- Polyacrylonitrile
- Polyterephthalate
- Low density polyethylene
- High density polyethylene
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
- Low density polyethylene (LDPE) is made by free radical polymerization of ethylene. It is prepared under high pressure and with a catalyst like triethylaluminium and titanium tetrachloride.
- LDPE has a high degree of branching, making it less dense and more flexible.
Thus, the correct answer is (3), Low density polyethylene.
- LDPE has a high degree of branching, making it less dense and more flexible.
Thus, the correct answer is (3), Low density polyethylene.
