| titleOfInvention | Process for the stabilising of light sensitive polymeric organic materials and the resulting products |
| abstract | Mono- or bis-(allyloxy-, methallyloxy- or cinnamyloxy-)-4-alkoxy-benzophenones, or diallyloxy benzophenones, and the corresponding halogen and/or alkyl substituted derivatives thereof are prepared by refluxing equivalent amounts of the corresponding o-hydroxy-benzophenone and alkenyl halide in the presence of anhydrous potassium carbonate and then filtering, washing and purifying by distillation. 2-methallyloxy-4-methoxybenzophenone or 2-D 21-butenyloxy-41-phenyl-4-methoxy - benzophenone are prepared by refluxing methallyl chloride or D 2-butenyl chloride and an equivalent amount of the corresponding benzophenone in the presence of potassium carbonate and potassium iodide. By using salicylic acid esters in place of benzophenones in the methods specified above then there may be obtained 2-(allyloxy- or methallyloxy-)-4- (-phenoxy-, benzoyloxy- or methoxy)-benzoic acid esters. 1-(allyloxy-, methallyloxy- or cinnamyloxy-)-(3-alkoxy- or 4-chloro-)-xanthones may be obtained by refluxing the corresponding hydroxyxanthone and alkenyl halide in the presence of potassium carbonate and potassium iodide.ALSO:Organic, polymeric material contains as light stabilizer a compound: <FORM:0958167/C3/1> wherein X is alkoxy, alkenyloxy, cycloalkoxy, aralkoxy, aryloxy, or an aromatic radical of the benzene series which, by means of an oxygen bridge, can also form a xanthone with nucleus A; R1, R2, R3 and R4 represent H, alkyl or aryl; in the nucleus A at least the 3- or 5-position is unoccupied; and the benzene rings can contain further inert substituents. Organic, polymeric materials specified are polyvinyl chloride, polyvinylidene chloride, styrene polymers, diene polymers and copolymers, polyethylene, polypropylene, polyacrylic compounds, polymethylmethacrylate, polyacrylonitrile, polyethylene glycol terephthates, polycaprolactam, polyhexamethyleneadipamide, polyesters such as that produced from 4, 41-di-carboxydiphenylsulphone and butylene glycol, polyester resins derived from unsaturated and polyesters and styrene or methyl methacrylate. Many stabilizers are specified and those used in the examples fall within the following classes: allyloxy-, methallyloxy- or cinnamyloxy- -4- alkoxy-benzophenones; allyloxy- or methallyloxy- -benzoic-, alkylbenzoic- or methoxybenzoic-acid esters; and allyloxy-, methallyloxy- or cinnamyloxy-xanthones. The stabilized polymers find application as film or foil for packaging or covering, and as watch glasses. |
