Synthesis of 2:1 type 3-(methacryloxy)propyl magnesium (nickel) phyllosilicate

New organic/inorganic hybrid polymers, 2:1 type 3-(methacryloxy)propyl magnesium phyllosilicate and 2: 1 type 3-(methacryloxy)propyl nickel phyllosilicate, were synthesized at room temperature by the copolymerization reaction of [3-(methacryloxy)propyl] trimethoxysilane to metal chloride hexahydrate. These polymers were studied by X-ray diffraction, Fourier-transformed infrared spectroscopy, and nuclear magnetic resonance measurements. The polymers have an inorganic part of phyllosilicate-like structure such as mica or smectite, and organic side chains linked to the inorganic framework through an -Si-C- covalent bond. The layered inorganic parts were considered consistent with well-ordered octahedral sheets and disordered -C-SiO3 tetrahedral sheets. The tendency of magnesium or nickel ions to form octahedral sheets played major part in the formation of the layered structure.
