Abstract

Abstract: Three copolymeric and two homopolymeric additives were synthesized utilizing the C18 alkyl acrylate (C18Ac) and N, N ‐dimethylacrylamide (DMAA) monomers. Three additives named as additive1, additive2, and additive3 were synthesized by varying the ratio between C18Ac: DMAA as 1:1, 1:2 and 2:1 respectively by free radical polymerization using AIBN (azobis(isobutyronitrile)) as initiator, whereas additive4 and additive5 were the homopolymers of C18Ac and DMAA, respectively. All the synthesized polymers were characterized by FT‐IR (fourier transform infrared spectroscopy), NMR (nuclear magnetic resonance), and GPC (gel permeation chromatography) analysis. Performance evaluation of the copolymers as viscosity index improver (VII), pour point depressant (PPD), antiwear, antifriction, and anticorrosion additives in polyol base oil was done by standard methods. As far as the VII, anti‐wear, antifriction, and anticorrosive properties are concerned, additive2 revealed best performance; however, none of the above synthesized additives was found to be suitable for PPD activity.
