摘要:
The invention relates to flame retardant polymer compositions with (thio)phosphinyl- iminophosphorane compounds as active component. These compositions are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamines or polyesters, and particularly duroplastic polymers, such as polyepoxides.

This invention provides processes for forming powders comprising at least one active compound and at least one carrier. The processes comprise (i) heating at least one active compound to at least its melting point or softening point; and (ii) in an extruder, combining at least the at least one active compound with at least one carrier, to form combined ingredients, and cooling the combined ingredients as they pass through the extruder, such that the combined ingredients exit the extruder at about ambient temperature in the form of a powder having particles sized so that about 95 wt% or more of the powder passes through a screen of about 8 standard U.S. mesh.

摘要:
A method of forming an encapsulant layer for a photovoltaic cell module including a photovoltaic cell layer and an outer layer spaced from the photovoltaic cell layer comprises disposing a silicone composition having a kinematic viscosity of from greater than 0 to less than about 1,000 centistoke (cSt) at 25 °C between the photovoltaic cell layer and the outer layer. The method further comprises polymerizing the silicone composition in situ between the photovoltaic cell layer and the outer layer, thereby forming the encapsulant layer in the photovoltaic cell module.
摘要:
The present invention relates to a semi- IPN (interpenetrating polymer network) type solid polymer electrolyte composition containing a cyclotriphosphazene-based crosslinking agent and a plasticizer. Since the crosslinking agent according to the invention forms a semi-IPN (Interpenetrating Polymer Network) type three dimensional network structure and the solid polymer electrolyte composition containing the crosslinking agent of the invention lowers crystallization of an ethyleneoxide group of a plasticizer side chain even at low temperature, ion conductivity is dramatically improved. In addition, the invention can be used as a solid polymer electrolyte such as a lithium-polymer secondary battery, a dye-sensitized solar cell, a fuel cell, etc. due to excellent electrochemical and thermal stability.
