“…However, the viscosity of pure VE resins is too high for them to be used for common processing technologies. Therefore, VE resins typically need 35–50 wt% of styrene as a low‐viscosity co‐monomer to decrease the viscosity of the resin formulation and copolymerize with VE resin . However, new emission standards for composite manufacturing by the Environmental Protection Agency specifically target styrene as a volatile organic compound (VOC), hazardous air pollutant (HAP) and a potential human carcinogen.…”

A renewable chemical, eugenol, is methacrylated to produce methacrylated eugenol (ME) employing the Steglich esterification reaction without any solvent. The resulting ME is used as a low‐viscosity co‐monomer to replace styrene in a commercial epoxy‐based vinyl ester resin (VE). The volatility and viscosity of ME and styrene are compared. The effect of ME loading and temperature on the viscosity of the VE–ME resin is investigated. Moreover, the thermomechanical properties, curing extent and thermal stability of the fully cured VE–ME thermosets are systematically examined. The results indicate that ME is a monomer with low volatility and low viscosity, and therefore the incorporation of ME monomer in VE resins allows significant reduction of viscosity. Moreover, the viscosity of the VE–ME resin can be tailored by adjusting the ME loadings and processing temperature to meet commercial liquid molding technology requirements. The glass transition temperatures of VE–ME thermosets range from 139 to 199 °C. In addition, more than 95% of the monomer is incorporated and fixed in the crosslinked network structure of VE–ME thermosets. Overall, the developed ME monomer exhibits promising potential for replacing styrene as an effective low‐viscosity co‐monomer. The VE–ME resins show great advantages for use in polymer matrices for high‐performance fiber‐reinforced composites. This work is of great significance to the vinyl ester industry by providing detailed experimental support. © 2018 Society of Chemical Industry

“…14 A presença de diferentes grupos na estrutura do eugenol possibilita a preparação de uma gama de substâncias, a citar: poliacetilenos, 15 copoliésteres aromáticos 16 e copolímeros multibloco, 17 os quais se aplicam na indústria de polímeros (Figura 2). Além disso, o uso do eugenol apresenta benefícios para o setor industrial e a sociedade, uma vez que pertencer ao grupo de compostos monoaromáticos livres, enquadrando-se no âmbito de recursos renováveis, 18 O interesse da comunidade científica pelo eugenol é justificado pelo fato do mesmo ser utilizado como material de partida na síntese de diversos produtos naturais e bioativos, 8 como, por exemplo, na síntese do: 6-Gingerol 21 , Cimiracemate B 22 , Imperanene 23 , Obovatol 24 e XH-14 25 (Figura 4).…”

Eugenol is a natural product found in greater quantity in the Eugenia Caryophyllata and exhibits a wide variety of biological and pharmacological applications, making it a product of great commercial interest. Motivated by its applications, this work aimed to investigate the technological potential and the scientific interest of this compound through an analysis of patents databases and indexed journals. The searches were carried out in three patent banks, on the Web of Science platform, and the statistical study was based on the ARIMA (1.1.0) model. The majority of the patent records related to the researched technology had been filed in the Espacenet database and dealt mainly with agriculture and dentistry. A constant linear growth in the number of records of patents granted could be observed over the years, with a remarkable dominance of patents recorded by China (107) followed by the United States (47) and Brazil (22). The h-index for the term eugenol was 107.2 and there was a growing trend of increased patent deposits for the next 50 years. In short, there is great scientific and technological interest, and a strong trend towards increased patent deposits for the next few years on eugenol.

“…Thiol–ene chemistry was used to prepare antibacterial and antioxidant bio‐based networks that were derived from linalool and eugenol . In this work, a photoinitiated thiol–ene reaction of linalool, a terpene constituent of lavender essential oil, was used in combination with allyl derivative eugenol and trimethylolpropane tris(3‐mercaptopropionate) under solvent‐free conditions to give renewable materials with high cross‐linking densities.…”
