FIELD: chemistry.
SUBSTANCE: invention relates to chlorionated thermoplastic materials with mineral filler, having compatibility between said filler and chlorinated thermoplastic resin. The mineral filler compatibility agent in form of calcium when producing chlorinated thermoplastic material contains a comb-shaped polymer which contains at least one polyalkylene oxide group which is grafted onto at least one ethylenically unsaturated anionic monomer. The comb-shaped polymer contains at least one anionic monomer with ethylenic unsaturation and a monocarboxyl or phosphoric group or mixtures thereof, at least one non-ionic monomer containing at least one monomer of formula (I): 
, where m and p denote the number of alkylene oxide groups, which is less than or equal to 150, n denotes the number of ethylene oxide groups, which is less than or equal to 150, q denotes a whole number equal to or less than 1, where 5≤(m+n+p)q≤150, R1 denotes hydrogen or a methyl or ethyl radical, R2 denotes hydrogen or a methyl or ethyl radical, R denotes a radical which contains an unsaturated polymerisable group, preferably associated with a group of vinyl compounds, or a group of acrylic, methacrylic, maleic esters, or a group of allyl or vinyl ethers, which are substituted or unsubstituted, R' denotes hydrogen or a hydrocarbon radical with 1-40 carbon atoms or a ionic or ionisable group, such as carboxyl, and preferably denotes a hydrocarbon radical with 1-12 carbon atoms. The invention also relates to chlorinated thermoplastic materials containing at least one chlorinated thermoplastic resin, calcium carbonate and at least one compatibility agent.
EFFECT: high impact strength.
