Title : Comparative between newly prepared copolymers with their nano-composits as flow Improver for lubricating oil

Abstract:

Lubricating oil is an essential product of energy so the goal of this work is modifying the petroleum lubricating oil. In this work the copolymers (CPs); hexadecylmethacrylate-dodecene (CP₁) and hexadecylmethacrylate-hexadecene (CP₂) was laboratoryly synthesized through solution polymerization of the synthesized ester of  hexadecylmethacrylate with 1-dodecene or 1-hexadecene. The nano-composite of these polymers NCPs; hexadecylmethacrylate-dodecene-NMMT (NCP₁) and hexadecylmethacrylate-hexadecene-NMMT (NCP₂) was synthesized through the emulsion polymerization of the same reactants of the prepared CPs with adding the nano-montmorolonite. FTIR and ¹HNMR was achieved to prove the success preparation CPs and NCPs, TGA to prove the thermal stability of these polymers also TEM and DLS was achieved for the nanocomposite polymers. The prepared polymers were applied as pour-point-depressant (PPD), flow-improver (FI), a lubricating oil viscosity modifier (VM) to show high efficiency of all polymers, then the results was compared between the CPs and NCPs for proving the modification of the nanocompsites at all the results. The pour-point was depressed from 0 ^oC (blank) to -15, -21, -21 and -27 ^oC for CP₁, CP₂, NCP₁ and NCP₂ respectively at 10,000 ppm of them. The viscosity-index elevated from 86.57 (blank) to 89.31, 90.87, 91.02 and 92.47 for CP₁, CP₂, NCP₁ and NCP₂ respectively.

Audience Takeaway Notes:

• Preparation copolymers and their nanocomposite
• Application these polymers and their nanocomposite as pour point depressant (PPD)
• The lubricating oil is essentially used in industry.
• Modification of this lubricating oil with these additives.
• The nanocomposite show high efficiency as viscosity modifiers and PPD.
