(a) Schematically illustrate a plot of spherulitic transformation rate as a function of crystallization temperature. Assume the Tmelt is 150C. Assume isothermal transformation at temperature of interest. (b) Can the response you drew be determined with one experiment? How was rate determined. Describe using schematics and text how the data presented in your response in part (a) was generated. c) Assuming the material in part (a) has the molecular weight of 25,000g/mol. On the same graph draw the spherulitic growth behavior of an identical composition polymer with a molecular weight of 15,000g/mol. Label the curve. Why did you draw it this way? (d) Schematically illustrate the microstructure of the 25,000g/mol polymer when transformed at 130C versus one transformed at approximately 50C. What is the physical mechanisms that drive the growth and nucleation in each of those cases
