lubricious layer at the metal surface and are recognized as a better lubricants. Another significant application for C16 - C18 olefins is in paper sizing. Linear alpha olefins are, once again, isomerized into linear internal olefins are then reacted with maleic anhydride to make an alkyl succinic anhydride(ASA), a popular paper sizing chemical. C20 - C30 linear alpha olefins production capacity is only 5-10% of the total production of a linear alpha olefin plant. They are used in a number of reactive and non-reactive applications, including as feedstocks to make heavy linear alkyl benzene (LAB) and low molecular weight polymers which are used to enhance properties of waxes.
