Abstract:
A composition containing ETFE and PAS in a weight ratio of 5-95/95-5 and further containing an organic onium compound in a weight ratio of the sum of the above two polymers to the onium compound of 80-99.99/20-0.01.
Abstract:
Described is a method of improving the heat-insulation properties of Cu/I-based polyamide using systems containing 0.1 to 1.0 % by wt. of quaternary phosphonium iodides which cannot be easily washed out. After rinsing and dyeing, filaments produced by this method exhibit a loss in tear strength, determined in an 8 h/177 DEG test, of less than 17 % relative to untreated fibres. In addition to filaments, the method is suitable for use with fibres, sheets and moulded articles.
Abstract:
Polymer masterbatch compositions, the production and use thereof, as well as vulcani- zable rubber compounds comprising these masterbatch compositions, and their use for the production of moldings in the production of tires.

A polymer electrolyte composition containing an ionic group-containing polymer (A), a phosphorus-containing additive (B), and a nitrogen-containing aromatic additive (C), the phosphorus-containing additive (B) and the nitrogen-containing aromatic additive (C) being a compound represented by specific structural formulae.
Abstract:
The invention relates to flame retardant compositions comprising heptaphosphorus-derived compounds and to novel heptaphosphorus-derived compounds. These heptaphosphorus-derived compounds are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamides, or polyesters and duro-plastic polymers, such as the ones based on polyepoxides.
