$3\mathrm{.}2$ Assume you are exploring using materials as a porogen for a device made of high density

poly$($ethylene$)$ in order to improve anchorage in surrounding tissue. In this case, you

would plan to insert the porogen during fabrication of the device and then heat the device

to remove the porogen. You believe that low density poly$($ethylene$)$ may be an appropriate

choice, but your boss is not convinced.

a$.$ Using data in Table $3\mathrm{.}2,$ describe the potential concern of use of low density

poly$($ethylene$).$

b$.$ Of the characterization techniques discussed thus far in the book, which one would be

most appropriate to use to address your boss's concerns? To move forward with low

density poly$($ethylene$)$ as a viable option, describe the outcome of this test.
