15.16—How polyesters, such as terylene, are formed by condensation polymerisation reactions

Understand how polyesters, such as terylene, are formed by condensation polymerisation reactions.

Use —how polyesters, such as terylene, are formed by condensation polymerisation reactions to connect the rule to the data and decision in the question.

This matters because —how polyesters, such as terylene, are formed by condensation polymerisation reactions determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —how polyesters, such as terylene, are formed by condensation polymerisation reactions to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —How polyesters, such as terylene, are formed by condensation polymerisation reactions is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
