Important Equations from Polymers

1. Degree of Polymerization (DP): DP = \dfrac{\text{Molecular mass of monomer}}{\text{Molecular mass of polymer}}

2. Number Average Molecular Weight $(\bar{M_n})$: $\overline{M_n} = \dfrac{\sum (n_i \times M_i)}{\sum n_i}$

3. Weight Average Molecular Weight $(\bar{M_w})$: $\overline{M_w} = \dfrac{\sum (w_i \times M_i)}{\sum w_i}$

4. Polydispersity Index (PDI): $PDI = \dfrac{\overline{M_w}}{\overline{M_n}}$

5. Copolymer Composition:

• Mole fraction of monomer 1 $= \dfrac{n_1}{n_1 + n_2}$

• Mole fraction of monomer 2 $= \dfrac{n_2}{n_1 + n_2}$

6. Glass Transition Temperature (Tg): The temperature at which an amorphous polymer transitions from a hard and brittle state to a rubbery state.

7. Melting Temperature (Tm): The temperature at which a crystalline polymer undergoes a transition from a solid to a liquid state.

8. Markovnikov's Rule for Polymerization: In the addition polymerization of unsymmetrical monomers, the positively charged unit of the growing chain gets the new monomer unit.
