You have been given the modulus thermograms for three polymers shown below. Two of the traces belong to crosslinked polymers and one trace to an un-crosslinked polymer. A Modulus B Temperature 1.1 In the modulus thermograms above, please label the glassy, rubbery, and viscous regimes as appropriate for each polymer. 1.2 Circle the glass transition temperatures in each trace. 1.3 Which trace belongs to the un-crosslinked polymer? How do you know? 1.4 Which trace belongs to the highly crosslinked polymer? How do you know? 1.5 Which trace belongs to the lightly crosslinked polymer? How do you know
