Vedclass · Answer

(B) $1$. $Dacron$ (also known as $Terylene$) is a polyester polymer.$2$. It is formed by the condensation polymerization of ethylene glycol $(HO-CH_2-CH_2-OH)$ and terephthalic acid $(C_6H_4(COOH)_2)$.$3$. During the formation of the polymer, the carboxylic acid group of the acid and the hydroxyl group of the alcohol react to form an ester linkage $(-COO-)$.$4$. Therefore, $Dacron$ contains an ester linkage.
