Answer 1

Answer:

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.
