Question
- A. They are formed by the reaction of monomers with the release of water
- B. They are formed from unsaturated monomers through the breaking of double bonds
- C. They can only be synthesized from alkenes
- D. They have a lower molecular weight than their monomers
Answer
They are formed from unsaturated monomers through the breaking of double bonds
Explanation
Addition polymers are defined as polymers that result from the polymerization of unsaturated monomers, specifically through the breaking of double bonds. This process does not involve the release of small molecules, which is a defining characteristic of addition polymerization. This applies to common materials like polyethylene, where ethylene monomers undergo addition to form long chains.
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.
