“…On the other hand, PAM imparts a good viscosity/temperature behavior to the lubricating oil and at high concentration it shows excellent wear protection property 39 . Also the advantages of modification of lubricating oil with PAM additives was studied by Mysak et al, which shows PAM additive reduces mechanical friction losses at low temperature, owing to adsorption on the surface and forming a thin film in the boundary friction 40 . Therefore, polymers with controlled architecture which imparts higher VI and better low temperature fluidity without destroying shear stability are highly essential.…”

Methyl methacrylate (MMA) functionalized polyethylene additives for improving the properties of lubricating oil has been investigated in which poly(MMA-co-ethylene) were synthesized by using three different polymerization techniques such as miniemulsion, post polymerization and reverse atom transfer radical polymerization with 1.0 molL À1 of MMA and 20 bar of ethylene pressure. The copolymers are block in nature with the composition of 1:3 molar ratios of ethylene:MMA which is independent of polymerization techniques used. 1 H NMR analysis confirmed the successful incorporation of the copolymers in the lubricating oil. Thermogravimetric analysis reveals that the addition of poly(MMA-co-ethylene) increases thermal stability of the additive doped lubricating oil by approximately 40 C with a single stage decomposition pattern. Flash point measurements show an increasing flash point values for copolymer doped lubricating oil. From rheological study, the viscosity index of base lubricating oil has found significant increases from 102 to 129 with the addition of poly(MMA-co-ethylene) and the higher molecular weight (MW) of this copolymer provides better thickening efficiency. However, copolymer with higher MW seems to be more susceptible to mechanical degradation resulting in lower shear stability whereas copolymer with lower MW acts as a better pour point depressant.

This paper reports a kinetic investigation into the emulsion (co)polymerization of decyl meth-and decyl acrylate with methyl acrylate for the first time. The obtained results are used to prepare copolymers based on the products of the emulsion (co)polymerization. It is determined that decyl methacrylate does not homopolymerize with the formation of emulsions regardless of the nature of an emulsifier, its solubility and initiator structure. Moreover, they reduce the rate of copolymerization with methyl acrylate. The deceleration of the copolymerization in the presence of long-chain monomers is related to the a low activity of decyl (meth)acrylate as compared with methyl acrylate. The colloid-chemical and physicochemical properties of the synthesized dispersions are investigated. The position of the maximum of the dependences of viscosity and surface tension on the polymer composition coincides with the smallest particle sizes of the dispersion; hence, the alterations in the viscosity and surface tension of the dispersion are associated with the variations in particle sizes, which results in the changes in the interface surface area. The molecular weight distribution of emulsion copolymers is studied by a turbidimetric titration technique. The absorption of water, the strength and specific elongation of the (co)polymer films are determined by tension testing. Diffusion coefficients are calculated according to the first section of the water absorption curve; the obtained values show the deceleration of the rate of the water absorption by the copolymer film as compared with the polymethylacrylate films. The tensile strength of the poly(methyl acrylate-co-decyl acrylate) films is less than that of the poly(methyl acrylate-co-decyl methacrylate) ones, which corresponds with the well-known facts concerning the influence of a methyl substituent in an -position on the polymer properties. The addition of hydrophobic co-monomers, decyl meth-and decyl acrylate, to the structure of macromolecules with methyl acrylate strongly affects the properties of the dispersion and derived films, which is connected with the significant structural transformations of macromolecules in the dispersions and films.
