Abstract:
The invention relates to flame retardant compositions that contain mixtures of melamine polyphosphates with layered silicates added to the polymer substrates, particularly polyamides.
Abstract:
The present invention relates to a stabilizer composition comprising a phenolic antioxidant and/or a processing stabilizer together with selected glycidyl(meth)acrylate copolymers and a filled thermoplastic polymer, in particular a nanocomposite. Further aspects of the invention are a process for the stabilization of filled thermoplastic polymers, in particular nanocomposites with a phenolic antioxidant and/or a processing stabilizer together with selected glycidyl(meth)acrylate copolymers and the use of such a composition for the stabilization of filled thermoplastic polymers, in particular nano-composites.
Abstract:
The invention relates to flame retardant compositions, wherein a phosphinic acid hydrazide is present in a polymer substrate. The combination with >NOR-compounds improves the flame retardant properties.
Abstract:
The invention relates to compounds of the group of so-called sterically hindered amines (HALS) which are substituted by phospho groups. The invention also relates to flame retardant compositions wherein these compounds are added to the polymer substrate.
Abstract:
The invention relates to a flame retardant composition, wherein the following components: a) At least one flame retardant component selected from the group consisting of phosphinic acid salts and nitrogen containing compounds; and b) At least one polymeric dispersing agent selected from the group consisting of styrenemaleic acid anhydride copolymers, long chain carboxylic acid salts and aliphatic polyether substituted by acidic groups; and c) A polymer substrate; are present.
Abstract:
The invention, relates to azo-compounds of formula (I), wherein >N-O-R substituted 2, 2, 6, 6- tetraalkyl-piperidyl groups are present. These azo-compounds have excellent flame retardant properties, either if applied alone, or combined with other compounds, having flame retardant properties.
Abstract:
The invention pertains to a method of producing comb block copolymers from epoxy- functionalized nitroxylethers and further monomers by anionic polymerization followed by nitroxyl mediated controlled free radical polymerization. The block copolymer backbone has defined initiating points where radical grafting of ethylenically unsaturated monomers can take place. Further aspects of the invention are comb block copolymers obtained by this process and the use of such polymers for plastic applications.
