The present invention relates to the use of phosphorous-containing organic oxyimides according to the general formula (I) as flame retardant for plastic materials, as radical generators in plastic materials and/or stabilisers for plastics. In addition, the present invention relates to a flame-retardant plastic material moulding compound in which the previously described phosphorous-containing organic oxyimides are integrated, and also to a method for the production of the previously mentioned plastic material composition. Furthermore, the present invention relates to a moulded article, a paint or a coating from the previously mentioned flame-retardant plastic material composition.

The invention relates to the use of organic oxyimide salts as flame retardants for plastics and to a corresponding flame retardant plastic composition. The invention also relates to a method for producing said type of plastic composition or a moulded part produced therefrom, a moulding compound, a moulded part, paint or a coating.

Embodiments of organic peroxide formulations provide significant improvements in surface tackiness (often including tack-free surfaces) when curing elastomers in the presence of oxygen. The peroxide formulations may include, for example, one or more compounds selected from sulfur-containing compounds, organophosphite compounds, HALS (Hindered Amine Light Stabilizer) compounds, aliphatic allyl urethane compounds, and blends comprising nitroxides (e.g., 4-hydroxy-TEMPO) and quinones (e.g., mono-tert-butylhydroquinone).

The invention relates to a separating film based on polyolefins or ethylene copolymers with a content of organic and optionally inorganic pigment and at least one UV stabilizer. The separating film has a transmission percentage between 5 and 20% in the range from 400 to 700 nm and a transmission percentage of <2% in the range from 300 to 500 nm. Such separating films have the advantage that marking regions applied onto membranes which can be found below the separating film remain detectable, and adhesives which can be found below the separating film are effectively protected from UV light and premature aging by the addition of inorganic and organic pigments and UV stabilizers. The invention further relates to composite structures of corresponding separating films and adhesives, to water-tight membranes with coatings made of adhesive and separating films, and to uses of corresponding membranes for sealing structures against water.

A composition includes a polymer, a functional component, and an oxidation catalyst. The functional component may be an oxidizable additive or a precursor thereof. The oxidizable additive includes an organic moiety including a first carbon atom (C1) attached to a hydrogen (H), a first group having a conjugated unit (a double bond, a triple bond, an aromatic ring); a second group having a heteroatom (including C═N, N═O, C═O, an O, a N, a fragment having at least three heteroatoms (including a N) within a spatial distance of 4 Å from C1); and a third group (hydrogen, an alkyl group, an aromatic group, a double bond, a triple bond, and a heteroatom). The C1 may be attached to a strong mesomeric electron-donating group and a strong mesomeric electron-withdrawing group; or to a conjugated group and a mesomeric group. The functional component may be derived from a recycled plastic article.
