Abstract: Thermoplastic vulcanizates are prepared by curing, at least partially by dynamic vulcanization, blends of chlorinated polyethylene and crystalline thermoplastic polymers such as polypropylene. Inclusion of a plasticizing material or extender oil, e.g. trioctyl trimellitate, enhances softness and oil resistance of the blends. Vulcanizing materials include a basic material, normally added with the chlorinated polyethylene, and (1) a derivative of 2,5-dimercapto-1,3, 4-thiadiazole or (2) a combination of 2,5-dimercapto-1,3,4-thiadiazole and an activator material such as an amine having a boiling point of 110.degree. C. or higher and a pk value less than 4.5.

Abstract: This invention relates to a process for preparing compounds of the formula,N.sub.3 P.sub.3 (R.sub.1).sub.n (R.sub.2).sub.6-nwherein R.sub.1 is an aminophenoxide; R.sub.2 has up to 6 carbon atoms and is an alkoxy, an alkenoxy, a fluoro-substituted alkoxy, a fluoro-substituted alkenoxy or an aryloxy radical; and n is a whole integer .gtoreq.1 and .ltoreq.6. The process comprises reacting a chlorocyclotriphosphazene with an R.sub.1 salt to form an R.sub.1 -chlorocyclotriphosphazene which is further reacted with an R.sub.2 salt.Novel compounds of the formula,N.sub.3 P.sub.3 (R.sub.1).sub.n Cl.sub.6-nare also disclosed.

Abstract: A method for the rapid rendering of transparent polymer articles astatic by treating the articles with dilute gaseous sulfur trioxide followed by treatment with base such as ammonia and water or dilute aqueous ammonia. The articles are rendered permanently astatic without affecting their transparency by this process.

Abstract: Pigmented detergents having improved shelf stability are provided by dispersing in liquid detergent a polymeric pigment made by an emulsion polymerization process comprising the steps of (1) emulsion polymerizing from about 0 to about 80 weight percent of total monomer in absence of emulsifier, (2) adding a nonionic surfactant, and (3) continuing emulsion polymerization of the remaining monomer charge.
