to form a polyacrylic polymer.
EFFECT: obtaining polyacrylic (co)polymers cured under the effect of atmospheric moisture and having elastomeric properties, which retain resistance to UV rays, optical transparency, wear and physical properties of conventional thermoplastic acrylic polymers.
