Konf., 3rd, Meeting Date 1974, 174-5. Edited by: Kuz'mitskii, B. B. Beloruss. Med. O-vo. Farmakol. Toksikol.: Minsk, USSR. (Russian) 1975. CODEN: 35ALA9. DOCUMENT TYPE: Conference CA Section: 4 (Toxicology) Gas-liq. chromatog. showed that EtBr [74-96-4], PrBr [106-94-5], BuBr [109-65-9], iso-BuBr [78-77-3], and isoamyl bromide [107-82-4] administered orally to rats at LD50 were deposited mainy in the brain, liver, and perirenal cellular system and excreted primarily by the lungs.

Study of the haloalkylation of poly(4-vinylpyridine)

Study of the haloalkylation of poly(4-vinylpyridine). Korshak, V. V.; Zubakova, L. B.; Zhovnirovskaya, A. B.; Kuz'menko, N. E. (Mosk. Khim.-Tekhnol. Inst. im. Mendeleeva, Moscow, USSR). Vysokomol. Soedin., Ser. B, 19(6), 428-30 (Russian) 1977. CODEN: VYSBAI. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Poly(4-vinylpyridine) (I) [25232-41-1] was prepd. by continuous polymn. in aq. H2SO4 and neutralization of the resulting salt with NaOH. Alkylation of I with EtBr [74-96-4], EtI [75-03-6], oe PrBr [106-94-5] gave the corresponding quaternary polymers of degree of substitution 28-48% in 35-68% yields. The degrees of substitution and the yields of quaternary polymers decreased on passing from EtBr to PrBr and from EtI to EtBr. The optimum conditions for prepn. of I and for its alkylation were given.
