FIELD: manufacturing technology.
SUBSTANCE: invention relates to a method for producing latexes used for the production of various products by submersible dipping. Latex is obtained in semi-periodic mode, by obtaining a seed latex, adding to the seed latex water, at least one protective colloid, an initiating system, and part of the main mixture of monomers. Main part of the monomers contains 80–85 wt. % of conjugated diene and carboxylate agent of the total amount in the composition of the main mixture and 100 wt.% vinyl monomer selected from vinyl ethers, nitriles and arylolefins, based on the total amount of this monomer in the main mixture. Simultaneously with the monomers, a molecular weight regulator, an emulsifier and a polymerization activator are introduced. 45–75 minutes before the end of dosing the main part of the mixture of monomers in the reaction zone injected the remaining 15–20 wt. % monomers of the main mixture.
EFFECT: latex and its use as a material for the production of various products by submersible dipping is described.
