Polysulfide Rubber is typically obtained from which compound?

Explanation:
Polysulfide rubber is formed from sulfur-containing polysulfide salts, with sodium polysulfide being the typical starting material. In its production, sodium polysulfide undergoes polymerization to create long chains that contain sulfide (S–S) linkages, yielding a sulfur-rich elastomer known for chemical resistance and fuel tolerance. The other options—ethylene, propylene, and benzene—are feedstocks for different types of polymers (polyolefins or aromatic aromatics) and do not produce polysulfide rubber.
