The aim of the present paper is to find out a suitable stabilizer for natural rubber latex foam. For this, condensatioii reactions of formaldehyde with various aliphatic amines and with ethyl chloride were carried out to obtain polyamine-type polynieric products. The resultant products were characterized and evaluated for their stability effects in the natural rubber latex foam. In addition to this, efforts were successfully made to find out an effective formulation to get a foam of maximum strength and durability. The majority of the products synthesized were unable to make the foam stand satisfactorily for a critical duration of time; however, one exhibited an excellent stabilization effect in such foams. It is a triamine-type polymeric base prepared by a new route.
