Answer 2

Here's a head-to-tail condensation I remember from my Grad School days; but after this, you'll have to entertain contributions from others...

Bis-Phthaloyl Chloride + Ethylene Glycol (typically in an aprotic solvent) => Polyphthaloylethylene Glycol Ester (a Polyester) + HCl

Cl-CO-(C6H4(ring))-CO-Cl + HOCH2CH2OH => ---HO-CH2CH2O-[-CO-(C6H4)-CO-OCH2CH2O-]-... + HCl

As I recall this is referred to as a nucleophilic condensation with HCl

As I recall this is referred to as a nucleophilic condensation with HCl as by-product.
