摘要：
Polydecylacrylate (PDA) is synthesized, characterized (FT-IR and NMR), and evaluated for its performance as anti wear (AW), pour point depressant (PPD), viscosity modifier (VM), and thickening agent in lube oil of different compositions. In addition physical blend of it with liquid crystal (LC) of cholesteryl benzoate (CB) is also made and evaluated, and the data is compared. Molecular weight of the prepared polymer and that of it blends was determined by viscometric analysis. The blends showed better efficiency to act as multifunctional (AW, PPD, VM) additives compare to the pure homopolymer in lubricating oil.
