Hello
Stuck on two questions help needed.
Given that esterification is a reversible reaction, suggest how, in the formation of a polyester, the equilibrium can be disturbed so as to give almost complete conversion (rather than an equilibrium mixture). (4)
Contrast the behaviour of the polymer from 1 (Ch3cooh and Hoch2ch2oH) with that of poly(phenylethene) (polystyrene) in its resistance to attack by NaoH(aq). State the type of reaction that occurs and identify the reaction products.
Thanks

What methods of shifting equilibrium do you know?
I don't see how to produce a polymer from acetic acid and glycol. I guess I know what the question is about, but as stated it makes no sense to me.
