| Resumen: | Las microesferas poseen mayor área superficial que la misma cantidad de monómero polimerizado en masa, lo cual ofrece ventajas de interacción con el medio, bien sea para absorber agua como para otros fines. Su obtención depende de una serie de condiciones específicas que, de no ser apropiadas, puden no reaccionar adecuadamente y precipitarse en masa. Mediante el uso del monómero acrilamida, el entrecruzante N-metilenbisacrilamida, agente iniciador persulfato de amonio, agua como agente de disolución y tolueno como la fase continua, mezclados y agitados en el proceso de polimerización en suspensión inversa, se prepararon hidrogeles en forma de microesferas individuales.

| Abstract: | The microspheres possess major superficial area that the same quantity of polymerized monomer in mass, which offers advantages of interaction with the medium, as much to absorb water as for other purposes. His obtain depends on a series of specific conditions that, if not being apropiated, cannot react adequately and will precipitate in mass. By means of the use of acrilamide monomer, the crosslinker Nmetilenbisacrilamide, the initiator agent ammonium persulfate, water as a dissolution agent and toluene as the continuous phase; all of them mixed and shaken in the process of polymerization in inverse suspension, were prepared hidrogels in individual microspheres shape. |
