-
The biodegradable polymer is:Nylon 2-nylon 6 is a biodegradable polymer (an alternating polyamide copolymer of glycine and amino caproic acid). Nylon-6,6, nylon-6 and Buna-S are non-biodegradable.
2015 AIPMT-I 1 question
-
Biodegradable polymer which can be produced from glycine and aminocaproic acid is$H_2N-CH_2-COOH$ (glycine) + $H_2N-(CH_2)_5-COOH$ (aminocaproic acid) $\xrightarrow{-H_2O}$ $\left[-NH-CH_2-CO-NH-(CH_2)_5-CO-\right]_n$
This alternating polyamide is nylon-2-nylon-6, a biodegradable polymer.
2012 AIPMT-MAINS 1 question
-
Which one of the following sets forms the biodegradable polymer?Glycine ($H_2N-CH_2-COOH$) and aminocaproic acid ($H_2N-(CH_2)_5-COOH$) form nylon-2-nylon-6, an alternating polyamide copolymer that is biodegradable.
Styrene + butadiene gives Buna-S, acrylonitrile + butadiene gives Buna-N and ethylene glycol + terephthalic acid gives dacron; these are not biodegradable.
