Abstract
The use of fatty oil ex Helianthus annuus containing 78 to 92% by weight oleic acid and 2 to 10% by weight linoleic acid for the production of alkali metal, ammonium and/or alkanolammonium salts of optionally dihydroxy-substituted fatty acids as emulsifiers for emulsion polymerization. Excellent polymerization results are obtained despite the high linoleic acid content.
Claims16
In a emulsion polymerization process, the improvement wherein the emulsifier comprises an emulsifying effective quantity of at least one salt of a fatty acid mixture wherein said salt is selected from the group consisting of alkali metal, ammonium, and alkanolammonium salts, and wherein the fatty acid mixture is obtained from a fatty oil ex Helianthus annuus wherein the fatty acid mixture comprises the following components:
- ______________________________________ oleic acid:
- 78 to 92% by weight linoleic acid:
- 2 to 10% by weight palmitic acid:
- 2 to 5% by weight stearic acid:
- 2 to 7% by weight, and up to 1% by weight of one or more of the following acids:
- myristic, palmitoleic, linoleic, arachic, eicosenoic, and erucic acid. ______________________________________
An emulsion polymerization reaction mixture which contains an emulsifying effective quantity of at least one salt of a fatty acid mixture wherein said salt is selected from the group consisting of alkali metal, ammonium, and alkanolammonium salts, and wherein the fatty acid mixture is obtained from a fatty oil ex Helianthus annuus wherein the fatty acid mixture comprises the following components:
- ______________________________________ oleic acid:
- 78 to 92% by weight linoleic acid:
- 2 to 10% by weight palmitic acid:
- 2 to 5% by weight stearic acid:
- 2 to 7% by weight, and ______________________________________
- up to 1% by weight of one or more of the following acids:
- myristic, palmitoleic, linoleic, arachic, eicosenoic, and erucic acid.
