Using content from your lecture notes only, answer the following:

(a) Describe the general mechanical properties that you would expect to see in an amorphous thermoplastic polymer compared to semi-crystalline or crystalline polymers (i.e. what mechanical properties will be different between the two groups, and how will they be different?). Cover a range of different mechanical properties that we have discussed in class.

(b) Describe the types of bonding and types of structures that are generally present in these materials.

(c) For each of the properties you discusse above,  discuss the mechanisms of ductility. In your answer explain how the property is controlled at the atomic-scale and/or micro-scale.
