Question

Select the statements applicable to LDPE.

• A. It has high degree of branching
• B. It has low density
• C. It is made using the free-radical mechanism
• D. It is used to make plastic bags.

Answer 1

Answer: (A), (B), (C), (D)

It is used to make plastic bags.

LDPE stands for low-density polyethene.

It has low density because of a high degree of branching. The high branching makes it stack less and leads to lower density.

As a result, LDPE is translucent and has low tensile strength. It is made using the free-radical mechanism of polymerisation.

It is used to make plastic bags.
