A slot liner for a stator assembly in one embodiment includes a mesh structural member and a coating. The coating is disposed on at least one side of the mesh structural member, and includes a mixture of a filler and a polyimide resin. The filler is a high thermal conductivity electrical insulating (HTCEI) filler, and includes particles of at least one of boron nitride, aluminum nitride, or a diamond material.

Stator slot liners

Disclosed herein are methods of curing silicon carbide precursor polymer fibers, such as polysilazanes, using moisture and free radical generators, such as peroxides. Also disclosed are methods of forming, curing, and using silicon carbide precursor polymers that contain alkenyl groups and free radical generators, such as peroxides.

A slot liner for a stator and/or a rotor of an electric machine includes a body configured to be received within a stator slot and/or within a rotor slot. The body extends from a first end to an opposite second end and from a first edge to an opposite second edge. The body includes an inner segment and first and second outer segments that extend along the body. The first and second outer segments flank the inner segment such that the inner segment extends between the first and second outer segments along the body. The inner segment includes at least one different material such that a thermal conductivity of the inner segment is greater than a thermal conductivity of the first and second outer segments.

Slot liner for an electric machine

The present disclosure generally relates to methods of using boron-containing additives for crosslinking polysilazane green fibers, which are precursors to silicon carbide fibers. These methods provide a controllable process for crosslinking silicon carbide fibers while providing a simple way for the introduction of boron as a sintering aid into the polymer structure.

Methods of using boron-containing additives as silicon carbide crosslinking agents

Disclosed is a method for removing a neutral or an ionic guanidine compound from aqueous media optionally comprising an alkali metal halide, wherein the method is selected from the group consisting of (a) adsorption onto a carbonaceous adsorbent, (b) adsorption onto a clay adsorbent, (c) filtration through a nanofiltration membrane, and (d) removal of water and calcination.

Method of forming a dry quaternary ammonium salt mixture

Disclosed is a method for preparing an alkali metal salt of a hydroxy-substituted hydrocarbon which comprises the steps of (i) contacting in solvent media at least one hydroxy-substituted hydrocarbon with a base comprising an alkali metal cation; and (ii) devolatilizing the solvent media comprising alkali metal salt by adding or spraying the solvent media into a substantially water-immiscible organic solvent, said solvent being at a temperature greater than the boiling point of solvent media at the prevailing pressure. In one embodiment the solvent media comprises water, and optionally at least one water-soluble protic organic solvent.

Method for making salts hydroxy-substituted hydrocarbons

An emulsion polymerization process for the preparation of polybutadiene grafted with styrene and acrylonitrile monomers in a reaction system is provided. The resultant product has a low end content of unreacted residual monomers, low yellowness index, and improved impact strength. The diene rubber is prepared via a process wherein a chain transfer agent is added on a continuous basis to give a rubber substrate having a low crosslink density. In one embodiment of the invention, the process includes charging the reaction system with a pre-selected diene emulsion with a low crosslink density, adding a first portion of at least one of a styrene monomer and acrylonitrile monomer to the diene emulsion, adding to the reaction system, over a predetermined time, an initiator and a second portion of acrylonitrile and styrene monomer, and polymerizing the catalyzed reaction mixture of diene substrate, styrene and acrylonitrile to form ABS graft polymers. In another embodiment, a third monomer is added after the conversion rate of the monomers is greater than 98%.

Enhanced polymerization process

Disclosed are weatherable polyester soft block copolymer compositions comprising copolymers of resorcinol or alternatively phenol, aromatic dicarboxylic acid, and a aliphatic dicarboxylic acid based structural units. These polyester soft block copolymers comprise a substantial proportion of direct linkages between the resorcinol or alternatively the phenol, and the aromatic dicarboxylic acid based structural units, the balance of the linkages being between resorcinol and the aliphatic dicarboxylic acid based structural units.

Weatherable copolymers

Quaternary salts having a double helix structure are prepared by the reaction of dihydroxyaromatic compound, preferably a bisphenol, with an alkali metal hydroxide and a quaternary salt, such as a tetraalkylammonium or hexaalkylguanidinium chloride. The quaternary salts and their alkaline hydrolysis products are useful as catalysts in various reactions, including imide formation from bisphenol salts and halo- or nitro-substituted phthalimides and redistribution and equilibration of polycarbonates.
