To improve the chemical stability of a latex of natural rubber has a low content of ammonia.

摘要

The invention relates to the chemical stability of a latex of natural rubber has a low content of ammonia. / p & & p & the chemical stability of the latex and of the formulations of latex of natural rubber has a low content of ammonia is improved by the addition of 0,1 has 0,5partie by weight based on solid, for 100parties by weight of natural rubber based on solid, of a surfactant which is an anionic phosphate neutralized or partially neutralized with a ph of 4 to 10 in the form of an aqueous solution at 20. / p & & p & the latex or formulations of latex of natural rubber stabilized resulting are particularly adapted to be used in the preparation of formulations prevulcanized of immersion.
