- The bonding between chains results in polymers which are stronger and have a higher Tg.
- The elasticity can increase or decrease
- The chains impact how polymer chains slide past one another, thereby impacting the final polymer properties.
- Generally, branching increases strength, toughness and Tg.
- Polymer side groups often contain elements such as chlorine and nitrogen, but they can also be hydrocarbons.
- Side chains can be used to custom-create polymers with very specific properties.

Impact of Structure on Tm and Tg
Like most polymer properties, the melting(Tm) and glass transition temperatures(Tg) are heavily impacted by the polymeric structure. Check out how each aspect of the polymer structure influences the glass transition and melting temperature:
