19. Write down the equation describing the mole fraction of x-mer (x₁) present in a polycondensation reaction at an extent of reaction p. 20. Copolymerization equations are expressed as follows: d[M₁] [M₁] (k₁[M]+ k₂1[M₂]] rifi²+fif₂ = F₁ = d[M₂] [M₂] k12[M₁] + K22[M₂] rifi² + 2f₁f2 + 12f2² A. What is the steady state assumption used in deriving the copolymerization equation? B. For the azeotropic copolymerization, obtain an equation relating monomer feed ratio (fa) with reactivity ratios (rå and râ).
