Synthesis of Eugenol–Lauryl Methacrylate Copolymers via Cationic Polymerization

Abstract

Eugenol is one of the most abundant natural resources in Indonesia. The recently bio-based polymer resin is created based on eugenol because eugenol is functionalized with the polymerizable group. In order to improve the functional properties of eugenol, in this research Eugenol–Lauryl Methacrylate copolymers (co-poly(Eg-LMA)) were synthesized by cationic polymerization using H2SO4 as an initiator under the nitrogen atmosphere. Structure identification of the copolymer showed the absorption of the vinyl group from the monomers disappear at the analysis through FTIR at the wave number 1637-1639 and 985-995 cm-1 and also 1H-NMR on the chemical shift 5,97 and 5,08 ppm. The resulting copolymers obtained brown powder in 32.03 % yieldsand melting point at 96 – 97 °C. Solubility test of the co-poly(Eg-LMA) showed that the polymer couldnot soluble in water but soluble in chloroform, diethyl ether, and benzene. Average molecular weight of co-poly(Eg-LMA) Led Ostwald viscometry was obtained 42020 with the degree of polymerization by 200.

Sustainable and Biodegradable Copolymers from SO2 and Renewable Eugenol: A Novel Urea Fertilizer Coating Material with Superio Slow Release Performance

“…The proton NMR showed that the chemical shift at 3.92 ppm is a proton signal of the methoxy­(−O–CH 3 ) group. The identification of successful polymerization processes in poly­(eugenol sulfone) was demonstrated by the loss proton signal of the vinyl eugenol group at 5.00–6.00 ppm, and the appearance of chemical shifts at 1.00–2.50 ppm, which are proton signals for a double bond from a vinyl group that changes to a single bond . Based on the above identification, it is known that poly­(eugenol sulfone) has been successfully synthesized. , …”

“…Data analysis and processing were performed using Map Info 9.0 software. The research results showed that the most ideal shape is trapezium made from soil with a cross-sectional area of 0.86 m 2 , the upper channel width of 1.5 m, the width of the canal base 0.65 m, 1.05 m high, and slope 45° [23].…”

Eugenol, a Promising Building Block for Biobased Polymers with Cutting-Edge Properties

“…There are a few examples of cationic copolymerization of eugenol in the literature. Eugenol and lauryl methacrylate copolymers were obtained by Fajrin et al 215 by cationic polymerization using sulfuric acid as initiator. On the other hand, Breloy et al 216 reported the synthesis of a biobased antibacterial coating using both cationic and thiol− ene reaction with eugenol and mono-and diepoxy limonene and with β-carotene as photosensitizer under visible-light irradiation.…”
