Question

In the synthesis of Butyl rubber, a highly unreactive backbone is desired, but vulcanizability must be maintained. What specific percentage of the diene monomer (isoprene) is copolymerized with isobutylene to achieve this?

Prashant Kotian · Accepted Answer

Correct answer: 2. Butyl rubber is synthesized from a mixture of isobutylene and exactly isoprene. The isoprene provides just enough double bonds for subsequent vulcanization.
