dc.description.abstract | A natural superabsorbent polymer (SAP) material based on an acylated soy protein was studied as a
green alternative to non-biodegradable SAP. In order to obtain the natural SAPs, different amounts of
succinic anhydride were used as acylating agent. Once the functionalized protein was obtained, it was
mixed thoroughly with glycerol and then molded through a lab-scale injection molding device. Water
uptake of samples obtained reached values much higher than those based on unacylated protein.
Moreover, a greater extent of the acylation reaction led to higher water uptake values for the corre sponding SAPs, probably related to their higher hydrophilic character. Water imbibing capacity mea surements and thermogravimetrical analysis (TGA) seemed to confirm this. The presence of larger porous
regions in acylated samples observed in SEM images could also play a role in their higher water uptake
values.
Furthermore, an increase in the extent of acylation reaction led to plastics with lower Young's modulus
and higher extensibility. | es |
