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.
Claims22
A polythiol composition derived from cyclododecatriene comprising sulfur-containing compounds, the sulfur-containing compounds of the polythiol composition comprising:
- i) an average of at least 20 wt. % thiol sulfur;
- and
- ii) an average of from 0.1 to 8 wt. % sulfide sulfur.
Dependencies are inferred from the claim text.
