Vedclass · Answer

(B) Elastomers are polymers that possess elastic properties,typically due to weak intermolecular forces and cross-linkages. Nylon-$6,6$ is a fiber,not an elastomer; it is a polyamide formed by the condensation polymerization of adipic acid and hexamethylenediamine. Artificial silk (rayon) is indeed derived from cellulose. Natural rubber is a polymer of isoprene ($2$-methyl-$1,3$-butadiene). Both starch and cellulose are natural polysaccharides composed of glucose units. Therefore,the statement that Nylon-$6,6$ is an elastomer is false.
