Abstract
The present invention discloses processes for forming polythiol compositions from olefinic hydrocarbons such as cyclooctadiene, cyclododecatriene, and trivinylcyclohexane. The polythiol compositions produced from these processes, including the sulfur-containing compounds of these compositions, also are described.
Claims21
A process for forming a polythiol composition, the process comprising:
- 1) contacting
- a) a hydrocarbon compound having at least two olefinic double bonds;
- b) H2S;
- and
- c) a phosphite compound;
- and
- 2) forming the polythiol composition;
- wherein a molar ratio of H2S to olefinic double bonds of the hydrocarbon compound is in a range from 10:1 to 500:1.
