Polyesters and Polyamides

suggest a reason why the melting point for nomex is higher than that of nylon

stronger intermolecular forces

state three ways in which the monomer units of a protein differ from those of nylon-6,6

* protein monomers are amino acid whereas nylon monomers are diamine
* protein monomers have have different types whereas monomers have two types
* protein monomers are chiral whereas nylon

outline how the polymer is formed from the monomer molecules

* pi bond breaks
* many molecules join forming a long chain

Polymer D is more likely to be a ‘degradable polymer’ than polymer c

* c=o absorbs radiation
* ester linkage hydrolysed
