Sažetak
Oil-soluble poly(methacrylate) based polymer additives play a significant role in lubricating base oil properties improvement, where increased viscosity at elevated temperatures ensures sufficient lubricity over a broad temperature range. Methacrylates with medium size lateral alkyl groups (C10 –C14) enhance viscosity index and those with the long chain groups (C16-C18) mostly contribute to the lowering of the pour point of solutions, whereas the methyl group contributes to the stiffness of the polymer chain. To simulate industrial process, polymerizations were conducted in batch reactor directly in base oil. Mixture of monomers (different methacrylates: methyl methacrylate, N, N-dimethylaminoethyl methacrylate, dodecyl methacrylate, octadecyl methacrylate and styrene) was added to mineral or synthetic polyalphaolefin base oil and in this way, after the polymerization, product is ready for dilution and packaging. Chain transfer agent and different initiator types were used to tailor the product toward more shear stable additive with lower molar mass. To confirm the molar mass of polymers gel permeation chromatography was used. We developed an industry ready process that can be used to synthetize wide range of polymer additives having different molar masses.
