The signal at 4 ppm corresponds to the two hydrogens of methylene (-O-C[H.sub.2]-) next to the carbonyl group of PHA (a); the signal at 3.6 ppm corresponds to the four hydrogens of the ethoxy units (-0-C[H.sub.2]-C[H.sub.2]-O-) of PEGMA (i); the signal at 2.3 ppm corresponds to -CH- of the backbone of PHA (g), the overlapping signals at 1.6 were assigned to -C[H.sub.2]- of the backbone of PHA (f) and PEGMA (f'), the overlapping signals at 1.3 ppm corresponds to the -C[H.sub.2]-C[H.sub.2]-C[H.sub.2]- groups of PHA chains (b, c, and d), and finally, signals at 0.9 ppm correspond to the methyl groups in PHA and PEGMA (e and h, respectively).
The OTPS silane consists of more reactive ethoxy groups to form a bond with the silanol groups on the silica surface compared to the MPDTS silane.
In this study, the ethoxy groups of TESPT were hydrolyzed and changed to silanol groups which could react with the hydroxyl groups of RHF.
(10) Ethoxy 2-(naphthalen-1-yl-diazenyl)-3-(phenethylimino)but-l-en-l-ol (7b).
It has been reported that the primary step in the silanization process is the hydrolysis of ethoxy groups in APTES molecules, which leads to the formation of ethanol and silanols [22-25].
evaluated the antimycobacterial activities of 1(2-hydroxyethoxy)methyl-5-(1-azido-2-haloethyl or 1-azidovinyl) analogs and 1-[(2-hydroxy-1-(hydroxymethyl) ethoxy)methyl-5-decynyluracil and 1-[(2-hydroxy-1-(hydroxymethyl) ethoxy)methyl]-5-dodecynluracil against M.
In stober process, due to the hydrolysis process, the ethoxy groups are replaced by TEOS; the hydrolysis reaction initiates by the attachment of hydroxyl anions on TEOS molecules [6,7].
In the previous work [23], a simple method was applied to prepare coated silver nanoparticles based on modified 6-propylene-4-nonyl-phenol ethoxy maleate, Noigen R-N10, polymerizable surfactant which was used as dispersing agent for silver nanoparticles.
(15-23) Ekin and coworkers studied the effect of siloxane molecular weight and content on the physical and fouling-release properties of siloxane-polyurethane coatings made using a polycaprolactone (PCL) polyol, diluting the PDMS in ethyl ethoxy propionate (EEP).(15), (19), (20) Pieper et al.
