Ceramics from Organometallic Polymers: Industrial Perspectives can be subsequently transformed into the corresponding ceramic structures and shapes. Thus, preceramic polymers can be used to produce ceramic fibers, coatings, whiskers, matrices and powders or as binders in ceramic composite materials. The fields of applications are diverse, ranging from material

Polymerization of Liquid Crystalline Monomersotochemical initiation by onium salts. High molecular mass polymers (M.≤85 000) with a narrow molecular mass distribution (around 2) were produced by cationic polymerization at high temperatures (≤120°C). Ordered 30-50 μm films were produced by polymerization of mesogenic vinyl ether monomers orient

Synthesis of Penta-alkoxy- and Penta-aryloxy Silicates Directly from SiO2 particular, synthetic routes stemming from the use of silica (sand) would be particularly attractive because of the modest cost of pure starting material. To this end, we have developed novel chemistry that offers considerable opportunity as a general synthetic technique for the synthesis of unique

Molecular Composites of the MPS3 Layered Inorganic Polymers: Chemistry, Magnetic and Dielectric Prop Various organic and organometallic intercalates have been synthesized, where the electrical charge of the guest cations is counterbalanced by the removal of an equivalent amount of intralayer M. cations. In contrast to the pristine MPS. materials which behave as typical antiferromagnets, the compos

Chemistry, Structures and Magnetic Properties of Mn(II)Cu(II) Molecular Compounds ; Heterobinuclearand magnetic properties of these compounds present an exceptional diversity. The following situations were encountered: uncoupled carboxylato-bridged binuclear compound, antiferromagnetically coupled oxamido-bridged binuclear compound, alternating bimetallic chain behaving magnetically as binuclear
