If 200 g of benzoyl peroxide are used with 38 Kg of PTFE monomer, calculate the expected molecular weight of the polymer if (i)
den301095 [7]

Explanation:

The molecular weight of benzoyl peroxide is 242.23 g/mol.

Therefore, number of moles present in 200 g of benzoyl peroxide are as follows.

            No. of moles = \frac{mass}{\text{molar mass}}

                                  = \frac{200 g}{242.23 g/mol}

                                  = 0.825 mol

Molecular weight of PTFE is 100 g/mol.Hence, calculate the number of moles of PTFE in 38 kg as follows.

As 1 kg = 1000 g. So, 38 kg = 38000 g.

             No. of moles = \frac{mass}{\text{molar mass}}

                                  = \frac{38000 g}{100 g/mol}

                                  = 380 mol

As it is given that the initiator is 15% active. So, actual number of moles of benzoyl peroxide are as follows.

                        0.15 \times 0.826

                           = 0.124 mol

For combination, 1 mol of benzoyl peroxide produces 1 chain. Therefore, degree of polymerization will be calculated as follows.

                    DP = \frac{380 mol}{0.124 mol}    

                          = 3065.33 mol

Average molecular weight of monomer is as follows.

       \frac{0.124}{0.124 + 380} \times MW_{benzoyl} + \frac{380}{0.124 + 380} \times MW_{PTFE}

       = 100.05 g/mol

Therefore, calculate the expected molecular weight of polymer as follows.

                   3065.33 \times 100.05 g/mol

                     = 306675.23 g/mol

Hence, for disproportion 1 mole benzoyl peroxide produces 2 chains.

                     DP = \frac{2 \times 380}{0.124}

                           = 6129.03

Therefore, calculate the expected polymer weight as follows.

                     6129.03 \times 100.05

                   = 613209.68 g/mol

Thus, we can conclude that the the expected polymer weight is 613209.68 g/mol.
