Important Equations from Polymers

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


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


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


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


  1. Copolymer Composition:

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

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


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


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


  1. 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.
