| 摘要 |
This copolymer latex is obtained by an emulsification polymerization of a monomer containing 20-69.5 wt% of an aliphatic conjugate diene monomer, 0.5-20 wt% of an ethylenically unsaturated carboxylic acid monomer, and 10.5-79.5 wt% of an ethylenically unsaturated monomer that can be copolymerized therewith, such that the peaktop molecular weight (Mp) obtained by gel permeation chromatography of the carboxyl group component that is not bonded to the latex particles is 15,000 or less. |
