A) 1-B, 2-A, 3-D, 4-E
B) 1-C, 2-D, 3-A, 4-B
C) 1-D, 2-C, 3-B, 4-A
D) 1-E, 2-C, 3-A, 4-B
E) 1-E, 2-C, 3-B, 4-A
Correct Answer: E
Solution :
Buna-N is a polymer of acrylonitrile \[(C{{H}_{2}}=CH(CN))\]and butadiene \[(C{{H}_{2}}=CH-CH=C{{H}_{2}})\] Nylon-6,6 is a polymer of hexamethylene diamine\[(N{{H}_{2}}{{(C{{H}_{2}})}_{6}}N{{H}_{2}})\]and adipic acid\[(HOOC-{{(C{{H}_{2}})}_{4}}-COOH)\]. Dacron (terylene) is a polymer of terephthalic acid and ethylene glycol\[(HOC{{H}_{2}}-C{{H}_{2}}OH)\] Glyptal plastic is a polymer of phthalic acid and ethylene glycol\[(HOC{{H}_{2}}-C{{H}_{2}}OH)\]You need to login to perform this action.
