plastic is of two types
1.HDP(high density polythene)
formed by addition polymerisation of ethene in a hydrocarbon solvent in the presence of catalyst such as triethyl aluminium and titanium tetrachloride ( ziegler-natta catalyst)at 333K to 343K and at a pressure of 6-7 atmospheres
2.LDP (low density polythene )
By the polymerisation of ethene under high pressure of 1000-2000 atmospheres and at a temp. of 350-750K in the presenceof traces of dioxygen and peroxide initiator
