Monoglycerides (MGs) have been incorporated into the matrix of poly(glycerol-co-glutaric acid) films to investigate their effect on the thermal, mechanical, and solvent absorption properties of the resultant films. Solvent absorption studies revealed that poly(glycerol-co-glutaric acid-co-MG) films were able to absorb and resorb solvents better than poly(glycerol-co-glutaric acid) films, albeit they had higher erosion levels. Thermogravimetric analysis showed that the incorporated MGs did not affect the thermal stability of the glycerol-based films. The MG-incorporated films were observed to be much softer than the poly(glycerol-co-glycerol) films which was further proven by a 39-fold reduction in Young's Modulus and 17-fold reduction in fracture energy when compared to the poly(glycerol-co-glycerol). Mechanical property studies also revealed that the incorporation of MGs increased the elongation % and reduced the tensile strength of poly(glycerol-co-glutaric acid) films. Correlation analysis revealed a strong linear relationship between Young's Modulus and fracture energy (R2 = 0.9962), and between Young's Modulus and tensile strength (R2 = 0.9972). Our study proved that MGs can be successfully incorporated in the polymer matrix of poly(glycerol-co-glutaric acid) films to produce softer films with increased elongation and increased solvent absorption capacity. © 2017 Wiley Periodicals, Inc.
