Process for producing matte vinyl chloride polymers. |
摘要 |
<p>Matte vinyl chloride polymers are prepared by suspension polymerizing a vinyl chloride monomer or a vinyl monomer mixture mainly comprising vinyl chloride in an aqueous medium in the presence of (A) a polyfunctional monomer having at least two ethylenic double bonds in a molecule and (B) a polymeric matting agent containing 3 to 25% by weight of a tetrahydrofuran-insoluble gel fraction. The polymers are effectively moldable and present uniform matte effect.</p> |
