PHOSPHITE REACTIONS IN THE PRESENCE OF METAL SOAPS FOR LIQUID STABILISERS |
摘要 |
<p>The present invention pertains to a process for the preparation of a liquid stabilizer for imparting heat stability to polyvinyl chloride compositions which is essentially solvent-free, comprising the steps of reacting one or more carboxylic acids with one or more metal sources in the presence of one or more organophospite ester-reactive solvents while stripping off water, wherein the metal in said metal source is selected from the group consisting of Ca, Ba, Zn, Sr, K, and Cd; adding one or more organophosphite esters selected from the group consisting of triorganic phosphites, organic acid phosphites, diphosphites, and polyphosphites, and reacting the one or more organophosphite ester-reactive solvents with said organophosphite esters, while distilling off phenol; and, optionally, adding one or more additives known in the art before, during, or after the addition of the one or more organophosphite esters to the reaction mixture.</p> |
