Application: Polymer composition, lubricating oil additive composition, and lubricating oil composition (Patent ID: US20240124638A1)
The patent by Idemitsu Kosan Co Ltd. describes a polymer composition containing a comb-shaped polymer (X) with specific structural units derived from short-chain and long-chain alkyl (meth)acrylates, along with a macromonomer. The composition also includes a hetero atom-containing base oil (Y) with a kinematic viscosity at 40°C of 25 mm2/s or less. The polymer composition can be used as a lubricating oil additive or in lubricating oil compositions, providing specific viscosity and molecular weight ranges for optimal performance.
The patent further details the method for producing the polymer composition, involving polymerization of the alkyl (meth)acrylates and macromonomer to form the comb-shaped polymer (X), followed by dissolution in the hetero atom-containing base oil (Y). The method emphasizes the specific mass ratio of the short-chain alkyl (meth)acrylate in the polymerization process and the required kinematic viscosity of the base oil. By utilizing these precise compositions and methods, the resulting polymer composition can be effectively used in lubricating oil formulations to enhance performance characteristics such as viscosity and lubrication properties.
