Abstract
The present invention relates to a solidification process of the natural rubber latex by means of polyquaternary polymers. The process of the present invention has the advantage to not require the addition of acids and/or salts, with an evident saving in terms of cost for the reagents. Furthermore, in such a way neither the neutralization step of the rubber nor the treatment of the processing water before their disposal are required. The process of the present invention is suitable both for the continuous and batchwise embodiment, with evident advantages as far as its industrial application is concerned.
