Question

For the polymer listed, given the mass range in (g/mol) and Ni (number fraction) and wi(weight fraction).

Compute the number - average molecular weight for the polymer.

Calculate the weight - average molecular weight for the polymer

The degree of polymerization of for the polymer listed.

Molecular Weight Data Table for = Poly (vinyl chloride) (PVC)

- = Molecular Wt(g/mol)|----xi--- |-- wi

- = 8,000 - 16,000 -------|-- 0.06 --|-- 0.02

- = 16,000 - 24,000 ------|--0.14 --|-- 0.1

- = 24,000 - 32,000 ------|--0.24 --|-- 0.19

- = 32,000 - 40,000 ------|--0.31 --|-- 0.31

- = 40,000 - 48,000 ------|--0.19 --|-- 0.26

- = 48,000 - 56,000 ------|--0.06 --|-- 0.12
