Plastisols, which are a blend of poly(vinyl chloride) resin and a plasticizer (DEHP), were used as a toughening agent of a resol resin in order to improve the mechanical properties. It was not possible to formulate resol ...

The influence of the condensation temperature on the phenolic resol resin prepolymer formation was studied by liquid chromatography and carbon nuclear magnetic resonance (13C NMR) spectroscopy. Four resols catalyzed with ...

Two organically modified (Cloisite® 30B and 10A) and one unmodified clay (Cloisite® Na) were added to a resol-type phenolic prepolymer. The modified montmorillonites showed a better dispersion in the prepolymer. The ...

The reduction of phenol and/or formaldehyde consumption during phenolic resin synthesis is of great technological and scientific interest because of its economic and environmental implications. In this work, the addition ...

The thermal degradation behavior of resol, several vegetable fibers (two types of cotton fibers, sisal and sugar cane bagasse) and derived polymer composites have been investigated using thermogravimetric analysis (TGA). ...

Epoxy-amine was blended with two resol resins to study the influence of the fined network and void content on the water absorption of these systems. To characterize the network structure of the blends, infrared analyses ...

Reducing the consumption of phenol during synthesis of phenolic resins is of great technological and scientific interest because of its economic and environmental implications. In this work, the use of hydroxymethylated ...

Las ligninas son polímeros polifenólicos naturales obtenidos principalmente como subproducto en la industria papelera. En la actualidad, las ligninas se utilizan como reemplazo parcial de fenol que es un recurso no ...

Vegetable fibers like cotton, sisal, and sugar cane bagasse have been used as reinforcement in a polymeric matrix. Because of its low cost and affinity with lignocellulosic fibers, a phenol-formaldehyde resin —resol— was ...
