Answer 4

Natural and Synthetic

Question 5

How are polymers classified in accordance to their class?

Answer 5

Plastics: Solid at room temperature, high molar mass
Rubbers: High elasticity, high resilience
Fibers: Linear macromolecules, filiform structure, high mechanical resistance

Question 6

How are polymers classified in accordance to their structure?

Answer 6

Linear: Self-explanatory
Ramificado: cadeia linear com ramificações
Ligações cruzadas/reticulado: cadeias lineares com ramificações, as cadeias se conectam através das ramificações
Em rede: diversas cadeias fechadas, como azulejo.
