Abstract
A liquid jet fuel composition comprising: PA1 (a) a major portion of a liquid fuel; and PA1 (b) a minor effective portion of a thermal stabilizing additive prepared by PA2 (i) reacting a polyamine, an aldehyde and a phenol containing active hydrogen to form a phenol - aldehyde - amine condensate; and PA2 (ii) reacting said phenol - aldehyde - amine condensate and a succinic acid anhydride bearing a polyolefin - derived substituent containing residual unsaturation, thereby forming a phenol - aldehyde amine Mannich condensate polyamine succinimide product additive; and PA1 (iii) recovering said product additive.
