摘要： (Object) When a cyclocarbonate group-containing (meth)acrylate monomer is applied for a polymer used as a paint or the like, it is to provide the cyclocarbonate group-containing (meth)acrylate monomer in which the increase of the viscosity over time is suppressed so that it can used stably for a long time. (Solution) It is provided a cyclocarbonate group-containing (meth)acrylate monomer (A) represented by a formula (1) as follows, wherein a content of di(meth)acrylate monomer (B) represented by a formula (2) as follows is 3 weight % or lower. (R1 represents hydrogen atom or methyl group, R2 represents an alkyl group having a number of carbons of 2 to 10, and X is 0 or 1.) (R3 represents hydrogen atom or methyl group, R4 represents an alkyl group having a number of carbons of 2 to 10, and X is 0 or 1.)

摘要： Disclosed is an additive for lubricating oil, which comprises a phosphite ester compound (A) having a specific structure and a phosphite ester compound (B) having a specific structure, wherein a mass ratio of the phosphite ester compound (A) to the phosphite ester compound (B) (phosphite ester compound (A):phosphite ester compound (B)) is 99:1 to 80:20. According to the present invention, it is possible to provide an additive for lubricating oil, capable of imparting wear resistance and demulsibility with respect to a base oil for lubricating oil, and to impart durability even in the presence of water.
