文摘

Additives based on polymers of alkyl acrylate used in lubricant composition improve the viscometric and rheological properties of the lubricant and provide fuel economy. However, the recent demand for eco-friendly technology prompted us to develop biodegradable additives for the lubricant formulation. Thus, in anticipation of getting an ideal blend of performance as well as eco-friendly chemistry, the present investigation comprising the incorporation of an 伪-pinene (伪-p) moiety into the acrylate (dodecyl acrylate, DDA, and isodecyl acrylate, IDA) skeleton through copolymerization was undertaken. The analysis of different properties of the polymers indicates that copolymers of 伪-pinene with DDA have more thermal stability and better pour point and viscosity index (VI) values than the copolymers of 伪-pinene with IDA. However, the study of the biodegradability test indicates that the copolymers of 伪-pinene with IDA are better than the other and they show significant biodegradability against the fungal pathogen, Alterneria alernata. In both of the cases, homopolymers are found to be less efficient in performance than the copolymers.
