Which of the following is not required for the production of dacron?(a) 450K temperature(b) Ethylene glycol(c) Terephthalic acid(d) Triethylaluminium-titanium tetrachlorideThe question was posed to me in homework.Query is from Types of Polymerisation Reactions in chapter Polymers of Chemistry – Class 12

Answer»

The correct answer is (d) Triethylaluminium-titanium tetrachloride

Easy explanation: Dacron or terylene is a polyester of ethylene glycol and terephthalic acid. It is PRODUCED by HEATING the TWO at 420-460K and in the presence of zinc acetate-antimony trioxide, which acts as a catalyst. On the other HAND, triethylaluminium-tetrachloride is used in the synthesis of HDPE.
