Question

The two monomers used in the preparation of dextron are:

• A. 3-hydroxy butanoic acid and 3-hydroxy pentanoic acid.
• B. $ϵ$ amino caproic acid and glycine.
• C. isobutylene and isoprene.
• D. lactic acid and glycolic acid.

Answer 1

The correct option is D lactic acid and glycolic acid.

Dextron is a polyacetic acid polyglycolic acid polymer. The monomers used are lactic acid and glycolic acid. It is copolymer and has ester linkage. It is used as friction modifier. It is added to lubricants to reduce surface friction.
