Abstract: A dispersion of polymer particles in organic liquid having a narrow range of particle sizes. The dispersion is produced by polymerizing monomer in organic liquid in the presence of a preformed stabilizer. The stabilizer is made by condensing a compound A with a compound B. Compound A is solvatable by the organic liquid, has a molecular weight of 500-5,000 and has a group capable of condensation reaction. Compound B has a molecular weight of at least 250, is not solvatable in the organic liquid, has different polarity from compound A and includes a group capable of condensation reaction with compound A. The weight ratio of compound A to compound B in the stabilizer is 0.5 : 1 to 5 : 1.

Abstract: 1. A LIQUID HYDROCARBON FUEL OF FLASH POINT AT LEAST 90* F. SUITABLE FOR USE IN GAS TURBINE ENGINED AIRCRAFT, AND HAVING A REFUCED TENDENCY TO PARTICULATE DISSEMINATION ON BEING SUBJECTED TO SHOCK, THE FUEL CONTAINING THEREIN POLYMER OF MOLECULAR WEIGHT GREATER THAN 10**6 (VISCOSITY AVERAGE) OR OF INTRINSIC VISCOSITY REATER THAN 2.5 DLS./GM. IN A CONCENTRATION SUCH THAT THERE IS MOLECULAR OVERLAP OF THE POLYMER MOLECULES IN THE LIQUID, THE DISSOLVED POLYMER CONTAINING POLAR GROUPS WHICH FORM INTER-MOLLECULAR ASSOCIATIVE BONDS ARISING FROM ELECTROSTATIC ATTRACTION BETWEEN POLAR AND/OR DIPOLAR CHARGES IN THE POLAR GROUPS, THE BONDS BEING HYDROGEN OR ELECTOVALENT BONDS, THE POLYMER BEING AN ADDITION COPLYMER OF AN ALKYL STYRENE, THE ALKYL GROUP IN WHICH CONTAINS FROM 3 TO 20 CARBON ATOMS.
