Polymers Lesson 2 - Structure and Properties

Which of the following are found in the structure of a polymer?

• Chains

• Grains

• Brains

• Lanes

Which of the following types of chains would be found in a thermo plastic?

• Cross linked chain

• Branched chain

• Laminated chain

• Continuous chain

Which type of chain would be found in a thermosetting plastic?

• Branched chain

• Continuous chain

• Cross linked chain

• Linear chain

Thermosetting Plastics

• Can be reshaped using heat and pressure.

• Are lighter plastics

• Can be recycled

• Can not be reshaped using heat and pressure

The type of chain structure shown here is referred to as a

• Mesh chain

• Branched chain

• Cross linked chain

• linear chain

The term degree of polymerisation refers to

• The length of polymer chain.

• How well the plastic has been educated.

• The number of atoms in the monomer.

• The strength of the bonds in a polymer chain.

The properties of Polymer is determined by

• Monomer

• Temperature

• Pressure

• All of above

Q. Rigid and very strong Polymer.

• Linear

• Branched

• Cross-Linked

• Thermoset

Which of the following is a branched polymer?

• Low-density polyethylene (LDPE)

• High-density polyethylene (HDPE)

Thermoplastics have strong cross links between polymer chains.

• True

• False
