synergistic effect of liquid crystals on the additive performance of poly acrylate in lubricating oil

Multifunctional additive performance of the poly acrylate at the presence of the selective liquid crystal structures was evaluated using the standard astm methods. homopolymer of the mixed acrylate (octyl, decyl and dodecyl) was synthesised and characterized by thermo gravimetric, spectroscopy and viscometric analysis. additive performances of the polymer were evaluated as the viscosity modifier (vm), thickening agent (ta), pour point depressant (ppd) and antiwear (aw) additive. physical blend of the polymer with six different types of liquid crystals (lc) were also made, and their performance was evaluated. the results indicated that all the lc-blended samples acted as a better vm, ppd, along with excellent aw and thickening performance compared with the pure polymer sample.
