Problem 4: Molecular Weight Distributions 5 points - As the lead polymer engineer at Eastman Chemicals Inc, you are charged with designing PET polymer blends to achieve desired toughness properties. You have access to two batches of monodisperse PET polymers (PDI = 1) with the properties shown in table 2. Table 2: PET Batch Properties Batch Number Average Molecular Weight (Mn) (g/mol) 5,000 35,000 A B 4.1 For your first blend, you mix 0.1 mole of batch A and 0.01 mole of batch B. What are the number and weight average molecular weights of the mixture? What are the number and weight average degrees of polymerization for the mixture? What is the PDI of your blend? 4.2 For your second blend, you mix 10g of batch A and 100g of batch B. What are the number and weight average molecular weights of the mixture? What are the number and weight average degrees of polymerization for the mixture? What is the PDI of your blend
