Chapter 14, Problem 14.09 Multistep For a linear polymer molecule, the total chain length L depends on the bond length between chain atoms d, the total number of bonds in the molecule N, and the angle between adjacent backbone chain atoms , as follows: L = Nd sin ( ) (14.11) Furthermore, the average end-to-end distance for a series of polymer molecules r in Figure 14.6 is equal to r= =dVN (14.12) A linear poly(vinyl chloride) has a number-average molecular weight of 400000 g/mol; compute average values of L and r for this material. Part 1 x Carefully review Section 14.5 and the mer units in Table 14.3. Did you remember to multiply the number of atoms in the mer by its individual atomic weight? Did you total them correctly? If you are having difficulty with this problem, you may wish to review: Solving Equations Graphing Overview Calculate the repeat unit molecular weight of poly(vinyl chloride) in g/mol.
