Question 9

1.       The term rubber refers to any of the natural or synthetic polymers having two main properties: deformation under strain and elastic recovery after vul¬canization. These polymers are called __________.

Question 10

1.      

At a polymeric fire scene, the gases formed depend on the chemical nature of the polymers that have burned or undergone thermal decomposition. Natural polymers having an animal origin contain proteins which in turn are composed of amino acids. Of concern are two amino acids (methionnc and cysteine) as they produce the toxic gases 1) __________ upon decomposition and 2) __________ upon combustion.
