This work describes polymerization by inverse suspension of acrylamide monomers and acrylic acid for forming homopolymers or copolymers. This type of polymerization’s advantages are described and reasons given for why it should be studied. The article stresses the importance of these types of monomer for obtaining materials presenting great affinity for water, such as super-absorbents and controlled liberation mechanisms. Important aspects are presented such as type of initiation, monomer composition and continuous phase composition; parameters are described offering an important basis for formulating a system leading to successfully obtaining the desired materials. The final part (relying on data found in the literature) describes dependence on some of the synthesized materials’ most relevant characteristics such as particle distribution and size, polymerization kinetics, conversion and water absorption capacity respecting the system’s modifiable parameters. The foregoing is important since the product can be modified, bestowing properties on it which are suitable for its use.
Este trabajo describe el proceso de polimerización por suspensión inversa de los monómeros acrilamida y ácido acrílico para la formación de homopolímeros o copolímeros. Se describen las ventajas de este tipo de polimerización y por qué es importante su estudio. Se recalca la importancia de este tipo de monómeros para la obtención de materiales que presentan gran afinidad por el agua como los superabsorbentes y los dispositivos de liberación controlada; se presentan aspectos importantes como el tipo de iniciación, la composición de la fase de monómeros y composición de la fase continua, describiendo parámetros que ofrecen una base importante para la formulación del sistema que conllevan a la obtención exitosa de los materiales deseados.
En la parte final, por medio de datos hallados en la literatura, se describe la dependencia de algunas de las características más relevantes de los materiales sintetizados, como la distribución y tamaño de partícula, cinética de polimerización, conversión, y la capacidad de absorción de agua con respecto a parámetros modificables del sistema. Lo anterior es importante ya que así se puede modificar el producto confiriéndole propiedades adecuadas para su utilización.
