Answer

Condensation polymers involve the elimination of small molecules during formation

Explanation

Condensation polymers are defined as polymers formed through reactions that eliminate small molecules, such as water, while addition polymers are formed without such elimination. This key difference is crucial when considering the synthesis of various types of plastics and fibers. Condensation polymers apply in the formation of materials like nylon and polyesters, where the reaction leads to the release of water.

Common mistake

Distinguishing Addition and Condensation Polymers

Students often confuse addition polymers with condensation polymers, thinking they are the same because both involve multiple monomers.

Addition polymers are formed through the addition of unsaturated monomers (like alkenes) without the loss of any small molecules, while condensation polymers are formed by the reaction of monomers with the loss of small molecules (like water). Remember that addition polymers involve only C=C bonds, whereas condensation polymers involve functional groups that can react to release small molecules.
