Question: Using the basis set in Example 4.10 and the group-contribution methods in Table 4.6, find the polymer repeat unit that has a glass-transition temperature of

Using the basis set in Example 4.10 and the group-contribution methods in Table 4.6, find the polymer repeat unit that has a glass-transition temperature of $383 \mathrm{~K}$, density \(\cong1.5

\mathrm{~g} / \mathrm{cm}^{3}\), and water absorptivity $\cong0.005\mathrm{~g}$ water/g polymer.

Data From Example 4.10:-

Estimate the glass-transition temperature for the polymer repeat unit [-(CH2CH2CHCI)].

Table 4.6:-
