Document Summary

The second mid-term will cover all the materials from part 1 and part 2 of the lecture notes, with focus on the latter. Part 2 of the notes corresponds to chapters 8 and 10 of. Essentials of polymer science and engineering by p. c. painter and m. m. coleman. Estimate the potential energy barrier of rotation for various bonds; Explain the principle of the random walk/flight and its application to. Calculate the root-mean-square end-to-end distance of polymer chains; Explain what the radius of gyration is and calculate it; Determine the minimal molecular weight at which a molecule starts exhibiting. Describe the various physical states of polymers and why the boiling point of polymers cannot be measured; Explain why tm is a first-order transition while tg is a second-order transition, Know what thermal transitions amorphous, semi-crystalline and crystalline. Explain the difference between the fringed micelle model and the folded-chain. Describe what spherulites are and when they are obtained;
