Y-aminopropyl triethoxysilane

Lee [242] studied the dependence of the physico-mechanical properties of Wollastonite-filled polychloroprene rubber on the type of agent used to pre-treat the filler. The composition contained 26.9 part (weight) of the filler per 100 parts (weight) of the rubber (compositions CR-1100, CR-174, CR-151). The finishing agents were y-aminopropyl triethoxysilane (CR-1100 and CR-174) and vinyl triethoxysilane (CR-151). The mechanical properties of the compositions are listed in Table 7 below. The author proposed an empirical equation to relate the modulus with the equilibrium work of adhesion in the following form ...

The corresponding 1,3,5-triazines are even more reactive. Triallyl-cyanurate (135) reacts readily at room temperature with butylamine (74GEP2308560) or -y-aminopropyl triethoxysilane to the corresponding monoamino derivatives 136 and 137 in nearly quantitative yield... 

In the lactate analyzer HER-100 (Omron Tateisi, Japan) an asymmetric cellulose acetate membrane is used, bearing LOD covalently bound by -y-aminopropyl triethoxysilane and crosslinked by glutaralde-hyde (Tsuchida et al., 1985). The membrane is highly selective for hydrogen peroxide. The analyzer has been employed for lactate assay in...

Engelhardt and Mather [29] synthesized a similar HPSEC support by reacting silica with amides that had been synthesized from y-aminopropyl-triethoxysilane. The resultant supports exhibited good SEC properties and protein recoveries. Because the organosilane reactions cited before are reversible, the coatings can slowly leach with use, especially under acidic conditions. It was observed that when a column of similarly derivatized silica was placed before an analytical column, the bonded phase would actually transfer and extend the lifetime [30]. 

Factor analysis had previously been used by Culler et al. [100] for quality control monitoring of a polymeric composite system of y-aminopropyl-triethoxysilane (j/-APS) coupling agent on an E-glass mat substrate. In this system, factor analysis successfully indicated the number of pure components, extracted the spectra of the pure components, indicated the relative concentrations of spectra, and improved the S/N ratio in the extracted spectra. The construction of a calibration curve allowed factor analysis to be used as a QC monitor of the amount of coupling agent on the E-glass mats. 

Silylation of borosilicate with APTS (Y-aminopropyl)triethoxysilane) was attempted as a tool to improve its incorporation in PI (polyimide) films (Vankelecom et al. 1996). This was achieved by a minimal coverage of zeolite crystals with APTS, as evidenced by the characterization of silylation through xylene sorptions, NMR spectroscopy, and measurements of the specific surface of the zeolites. Silylated zeolite was incorporated in PI films on which tensile strength, density, and xylene sorption were measured. Indeed, the density and tensile strength measurements on these composite PI membranes proved a better incorporation of borosilicates after silylation with APTS without changing xylene sorption.
