Copolymer latex and composition containing the same and application product therof |
摘要 |
To provide a copolymer latex having a small particle size, which has a sufficient adhesion strength as a binder and a low viscosity and excellent handling properties in a composition containing a filler and the like, a composition for coating paper using the copolymer latex, and a coated paper having a coating layer formed by the composition.;A copolymer latex contains a copolymer comprising: (A) 20 to 80% by mass of a structural unit derived from an aliphatic conjugated diene monomer, (B) 4 to 15% by mass of a structural unit derived from an unsaturated carboxylic acid monomer, and (C) 5 to 76% by mass of a structural unit derived from other copolymerizable monomer, wherein the total of (A), (B) and (C) being 100% by mass, and has a number average particle size of 30 to 80 nm by measurement with a transmission electron microscope, and has a viscosity of 50 to 400 mPa·s at a solid content of 48% by mass. |

1. A copolymer latex containing a copolymer comprising:
(A) 20 to 80% by mass of a structural unit derived from an aliphatic conjugated diene monomer, (B) 4 to 15% by mass of a structural unit derived from an unsaturated carboxylic acid monomer, wherein the unsaturated carboxylic acid monomer contains 0 to 1% by mass of a dicarboxylic acid, and (C) 5 to 76% by mass of a structural unit derived from other copolymerizable monomer, wherein the total of (A), (B) and (C) being 100% by mass, the copolymer latex having a number average particle size of 30 to 80 nm by measurement with a transmission electron microscope, and having a viscosity of 50 to 400 mPas at a solid content of 48% by mass, wherein said copolymer is produced by batch-polymerization. |
