Abstract: Mixtures which can be cross-linked by photopolymerization and are based on soluble elastomeric block copolymers, photopolymerizable monomers which are compatible with these, photoinitiators and plasticizers contain, as the plasticizer, a chloroalkane of 8 to 40 carbon atoms which has a chlorine content of from 30 to 73% by weight.

Abstract: Compounds having defined functional groups are described which color stabilize aromatic carbonate polymers or blends therewith upon exposure to sterilizing radiation.

Abstract: Polymeric compositions are provided in which perfluoropolyethers have been solubilized in non-fluorinated solvents by combining them with a solubilizing agent such as azotic conjugated compounds, and phosphorylated compounds. Typical of the perfluoropolyethers is ##STR1## Typical of the solubilizing agent is phosphorylated methacryloyloxyhydroxypropylisophthalate. The perfluoropolyether and the solubilizing agent are mixed to form a paste which is soluble in organic solvents such as methylethylketone. These compositions find utility as protective lubricant coatings for thin film magnetic recording media. They have the advantage that only one coating step is required in order to apply both the phosphorylated compound and the lubricating polyether. Recording media lubricated with these compositions have demonstrated excellent wear characteristics.

Abstract: The specification describes a composition curable by high-energy radiation in the presence of oxygen which contains conventional monomers, oligomers and/or polymers curable by high-energy radiation besides minor amounts of a natural wax, a solvent extraction product of a natural wax, a wax alcohol, a wax ester and/or a wax carboxylic acid. The specification also describes the preparation of said composition and the use thereof in the formation of coatings.
