Question
High density polyethylene(HDPE) can be prepared from ethylene by
Answer: Option A
:
A
HDPE ispreparedbyco-ordination polymerization whichoccursthroughtheintermediateformationofco-ordinationcomplexes.Forexample,ethylenefirstformsaco-ordinationcomplex with the transition metal titanium by donating its π electrons. The π complex thus formed then reacts stepwise with a large number of ethylene moleculesultimately leading to the formation of a polymer. The polythene so obtained has high density (0.92g/cm3) and higher m.pt.(403K)ascompareto LDPE(density−0.92g/cm3andm.pt.384K)
