Answer to Question 1

Modulus will likely be reduced because the toughness modifiers will have longer elongations than will the base polymer and will therefore decrease stiffness

Answer to Question 2

Crosslinks tie the molecular chains together and make long-range movements more difficult. Therefore, as the amount of crosslinking increases, the glass transition temperature should also increase.
