<p>Use of a comb polymer containing polyalkylene oxide group grafted on anionic monomer having ethylenic unsaturation, as a compatibilizing agent of a mineral filler, in a process for making a chlorinated thermoplastic material containing a mineral filler. An independent claim is included for a chlorinated thermoplastic material comprising a chlorinated thermoplastic resin, a mineral filler, a compatibility agent, optionally a thermal stabilizer, a UV stabilizer, a lubricant, rheology modifier, an impact modifier and/or a processability agent, optionally a compatibility agent other than the comb polymer, comprising a fatty acid containing 8-20 carbon atoms, preferably stearic acid and its salts or their mixtures, preferably as calcium salt.</p> |
