Poly $($propylene fumarate$)($PPF$)$ is copolymerized with different fraction $(\backslash$Phi $)$ of poly$($caprolactone$)$

diacrylates $($PCLDAs$)$ of three different molecular weights $($MW: $530,1250$ and $2000)$ by

polymerizing the double bonds.

A$)$ Comment on the relative crystalline$/$amorphous behavior pure PPF$,$ pure PCLDA $($of

three different MWs$)$ and their copolymers $($show the trends clearly$).$ Provide an

explanation.

B$)$ The tensile modulus of the copolymers is shown below. Provide an explanation for this

response in terms of materials character.
