Preparation of poly(eugenol-co-methyl methacrylate)/polypropylene blend by creative route approach: structural and thermal characterization

Abstract

Poly(eugenol-co-methylmethacrylate)/polypropylene blends were successfully prepared using methyl methacrylate (MMA), eugenol (Eg) and polypropylene (PP). First, poly(eugenol-co-methylmethacrylate) (poly(Eg-co-MMA)) was synthesized by photopolymerizaiton in one step at ambient temperature and without solvent. Benzophenone and triethylamine were used as photoinitiator and hydrogen donor, respectively. The second stage is the blending approach between polypropylene and poly(Eg-co-MMA) copolymer. The anti-bacterial test was carried out using the agar well diffusion. Escherichia coli, Staphylococcus aureus bacterial species were tested using Clinical and Laboratory Standards Institute (CLSI) Disk-Diffusion method in antibacterial analysis. As a result of these studies, the blend polymers (PEgMMA 1:1 ) 30 -PP and (PEgMMA 1:1 ) 50 -PP showed activity against E. coli Gram-negative bacteria. Zone diameters are 7 ± 0.00 mm and 5.25 ± 0.25 mm for (PEgMMA1:1) 30 -PP and (PEgMMA1:1) 50 -PP, respectively. No activity has been observed against S. aureus bacteria. In antimicrobial tests, it was determined that the polymers did not show a high antibacterial property as expected. Structural characterization and thermal properties of the synthesized terpolymers were performed by FTIR (Fourier-transform infrared spectroscopy), 1 H NMR (nuclear magnetic resonance spectroscopy), TG-DTG (thermogravimetry-derivative thermogravimetry). SEM (scanning electron microscope) was used for surface analysis. The thermal stability of the synthesized blend polymers was higher than their homopolymers. Structural characterizations and surface analyzes support the successful performance of the synthesis.

Water Sorption, Water Solubility, and Rheological Properties of Resin-Based Dental Composites Incorporating Immobilizable Eugenol-Derivative Monomer

“…Besides its immobilizability within the base matrix of restorative dental composite, EgGMA may preserve the desirable properties of free Eg molecule [ 11 ], thus supporting its application as a potential biomaterial. Moreover, the allylic double bond can, to some extent, be involved in the polymerization reaction, thus increasing the degree of crosslinking [ 7 , 8 , 12 ], the property that is closely pertinent to mechanical as well as to most of the physicochemical properties, including sorption and solubility of the composite.…”

UV Curable Coatings Based on Urethane Acrylates Containing Eugenol and Evaluation of Their Antimicrobial Activity

“…Therefore, it was seen in studies present in the scientific literature that suitable functional groups are added to eugenol and its derivatives to prevent the inhibition. However, when this situation was evaluated in terms of time, energy, and waste generation, it was evident that it brings additional costs and disadvantages [31]. Polymerization studies after the modification of eugenol are frequently encountered in the literature but, in this form, they usually lose their antimicrobial properties.…”

Synthesis, characterization, thermokinetic analysis and biological application of novel allyl glucosamine based glycopolymers

“…Methacrylic monomers with pendant saccharide residues [ 29 ], has been deployed for synthesising methacrylic glycopolymers [ 30 ],such as 3- O -methacryloyl-1,2:3,4-di- O -isopropylidene- d -galactopyranose [ 31 ],3- O -methacryloyl-1.2,5.6-diisopropylidene- d -gluco-furanose [ 31 ], and monomethacroyl-sucrose [ 32 ]. They were homopolymerised or copolymerised via atom-transfer radical polymerization [ 33 ] or free-radical methods initiated with 2,2-azobisisobutyronitrile (AIBN) [ 25 ]. AIBN was used as the initiator in this study because it has the advantage of not producing oxygenated by-products and undesirable color changes.…”
