| Orthoborate salts suitable for use as electrolytes in lithium batteries and methods for making the electrolyte salts are provided. The electrolytic salts have one of the formulae (I). In this formula anionic orthoborate groups are capped with two bidentate chelating groups, Y1 and Y2. Certain preferred chelating groups are dibasic acid residues, most preferably oxalyl, malonyl and succinyl, disulfonic acid residues, sulfoacetic acid residues and halo-substituted alkylenes. The salts are soluble in non-aqueous solvents and polymeric gels and are useful components of lithium batteries in electrochemical devices. | ||||||

| Unimolecular micelles, generally referred to as cascade polymers, are constructed via the addition of successive layers, or tiers, of designed monomers, or building blocks, that possess a predetermined, branched superstructure consisting of connected physical matter inherently defining an internal void volume or void area within the molecular framework. Each of the branches define a flexible arm from a central core atom and terminate with a hydrodynamic reactive group. A method is described for manipulating such cascade polymers. | ||||||

Disclosed herein are a heat resistant insulated wire which is not decomposed but maintains insulativity under a high temperature with excellent adhesion of a coating film, and a method of preparing the same. The heat resistant insulated wire includes a base material (1) consisting of an electrical conductor, and an insulating layer (2) provided on its surface. The insulating layer (2) is obtained by heating a second polymer, in which main chains expressed in a chemical formula - [Si(R₁)₂ - N(R₂)]n - are cross-linked with each other by chloroborazine through side chains containing trialkylsilyl radicals at a temperature of at least about 300°C and not more than 500°C. |

A process for the production of boron nitride is carried out by condensing a mixture of B-tris(loweralkylamino)borazine with an alkylamine in an inert gas atmosphere at a temperature of 150°C or above to prepare a precursor, forming the precursor into a desired shape and then slowly heating the shaped precursor in an ammonia gas atmosphere until the precursor changes to a white boron nitride product. The shaped boron nitride in the form of a fiber is particularly useful as a reinforcement. |

| A process for preparing tractable preceramic precursors of Group IIIA metal/Group VA nonmetal compounds, such as BN, in which a first reactant containing a Group VA nonmetal to hydrogen bond, such as ammonia or an amine is reacted with a second reactant containing a Group IIIA metal to hydrogen bond, such as a metal hydride, in the presence of a metal catalyst that catalyzes dehydrocoupling of the bonds to form the precursor. Further reaction of the precursor in the presence of the catalyst forms oligomeric/polymeric forms of the precursor. | ||||||
