Molecular Design and Shear Stability Correlations of Dendritic Polymethacrylates

Journal Article Cosimbescu, Lelia ; Malhotra, Deepika ; Campbell, Kristen B. ; ... - Molecular Systems Design and Engineering

Highly branched poly(alkyl methacrylate)s with and without crystalline polycaprolactone segments were designed and prepared via a core-first strategy from commercially available hyperbranched cores, then evaluated with respect to their rheology and shear stability performance. The main focus of this work was to study the effect of branching on mechanical shear stability, as it relates to the durability of viscosity index improvers. A secondary goal was to study the influence of the side chain length and polycaprolactone segment on rheology and shear stability. The polymers were prepared from 16, 32, 64-arm functionalized macroinitiators then subsequently subjected to AGET-ATRP (Activator Generated bymore »« less

What is the effect of lipophilic polymeric ionic liquids on friction and wear?

Journal Article Bapat, Abhijeet P. ; Erck, Robert ; Seymour, Bryan T. ; ... - Reactive and Functional Polymers

In this work, methacrylate-type ionic liquid (IL) monomers containing a quaternary ammonium cation and two different counter-anions were synthesized and used as co-monomers to obtain functional poly(alkyl methacrylates) (PAMAs) as friction and wear reducing additives for lubricants. The effect of molecular weight, polymer topology (random or diblock), and IL counter anion on friction and wear behavior of polymer PAO (poly-alpha olefin) solutions have been investigated. The results were compared to those of PAO solutions additized with a small molecule, non-polymeric ionic liquid, or non-ionic copolymers containing 2-(dimethylamino)ethyl methacrylate (DMAEMA) as the polar comonomer. No clear correlation between polymer molecular weightmore »« less

Polymer Architecture: Does it Influence Shear Stability?

Journal Article Cosimbescu, Lelia ; Robinson, Joshua W. ; Page, Jordan P. - Industrial and Engineering Chemistry Research

Hyperbranched and linear poly(alkyl methacrylate)s with and without polycaprolactone grafts were designed and prepared via a core-first strategy, then evaluated with respect to their rheology and shear stability performance. The focus of this work was to study the effect of architecture on mechanical shear stability, as it relates to lubricant performance. The polymers were prepared from functionalized macroinitiators subsequently subjected to ATRP/ARGET-ATRP conditions with dodecyl methacrylate and 2-ethylhexyl methacrylate mixtures. As expected, most compounds displayed an increased viscosity index along with increasing molecular weights. The inclusion of polycaprolactone appears to have enhanced the viscosity index in select samples. Although themore »« less

Multifunctional Tunable Polymethacrylates for Enhanced Shear Stability and Wear Prevention

Journal Article Campbell, Kristen B. ; Erck, Robert ; Swita, Marie S. ; ... - ACS Applied Materials & Interfaces

This paper describes the design, synthesis and characterization of linear, polar and non-polar polymethacrylates tuned for use as viscosity index improvers with enhanced shear and anti-wear resistance. The polymers were prepared via Reversible Addition-Fragmentation Chain Transfer (RAFT) to obtain relatively low, narrow, molecular weights, with random polar moieties. The resulting polymers were evaluated with respect to their rheology to determine their viscosity index and shear stability performance, and antiwear characteristics. The polymers had molecular weights (Mw) ranging from 120-170 kDa, and the resulting viscosity indexes (VIs) in general tracked the Mw. Although the VIs were modest (140-189), all polymers displayedmore »« less

Low Molecular Weight Polymethacrylates as Multi-Functional Lubricant Additives

Journal Article Cosimbescu, Lelia ; Vellore, Azhar ; Shantini Ramasamy, Uma ; ... - European Polymer Journal

In this study, low molecular weight, moderately polar polymethacrylate polymers are explored as potential multi-functional lubricant additives. The performance of these novel additives in base oil is evaluated in terms of their viscosity index, shear stability, and friction-and-wear. The new compounds are compared to two benchmarks, a typical polymeric viscosity modifier and a fully-formulated oil. Results show that the best performing of the new polymers exhibit viscosity index and friction comparable to that of both benchmarks, far superior shear stability to either benchmark (as much as 15x lower shear loss), and wear reduction significantly better than a typical viscosity modifiermore »« less
