Sequence the process of polymerization

write a note on 2 Dimensional Defects(All of them), Electron Microscope(TEM, SEM, STM) support your writing with pictures

Use Graphical representation to show how crystal growth rate depends on crystallization temperature. Label Tm and Tg on the x axis and label the region where you will find large crystals to nucleate and grow

C. 1.74 L/min d. 0.87 L/min e. 0.44 L/min f. 0.21 L/min 8. A 0.5 mol/L glyceride-ester solution in MeOH is fed at 0.07 L/s into a 250 L CSTR in the pilot plant. The catalyst is charged in a separate stream at 0.03 L/s. The generic reaction rate is independent of the concentration of MeOH and can be described by: (-REster) kcat CEster mol/L.S Product stream analysis shows that 37% of the glyceride-ester has reacted. For this system the rate constant kcat is: W a. 2.35E-4 (1/min) b. 0.014 (1/min) V C. 0.019 (1/min) d. 0.027 (1/min) e. 0.055 (1/min) f. 1.1 (1/min)

8. draw a diagram of the simple distillation system used to purify chloride and label each piece

Which of the following processing methods would you use for compounding a polymer with colorants and stabilizers a) injection moulding b) thermoforming c) single-screw extrusion d) twin-screw extrusion e) transfer moulding.
