| Zusammenfassung: | A polymer/organoclay composition having improved color stability. The composition includes a halogenated polymer matrix. It also includes an organoclay composition which is comprised of phyllosilicate clay and one or more quaternary ammonium compounds. The quaternary ammonium compounds include tri- and tetra- [poly]oxyalkylene quaternary ammonium compounds, the ether and ester derivatives thereof. The phyllosilicate clay phyllosilicate clay includes a smectite clay and the polymer includes polyvinyl chloride. The polymer/organoclay composition includes quaternary ammonium compounds selected from the following: tris[2-hydroxyethyl] tallow alkyl ammonium ion, tris[2-hydroxyethyl] hydrogenated tallow alkyl ammonium ion and tris[2-hydroxyethyl] stearyl alkyl ammonium ion. |
