Abstract
Process for obtaining expandable synthetic thermoplastic substances, able to acquire by heating a cellular structure by introducing an expanding agent into finely subdivided particles of said thermoplastic synthetic substance maintained in aqueous suspension, characterized by comprising the preparation of an aqueous suspension of said particles of synthetic thermoplastic substance, with use, as suspension stabilizer system, of a mixture consisting of a water-soluble organic suspending agent and an organic ionic wetting agent preferably associated with an alkali salt strongly dissociated in aqueous solution, the addition to said suspension of the blowing agent at a temperature higher than the softening point of the thermoplastic synthetic substance, and maintaining said suspension under the aforementioned conditions for a sufficient time to carry out the introduction of the expanding agent into the particles of thermoplastic synthetic substance.
