Answer 1

Answer: It is a polymer of ehtylene glycol (ethane-1,2-diol) and terephthalic acid(benzene-1,4-dicarboxylic acid). It is obtained by heating a mixture of ehtylene glycol and terephthalic acid at 420K to 460K in the presence of zinc acetate-antimony trioxide catalyst. It is known as terylene or dacron.
