FIELD: CHEMISTRY. ^ SUBSTANCE: invention relates to copolymer, which is simultaneously a binder and a rheology modifier for aqueous suspensions of pigments an/or mineral filling substances, and is used to produce granules of pigments and/or mineral filling substances. Granules are recovered and formed from elementary particles with specific surface area determined according to Brunauer-Emmet-Teller method withing 0.5 m2/g to 200 m2/g range, as defined in ISO standart 9277, granules, easily re-dispersed in thermoplastic resins, which consist of monomer units ), b), ±) and d), sum of which is 100 percent by weight. The said invention relates to rheology modifier for aqueous suspension of pigmnets and/or mineral filling substances, which is also a binder, to viscosity-reducing agents for aqueous suspensions of pigments and/or mineral filling substances, which are also binders, to dispersing agent, which is also a binder, to application of the said copolymer, to granules of pigments and/or mineral filling substances, to application of the said granules and/or mineral filling substances in fields relating to fine powder use, to filled thermoplastic resin, to PVC-based resin and to polyolefin resin, obtained using the said granules and/or mineral filling substances, as well as to products made of such resin. Utilisation of the said copolymer provides for starting suspension viscosity control, when preparing agglomerated pigments and/or mineral filling substances, which can be easily re-dispersed in thermoplastic resins, PVC-based in particular. Recoverable granules of pigments and/or mineral filling substances obtained using the said copolymer are easily dispersable in plastic compositions, as well as in paint compositions. ^ EFFECT: lower cost of plastic and improved mechanical and temperature resistance thereof. ^ 36 cl, 7 ex, 1 tbl |
