Haloaldehyde polymers: Haloaldehyde polymers. IX. Poly(bromodichloroacetaldehyde). Lipp, D. W.; Vogl, O. (Univ. Massachusetts, Amherst, Mass., USA). J. Polym. 34619-29-9 which is the cas registry number of some chemical is mentioned. Sci., Polym. Chem. Ed., 16(6), 1311-33 (English) 1978. CODEN: JPLCAT.Except for chemicals metioned above, 34619-29-9 is also used. ISSN: 0449-296X. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 23 CBrCl2CHO (I) [34619-29-9] was homopolymd. at -30° by anionic and also some cationic initiators to a polymer [64316-13-8] which was insol. and did not melt but degraded to monomer at >200°; the ceiling temp. of the polymn. was -15° in 1M soln. I was also copolymd. with isocyanates, primarily aryl isocyanates, and also with chloral (II) [75-87-6]. I was prepd. by 2 methods (a) II was treated with Ph3P and the resultant compd. was brominated and hydrolyzed to give I (60% yield), and (b) bromination of dichloroacetaldehyde di-Et acetal [619-33-0] at 100° (20-30% yield). ..
