<p>The copolymer dispersions vinylchloride - acrylates are produced based on that principle, the substances increasing the critical concentrations of fillings in the dispersions are added to the polymerisation environment. The above mentioned substances are represented by polyvinyl alcohol and polyacrylates of alkaline metals in ammonium in the quantity of 0,2 up to 1,1 weight percent counted related to the total amount of used monomers and the value of critical filling concentration is increased to the value of 4,5 up 8,0 CaCO3/g closed to non volatile parts in the co-polymer dispersion, as a result of that.</p> |
