Condensation polymers possess distinct properties, particularly in their formation and molecular characteristics.
Key Properties of Condensation Polymers
Here's a breakdown of the properties associated with condensation polymers:
- Formation Speed: Condensation polymers form more slowly compared to addition polymers. This slower formation is a key characteristic that differentiates them.
- Heat Requirement: Their formation often necessitates the input of heat to facilitate the reaction.
- Molecular Weight: Condensation polymers generally exhibit lower molecular weights compared to addition polymers.
- Active Terminal Groups: The terminal functional groups on a polymer chain remain active. This allows shorter chains to combine into longer chains, especially in the later stages of polymerization.
In summary, condensation polymers are characterized by their slow formation, the need for heat, generally lower molecular weights, and the continued activity of their terminal functional groups in chain lengthening.
