SUMMARY: The interactions of two reactive maleic anhydride copolymers, a styrene maleic anhydride copolymer and an alternating copolymer of malic anhydride and a-olefin side chains, with amino-functionalized surfaces were studied by means of FTIR-ATR spectroscopy. The interfacial processes were detected at a planar surface of a thermally oxidized silicon as internal reflecting element. This ATR element can be understood as a model for a glass fiber which is used as reinforcing material in polymer matrices. A typical glass fiber coupling agent, c-aminopropyltriethoxysilane (c-APS), was used to functionalize the silicon dioxide layer. It was found that the amino groups of the amino siloxane network layer, which were obtained by a coating procedure with c-APS, react with the anhydride groups of the copolymer melt to form amic acid structures and imide structures depending on the chemical composition of the copolymers and the temperature.

“…It is appropriate to determine this working window for a given purpose rather than to rely on literature because different silanes display different reaction rates and because the influence of the (uncontrolled) presence of impurities cannot be underestimated [33,34]. The extent of silane hydrolysis can be monitored by 1 H NMR, while that of condensation can be monitored by 29 Si NMR.…”

“…Nuclear magnetic resonance spectroscopy (NMR) 1 H NMR measurements were performed on a Bruker 400 Advance at room temperature, averaging 8 scans with a spectral width of 20.62 ppm and an acquisition time of 1.99 s. Chemical shifts were referenced to the water-hydrogen peak at 4.79 ppm and time between sample preparation and the first measurement was kept as low as possible: i.e. between 165 s and 180 s. 29 Si NMR measurements were done using a Bruker 600 Advance at room temperature, averaging at least 256 scans with a spectral width of 5031.70 ppm and an acquisition time of 0.55 s. Recording 1 spectrum takes at least 2 h, and when discussing results, the time associated with a given measurement refers at the time lapse between preparation of a given solution and finishing of the measurement. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX)-SEM analysis was performed with a JEOL JSM-7000F Field Emission Gun scanning electron microscope with high spatial resolution operated at a 20 kV accelerating voltage.…”

Reacción del γ γ-aminopropiltrietoxisilano (γ γ-APS) con partículas de pizarra Los agentes de acoplamiento silanos son frecuentemente utilizados para modificar superficies de fibras o partículas utilizadas como refuerzo en composites de matriz orgánica. Para comprobar la formación de enlaces resistentes entre los agentes de acoplamiento y las partículas inorgánicas se han empleado muchos métodos experimentales. En este trabajo se ha utilizado la espectroscopía infrarroja por transformadas de Fourier (FT-IR), el análisis térmico diferencial y termogravimétrico (ATD-TG) y el análisis de la superficie específica como métodos para estudiar la reacción del agente de acoplamiento γ-aminopropiltrietoxisilano (γ-APS) con partículas de pizarra y poder conocer la modificación que ha sufrido la superficie después del tratamiento.Palabras clave: Pizarra, γ-aminopropiltrietoxisilano, Interacción. Study of the reaction of γ γ-aminopropyltriethoxy silane with slate particlesSilane Coupling Agents (SCA) are widely used in fibers or particulates reinforced polymer composites to provide a water resistant bond between these reinforcements and the polymer martix. Many methods have been employed to study the interaction of SCA with inorganic surfaces in order to understand if a covalent bonding at the particulates and silane interface exists. In this work it has been used Fourier Transform infrared (FT-IR) spectroscopy, differential thermal analysis (DTA-TG) and specific surface área analysis in order to study the reaction of γ-aminopropiltrietoxisilane (γ-APS) with slate particulates and to know the surfaces changes occurring after treatment.
