Synthesis of Polymers from Fatty Alcohol and Acrylic Acid and its Impact on Tribological Properties

Synthesis, characterization, and performance evaluation of N,N‐Dimethylacrylamide–alkyl acrylate copolymers as novel multifunctional additives for lube oil

“…Anticorrosion additive is another important class of the additive to be included in the additive package to combat this issue. [9] Two alkylacrylate copolymers with different mole fractions of comonomers synthesized by free radical mechanism were used as pour point depressant (PPD) additives. Hence, growing demand, requirement of high performance characteristics and increasing environment-related concerns have forced the researchers to develop new multifunctional polymeric additives.…”

“…Furthermore, all additives showed antiwear (AW) and extreme pressure (EP) properties. [9] Two alkylacrylate copolymers with different mole fractions of comonomers synthesized by free radical mechanism were used as pour point depressant (PPD) additives. [10] The copolymers of iso-decyl methacrylate and 1-decene were synthesized and evaluated for the potential use as viscosity modifiers in lubricant compositions in comparison to a normal poly(alkyl methacrylate) (PMA).…”

“…Maleic anhydride copolymers with n‐alkyl acrylates were synthesized and further reacted to n‐butylamine to form poly (n‐acrylate‐co‐n‐butylmalemide) and utilized as viscosity index improver and pour point depressant additives in conventional base stock (150N and 500N). Furthermore, all additives showed antiwear (AW) and extreme pressure (EP) properties . Two alkylacrylate copolymers with different mole fractions of comonomers synthesized by free radical mechanism were used as pour point depressant (PPD) additives .…”

Fatty Acid-Based Radically Polymerizable Monomers: From Novel Poly(meth)acrylates to Cutting-Edge Properties

“…For instance, Khalkar et al have successfully synthesized several n-alkyl acrylates by simply reacting equimolar amounts of different FAl (including lauryl, myristyl, palmityl, and stearyl alcohols) with acrylic acid in toluene at 120 °C in the presence of p-toluenesulfonic acid as catalyst. 29 Efficient and more eco-friendly alternative method of esterification catalyzed with Novozym 435 lipase (from Candida unfurctica) was also reported for the preparation of acrylate monomers from stearyl and oleyl alcohols. 30 According to the efficiency of the functionalization, the process was extended to their methacrylate analogues by using methacrylate acid instead of acrylic acid.…”

“…Fatty alcohols (FAl) result mostly from the hydrogenation of FAs or fatty esters (FEs). , Since they contain hydroxyl groups, they can be easily functionalized with various (meth)­acrylate functions by (trans)­esterification (Scheme ). For instance, several n -alkyl acrylates have been synthesized by simply reacting equimolar amounts of different FAl (including lauryl, myristyl, palmityl, and stearyl alcohols) with acrylic acid in toluene at 120 °C in the presence of p-toluene­sulfonic acid as catalyst . An efficient and more eco-friendly alternative method of esterification, catalyzed by Novozym 435 lipase (from Candida antarctica ), was also reported for the preparation of acrylate monomers from stearyl and oleyl alcohols .…”
