摘要： An exemplary embodiment provides a method for preparing a latex composition for dip forming, the method including: (a) preparing a monomer mixture including a conjugated diene-based monomer, an ethylenically unsaturated nitrile monomer and an ethylenically unsaturated acid monomer; (b) introducing an additive including an inorganic solvent, an emulsifier and starch into the monomer mixture; and (c) preparing a copolymer latex by polymerizing the monomer mixture, wherein a content of the starch is 0.1 to 4.9 parts by weight with respect to 100 parts by weight of the monomer mixture.
