1.	Whatare LDF are HDPE ? Howare they prepared ?
Answer» Solution :LDPE is LOW densitypolyethylene and HDPE is highdensity polyethylene. LDPE is preparedby polymerisationof ETHENE at temperatureof `200^(@)C` and high pressureof 100 atm in the presence of peroxideinitiator .It isa branched CHAIN polymer. HDPE is prepared bypolymerisationof ethene at a temperaturebelow `100^(@)C` and pressureless than 100 atm is the presenof Ziegler - Natta CATALYST. Itis a linear polymer .
