Answer:
Characteristics of polymers:
1. High corrosion resistance
2.Lower density
3.Cost of production is low
4.Specific strength is high.It means that weight to strength ratio is high that is why polymer light in weight.
5.Polymer can be handle easily
6.Polymers have resistance to thermal and electric conductance.
The categories of polymers
1. Elastomers
2. Brittle plastics
3.Plastics
The strain stress curve for different polymers.
