Below are 3 polymers to be examined for use as vascular graft materials. a. Which two do you believe would exhibit the highest and the lowest degrees of crystallinity, respectively, and why (10 points). b. What analytical technique would you use to determine the crystallinity of each material ( 5 points)? c. Assume the values below represent the Tg and Tm for each of the three materials. Based on this information, which of these would you select for this application and why ( 10 points)? (I) (II) (III)
