Polysulfide copolymer particle and method of preparing the same

The present invention relates to a latex composition for dip-molding and a molded article produced therefrom. More specifically, the composition not only has gentle syneresis, and excellent tensile strength, elongation and modulus, and excellent durability against perspiration, but also is capable of preparing the dip-molded articles having excellent wearing sensation.

Latex composition for dip molding, and molded product manufactured therefrom

Provided is a latex composition for dip forming which includes 100 parts by weight of a nitrile-based hybrid latex including a first latex and a second latex which have different glass transition temperatures, and 2 parts by weight to 8 parts by weight of an ion-conductive polymer having a weight-average molecular weight of 400 to 1,000. The latex composition for dip forming has excellent low-temperature stability and a dip-formed article prepared using the composition has excellent tensile strength and elongation. Since wearing comfort is improved due to a decrease in modulus, the dip-formed article may be suitable for industries requiring such properties.
