Abstract: A photodegradable polymer composition comprising 50 to 99 weight percent based on the total weight of photodegradable polymer composition of a thermoplastic addition polymer and 1 to 50 weight percent based on the total weight of the photodegradable polymer composition of a photodegrading agent, said photodegrading agent being a polyketone which is a linear copolymer consisting of units of --CO(C.sub.2 H.sub.4)-- and units --CO(B')-- where B' is derived from olefinically unsaturated hydrocarbon selected from the group consisting of CHR.sub.4 .dbd.CHR.sub.5 (I) and CH.sub.2 .dbd.C(R.sub.6)(CHR.sub.7 R.sub.8) (II), wherein R.sub.4 is a hydrocarbyl group, R.sub.5 is hydrogen or a hydrocarbyl group, R.sub.6 is a hydrocarbyl group, and R.sub.7 and R.sub.8 are individually hydrogen or hydrocarbyl groups.

Abstract: A flame retardant polymer composition which is substantially free of halogen compounds and of organometallic salts comprises (A) an organic polymer, at least 40% by weight of which is a copolymer of ethylene with one or more comonomers selected from the group consisting of alkyl acrylates, alkyl methacrylates, acrylic acid, methacrylic acid and vinyl acetate, (B) a silicone fluid or gum and (C) an inorganic filler which is a compound of a metal of Group II A of the Periodic Table of Elements but which is neither a hydroxide nor a substantially hydrated compound. Suitable inorganic fillers are magnesium oxide, magnesium carbonate and calcium carbonate, the latter being the most preferred. The compositions are particularly suitable for use in wire and cable applications.

Abstract: An original container-applicator device for relatively viscous preparations, such as and of the consistency of hair shampoos and conditioners. Provided with a supply of such a preparation, the device functions as the original container until, in the hands of the ultimate consumer, it serves also as the applicator. The device comprises a chamber; massage fingers, an outlet or dispensing port, as defined by an elongate rim with a proximal end and a distal end; and, a reciprocative valve. The valve has a flange and a gate, and moves between first and second positions. At the first position, the gate closes the distal end while the valve leaves the proximal end open and enables the preparation from the chamber to fill the rim, but not flow from the device. At the second position the flange closes the proximal end and prevents flow from the chamber, while the gate is displaced from and leaves the distal end open, thus to enable a quantity of preparation to flow or drain from the rim, and be dispensed.

Abstract: A process is disclosed for dyeing a bundle of dry-spun acrylonitrile polymer filaments before the solvent remaining after the spinning step has been extracted. The filaments having a water content of not over 30%, are subjected to a dye bath, and drawn while immersed in the bath at least 1.5.times. and are then washed to rinse them and to extract spinning solvent.
