Answer to Question 1

Styrene is both a solvent and a participating component in the crosslinking. As a solvent it assists in facilitating the reaction by adding mobility to the polymers. As a participating component in the crosslinking it bridges between polyester molecules making the crosslinks easier to form.

Answer to Question 2

These are thermoset resins which have been polymerized but not crosslinked. The resins are B-staged to improve the handling and control the cure.
