    • The process enables highly effective N-halogenation of a compound having one or more halogenatable amido or imido functional groups in the molecule. The process involves, for example, concurrently feeding into a reactor (i) water, inorganic base, and the compound to be N-halogenated, e.g., a hydantoin, and a feed of (ii) a brominating agent and/or a chlorinating agent. The proportions of these feeds are such that the pH is kept at 5 or below or within a specified range e . g ., 5.5-8.5 and one or more of the amido or imido nitrogen atoms is substituted by a bromine or chlorine atom. A feature of the process is that it can be conducted at elevated temperatures as high as about 90°C without appreciable thermal decomposition of reactants or product. The resultant product continuously precipitates in high yield and purity. Moreover, products can be produced that are very pale yellow to almost pure white in appearance. Further, the process has been found capable of producing 1,3-dibromo-5,5-dimethylhydantoin with far larger particle sizes than previously produced on a commercial basis.

    • The invention is directed to pellets of unadulterated brominated anionic styrenic polymer having the following characteristics: A) a bromine content of at least about 50 wt%; B) an average crush strength in the Crush Strength Test of at least about 28 pounds per square inch; C) a particle size range in which at least about 70 wt% of the pellets are retained on a standard US No. 40 sieve and no more than about 30 wt% are retained on a standard US No. 5 sieve, which pellets can be prepared by brominating at least one anionic styrenic polymer having a GPC weight average molecular weight (Mw) in the range of about 2000 to about 200,000 and a GPC polydispersity in the range of 1 to about 2. Further, the invention is directed to pellets of unadulterated brominated styrenic polymer wherein the unadulterated brominated styrenic polymer is prepared by brominating at least one free-radically produced styrenic polymer having a GPC weight average molecular weight (Mw) in the range of about 30,000 to about 500,000 and a GPC polydispersity in the range of 1 to about 10, and wherein the brominated styrenic polymer formed in said process has a bromine content of at least about 50 wt%.
