Abstract: A carbonate (meth)acrylate composition contains 99 to 99.99 mass % of carbon (meth)acrylate and 0.01 to 1 mass % of an ascorbic acid derivative represented by formula (1), in the formula (1), R1, R2 and R3 independently represent a hydrogen atom, an alkyl group having a carbon number of 1 to 20 or an acyl group having a carbon number of 1 to 20, respectively.

Abstract: (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.

Abstract: An object is to provide a wax dispersant capable of improving the resin composition in the fluidity in a molten state, the transparency and the storage stability, when adding the wax to a thermoplastic resin. The wax dispersant is a copolymer (A) which has a copolymerization composition comprising structural units respectively derived from: an aromatic monomer (A1) within 40 to 94% by mass; a (meth)acrylic acid long chain alkyl ester (A2) represented by the formula (1) (an alcohol residue R2 is C9 to C22 alkyl) within 5 to 40% by mass; and a (meth)acrylic acid alkyl ester (A3) represented by the formula (2) (an alcohol residue R4 is C1 to C8 alkyl) within 1 to 20% by mass, and also has a weight average molecular weight within 3,000 to 50,000.
