|Title:||Acrylate-α-Pinene Copolymer as Biodegradable Multifunctional Additives for Lube Oil|
|Keywords:||Lube Oil Additive;Pour Point Depressant;Viscosity Index Improver;Viscosity Index Improver|
|Abstract:||Copolymer of α-pinene (AP) with dodecyl acrylate (DDA) and myristyl acrylate (MA) were synthesized and characterized by spectral analysis (IR, NMR). Thermal stability was measured by thermogravimetric and average molecular weight by gel permeation chromatographic (GPC) analysis. Their performance as pour point depressant (PPD) and viscosity index improver (VII) was tested in two different base oils. DDA - AP copolymer showed better performance over MA – AP copolymer. In addition, introduction of α-pinene (AP) structure in the acrylate backbone has induced significant biodegradability in the copolymers. Homopolymers of dodecyl acrylate (HPDDA) and myristyl acrylate (HPMA) were also synthesized, characterized and evaluated in lube oils to make a comparison with their respective AP - copolymers.|
