These poly(2-alkyl-2-oxazoline) silane coupling agents were copolycondensed with tetraethoxysilane by acid-catalyst to produce poly(2-alkyl-2-oxazoline)-modified silica gel. The composite gel from 2-ethyl-2-oxazoline was also homogeneous and transparent glass. Poly(2-alkyl-2-oxazoline)-modified silica gels, especially gels based on poly(2-ethyl-2-oxazoline) absorbed water and also organic solvents such as DMF or alcohols as shown in Table 7. This result means that the obtained composite gel shows the amphiphilic adsorption property. 

Another highly effect chain extender is trimellitic anhydride (TMA) which gives rise to branching of the PET structure. Note that the multifunctional epoxies (see Table 14.2) react quickly with the terminal carboxylic acid groups of PET but can also react with the film former and the silane coupling agent on glass fibre reinforcements.

Silane coupling agents. Monomeric and polymeric silane coupling agents were purchased from Petrarch Systems Co. (Bristol, PA) and used without further purification. Their chemical structures are given in Table 1. APS was obtained as the neat compound, and the polymeric silanes were supplied as 50% solution in isopropanol. The silanes were diluted to the required concentration in chosen solvents for application on fibers. 

Table 1 lists the silane coupling agents that were used and their methods of application to the melamine foil. Considerable difficulty was encountered in trying to obtain a thin uniform layer on the highly porous melamine foil the methods listed in Table 1 represent the final iteration in a series of tests. 

Glass fibers and fabrics are commercially available with silane treatments. The resulting physical properties and the resistance of the composite to deterioration by water immersion are greatly enhanced by the addition of the coupling agent. Table 10.3 shows the effect of silanes on the dry and wet flexural strength of several composite materials.
