what is polymer? explain low density of polythene in brief
Answers
Answer:
Polyethylene is vinyl polymer, made from the monomer ethylene. Here's a model of the ethylene monomer.
Explanation:
Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene, produced in 1933 by Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. Its manufacture employs the same method today.

Answer:
polymer is a large molecule, or macromolecule, composed of many repeated subunits. Due to their broad range of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.
Explanation:
LDPE is defined by a density range of 0.917–0.930 g/cm3. ... Also, because its molecules are less tightly packed and less crystalline due to the side branches, its density is lower. When exposed to ambient solar radiation the plastic produces two greenhouse gases, methane and ethylene
