Y-Methacryloxypropyl trimethoxy silane

Fig. 2. Schematic diagrams of (a) a polysiloxane deposit on glass fibre M is the methacry-loxypropyl group in y-methacryloxypropyl trimethoxy silane and (b) the composite interface. Here R-M is the interpenetrating copolsmer with the resin matrix (R), ( ) is the dissolved binder and/or size PS = polysiloxane, HBS = hydrogen bonded oligomeric silanes. IPN = intapenetrating network, INT = interface...

The silica is well bonded to the matrix using 0.3 wt% (on filler) of a silane coupling agent (y-methacryloxypropyl (trimethoxy) silane) for both sets of composites. 

A copolymer of glycidyl methacrylate (GMA) and y-methacryloxypropyl trimethoxy silane (y-MPS) was used to prepare a series of hybrid anion exchange membranes. The epoxy groups of the methacrylate contained in the copolymers were converted to quaternary ammonium groups through reaction with trimethylamine. The trimethoxysilyl...
