“…The ester yield reached a remarkable 94.7% under ideal reaction conditions [46]. from poly(vinylbenzyl chloride)-sodium abietate and polymethacrylate from poly(glycidyl methacrylate)-abietic acid [47,48]. The addition of rosin into polymer significantly enhances mechanical and chemical qualities, including hardness and resistance to chemicals.…”

Gum rosin is an important agricultural commodity which is widely used as a raw material for various industries. However, gum rosin has low stability, crystallizes easily, and tends to oxidize. This is due to carboxyl groups and conjugated double bonds in gum rosin’s structure. Therefore, to reduce these weaknesses, it is necessary to modify the rosin compound to achieve better stability via the esterification process. This paper surveys esterification agents such as glycerol, pentaerythritol, methanol, ethylene glycol, polyethylene glycol (PEG), allyl group, and starch Rosin ester. The product is used in the manufacture of pressure-sensitive adhesives, drug delivery, solder flux for electronic devices, as a plasticizer, and as a coating agent in fertilizers. In general, the esterification reaction between alcohols and carboxylic acids is very slow without a catalyst. Heterogeneous catalysts have the advantage of controlling size, structure, spatial distribution, surface composition, thermal-chemical stability, and selectivity. Among the catalysts for gum rosin esterification are ZSM-5, Fe3O4, ZnO, Calcium, TiO2, Kaolin, and Al2O3, among others. Different catalysts and esterification agents can produce various physical and chemical properties of rosin ester and will result in specific rosin ester products, such as glycerol ester, pentaerythritol ester, methyl ester, glycol ester, allyl ester, and acid starch-based rosin.

In this study, a new 5-phenyl-1,3,4-thiadiazole-containing vinyl monomer and its polymer were synthesized. The characterizations of the ligand, monomer and polymer were carried out using FTIR, UV-Vis, 1 H-NMR, elemental analysis and gel permeation chromatography techniques. The roughness average, root-mean-square roughness, surface skewness and surface kurtosis parameters of the poly(PTMPMA) film were found to be 1.98 nm, 2.84 nm, 1.529 and 5.777, respectively. Effects of the annealing temperature on optical properties of the poly(2-(((5-phenyl-1,3,4-thiadiazole-2-yl)imino)methyl)phenyl methacrylate) (PTMPMA) were investigated. The important optical parameters such as refractive index, optical band gap, angle of incidence, imaginary part of optical conductivity and real part of dielectric constants of the poly(PTMPMA) decrease and other important optical parameters such as excitation and dispersion energy, angle of refraction, real part of optical conductivity and imaginary part of dielectric constants of the poly(PTMPMA) increase with increasing annealing temperature. The absorption band edge values of the polymer films were found to be 2.34, 1.85 and 1.74 eV for 298, 523 and 643 K, respectively. The optical band gap values of the polymer films were found to be 3.314, 2.943 and 2.917 eV for 298, 523 and 643 K, respectively. The poly(PTMPMA) can be used as an active polymer layer in production of the electronic devices such as polymer diodes and metal-semiconductor contacts.Electronic supplementary material The online version of this article (

“…Kim W S et al 5 provided a method to synthesize poly (vinylbenzyl abietate) using poly(vinylbenzyl chloride) and sodium abietate as raw materials. Kim T H et al 6 reported the synthesis of polymethacrylate upon the reaction of poly(glycidyl methacrylate) with abietic acid. In these two methodologies, resin derivatives were not used as monomers in the polymerization.…”

We have developed a facile method for production of allyl resinate monomer (allyl rosin ester) via a phase transfer reaction under microwave irradiation. The synthesis of allyl resinate was conducted using allyl chloride and sodium resinate as starting materials in aqueous solution at 50 • C for 30 min with a yield of 94.7%, which is 20% higher than conventional heating method. The products precipitated spontaneously from the aqueous phase after reaction, which significantly facilitated the subsequent separation of monomer products. The synthesized monomer product appeared as a viscous liquid, with a viscosity of 460 mPa•sat25 • C and a density of 1.0469 g/cm 3. The physical and chemical properties suggested that the synthesized monomer has great potential for free radical polymerization.
