Abstract:
POROUS PELLETS OF A POLYESTER PREPOLYMER, SUCH AS POLY(ETHYLENE TEREPHTHALATE), ARE PREPARED BY DISPERSING AN INERT GAS OR FOAMING AGENT IN A MOLTEN PREPOLYMER AND EXTRUDING AND PELLETIZING THE THUS SATURATED PREPOLYMER TO CONVENTIONAL PELLET SIZE, (1/16" TO 1/2") OR TO OTHER PARTICULATE SHAPES. THESE POROUS PARTICLES CAN BE FURTHER POLYCONDENSED IN SOLID STATE, UNDER CONVENTIONAL POLYCONDENSATION CONDITIONS, WITHOUT THE NECESSITY OF REDUCING PARTICLE SIZE BELOW 20 MESH.

Abstract:
2098995 9212222 PCTABS00014 Alkylated diphenyl ethers, alkylated diphenyl methanes, alkylated phenoxathins and alkylated diphenyl sulfides are high-temperature stable lubricant fluids having excellent low temperature viscometrics, and excellent additive solubility. These adducts may be used as such as lubricants or may be blended with other lubricant fluids or fuel compositions.
