V v- 2. Assume the simple approximation for the temperture-dependence of the excluded volume: = (1-4). Consider a polymer chain with N = 1000 Kuhn monomers, with a Kuhn length of b = 3 in a solvent with a 6-temperature of 0 = 30 C. 63 (i) What would the chain size be at temperatures of T = 10, 30, and 60 C? (ii) Sketch the temperature dependence of the size of this polymer. (iii) What is the degree of polymerization of the largest chain that stays ideal at T = 60 C? (Hint: think thermal blob). (iv) Estimate the degree of polymerization of the largest chain that dissolves in the solvent at T = 10 C
