Polymeric nitroso dimers. Donaruma, L. G.; Dandge, D. (Dep. Chem., Polytech. Inst. New York, Brooklyn, NY 11201, USA). Polym. Prepr. (Am. Chem. Soc., Div. 89905-84-0 and 19925-16-7 are also in the experiment. Polym. Chem.), 23(2), 108-9 (English) 1982. CODEN: ACPPAY. ISSN: 0032-3934. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Bisphenol A [80-05-7] and 4,4'-dihydroxybiphenyl [92-88-6] were hydrogenated to give 4,4'-isopropylidenedicyclohexanol [80-04-6] and [bicyclohexyl]-4,4'diol [20601-38-1], which were oxidized to give 4,4'-isopropylidenedicyclohexanone [7418-16-8] and [bicyclohexyl]-4,4'-dione [23391-99-3], which were oximated to give 4,4'-isopropylidenedicyclohexane dioxime [7418-18-0] and [bicyclohexyl] 4,4'-dioxime [19925-16-7], which were treated with CF3CO3H to give 4,4'-dinitroisopropylidenedicyclohexane (I) [89905-81-7] and 4,4'-dinitro[bicyclohexyl] (II) [89905-83-9], which were polymd. to give I polymer [89905-82-8] and II polymer [89905-84-0]. .

Cycloaliphatic diglycidyl ethers. Monnier, Charles E. (Ciba-Geigy A.-G. , Switz.). Eur. Pat. Appl. EP 108720 A1 16 May 1984, 19 pp. DESIGNATED STATES: R: CH, DE, FR, GB, LI. (German). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C07D303-28; C07C043-188; C08G059-04. APPLICATION: EP 83-810499 31 Oct 1983. PRIORITY: CH 82-6414 4 Nov 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 27 Unsubstituted or alkyl-substituted diglycidyl ethers (I; R,R' = C1-4 alkyl; m, n = 0, 1, 2) for epoxy resins are prepd. from unsubstituted or alkyl-substituted diols by glycidylation with glycerin dihalohydrin or epihalohydrin or by reaction with allyl chloride or bromide and subsequently epoxidizing the diallyl ether. Thus, 185 g (2.0 mol) epichlorohydrin [20601-38-1] was added to 194. 20601-38-1 is also in the experiment.0 g (0.98 mol) 1,1'-dicyclohexyl-4,4'-diol [106-89-8] and 5.4 g SnCl4 over 1.5 h at 85°, the reaction mixt. was allowed to react for an addnl. 15 min, and then 100 g NaOH was added over 30 min. The reaction mixt. was worked up to give 249 g colorless diepoxide [91829-32-2] with epoxide content 4.69 equiv/kg and viscosity 550 mPa-s. .
