Amides and Condensation Polymers (Polyamides and Polyesters)Sign up

understand that amides can be prepared from acyl chlorides · be able to describe: (i) condensation polymerisation for the formation of polyamides such as nylon and proteins; (ii) addition polymerisation, including poly(propenamide) and poly(ethenol) · be able to draw the structural formulae of the repeat units of the polymers in 19.8 · be able to comment on the physical properties of polyamides and the solubility in water of the addition polymer poly(ethenol) in terms of hydrogen bonding, including soluble laundry bags or liquid-detergent capsules (liquitabs)
