In polymer chemistry, what is the general result of polymerisation?

• A. Many monomers joining to form one polymer
• B. A single molecule breaking into many parts
• C. A solvent being consumed
• D. A catalyst being consumed

Answer: (A)

Polymerisation mainly results in many small monomer units joining together to form a single, large polymer molecule. Picture a long chain built from repeated units, like beads strung one after another. This is true for the common types of polymerisation, whether simple addition polymerisation (where monomers add to a growing chain) or condensation polymerisation (where small molecules are released as the chain forms)—the defining outcome is the formation of a polymer from many monomers. It’s not about a single molecule breaking apart, nor about a solvent being consumed, nor about a catalyst being consumed as the defining result of the process.
