Number average and weight average molecular weight are 2 common measures used to describe polymers. 1) Which measure is more indicative of rheological and mechanical properties and 2) please calculate Mn and Mw values for the sample listed in the table below. Number of Molecules Mass of each Molecule 1 1,100,000 3 750,000 5 700,000 8 650,000 10 603,000 13 525,000 20 500,000 13 450,000 10 400,000 8 350,000 5 300,000 3 275,000 1 195,000 3) List the steps involved in film formation of a latex. What are some properties of the polymer making up the latex that determine whether or not successful film will form? 4) Wetting of a surface with the coating material is required for it to spread appropriately and be able to adhere. Give a definition of wetting and a definition of adhesion. 2 / 2 121%
