Answer 2

Answer:

Explanation:

The compound used as a reactive diluent in unsaturated polyester resins is Styrene.

• In polyester resins, styrene is used as a solvent until cross-linking takes place when it becomes an integral part of the thermoset.
• In the resin, if there is the availability of any unused styrene it will be released into the atmosphere in the gaseous state.
• Emissions of styrene into the environment produce a noticeable odor. When the emission crosses certain levels, it can produce a narcotic effect.
