FIELD: chemical or physical processes; manufacturing technology.
SUBSTANCE: invention relates to a phthalate-free composition suitable for use as a plasticizer for acrylic mastics and adhesives. Described is a plasticizer composition for acrylic mastics and adhesives, comprising: a) at least one hydrocarbon-containing part of oil origin or obtained during conversion of biomass, and b) at least one copolymer resulting from copolymerization of: at least one monomer selected from acrylic acid and any of its salts, optionally at least one monomer selected from methacrylic acid and any salt thereof, at least one monomer, selected from monomers of formula (I) R - X - R' (I), according to which R is a polymerizable unsaturated functional group selected from acrylate, methacrylate, methacryl urethane, vinyl or allyl, R' denotes hydrogen or an alkyl group having 1 to 4 carbon atoms, X represents a structure comprising n links of ethylene oxide EO and m links of propylene oxide PO, m and n are two integers ranging from 0 to 150, at least one of which is not zero. Also disclosed are an acrylic adhesive composition, an acrylic adhesive composition and use of the composition.
EFFECT: improved compatibility between polymer matrix of acrylic mastic and adhesives with hydrocarbon-containing solvent.
