Estimating the term…
The present invention relates to a carbonic acid-modified nitrile-based copolymer latex, a process for producing the same, a latex composition for dip-molding comprising the latex composition and a molded article produced therefrom. More specifically, modified nitrile-based copolymer latex, which can improve the stability of latex even with the use of inorganic pigments by making the inherently modified nitrile-based copolymer latex, enables the production of a dip-molded article having a smoothness of syneresis, less stickiness, and excellent tensile strength, a process for producing the same, a latex composition for dip-molding comprising the same, and a molded article made therefrom.
A carbonic acid-modified nitrile-based copolymer latex which is produced adding starch during copolymerization and has a glass transition temperature of −50 to −15° C. and an average particle diameter of 50 to 500 nm, wherein the starch has a weight-average molecular weight of 300 to 30,000 g/mol.
