摘要：
Oxidized polyisobutenes, that is polyisobutenes containing ketonic and carboxylic acid carbonyl groups, are produced by passing through a column of the polyisobutene maintained at a temperature in the range from 140.degree. to 200.degree. C. and at atmospheric or elevated total pressure a molecular oxygen-containing gaseous oxidant at a gas flow rate greater than 10 liters cm.sup.-2 h.sup.-1 measured at the operating pressure. The oxidized polyisobutenes can be reacted for example with an aliphatic polyamine to produce a lubricating oil additive or with an aliphatic polyamide and formaldehyde to produce a fuels additive.
