Question
Thiokol is a highly chemical-resistant synthetic rubber used in tank linings and rocket fuels. What are the specific monomers used in the condensation polymerization to produce Thiokol rubber?
Answer: C
💡 Solution & Explanation
Thiokol is a unique polysulphide rubber synthesized via a step-growth mechanism (condensation) between ethylene chloride ($Cl-CH_2-CH_2-Cl$) and sodium polysulphide ($Na_2S_4$), eliminating $NaCl$ as a byproduct.
