Water-soluble sulfonated monomers. Fong, Dodd W.; Kowalski, David J. (Nalco Chemical Co. , USA). U.S. US 4490308 A 25 Dec 1984, 8 pp. (English). (United States of America). CODEN: USXXAM.There are some reagents like 108-31-6 is used in this study. CLASS: ICM: C07C143-12. ICS: C08F028-02. NCL: 260513000N. APPLICATION: US 83-509549 30 Jun 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Polymerizable anionic monomers RR1NCOCHR2CHR3CO2M [R, R1 = H, (meth)allyl, and when one of R and R1 = H, the other = (meth)allyl; R2, R3 = H, SO3H, but R2 is not equal to R3; M = H, Li, Na, K, Mg, NH4 or Ca] are prepd. by treating maleic anhydride [108-31-6] with an amine and then treating with Na2SO3 or NaHSO3. 108-31-6 is the cas registry number of certain chemical which is used as reagents here. Thus, maleic anhydride is treated with diallylamine [124-02-7] to give N,N-diallylmaleamic acid (I) [28446-55-1], extd. with NaOH soln. to give I sodium salt [95479-94-0], and treated with NaHSO3 to give 3-carboxy-3-sulfo-N,N-diallylpropionamide sodium salt (II) [95510-81-9]. II was mixed with 2,2'-azobis(2-amidinopropane).HCl to give homopolymer [92468-83-2] having av. mol. wt. 16,400 and dispersity factor 2.2. ..

Hydrophobically associating ionic copolymers of methyldiallyl(1,1-dihydropentadecafluorooctoxyethyl)ammonium chloride. Gopalkrishnan, Sridhar; Butler, George B.; Hogen-Esch, Thieo E.; Zhang, Nai Zheng (Cent. Macromol. Sci. Eng., Univ. Florida, Gainesville, FL 32611-2046, USA). ACS Symp. Ser.Several reagents with their cas registry numbers 92265-57-1 and 124-02-7 are used here., 467(Water-Soluble Polym.), 175-88 (English) 1991. CODEN: ACSMC8. ISSN: 0097-6156. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Copolymers of diallyldimethylammonium chloride (I) with diallyldecylmethylammonium chloride (II) and methyldiallyl(1,1-dihydropentadecafluorooctoxyethyl)ammonium chloride (III) were prepd. and rheol. properties of the copolymers were investigated. At the same concn., the viscosity of I-II and I-III copolymers was higher than that for poly-I. Increased hydrophobicity of III copolymers due to the presence of the perfluoro group is reflected in significantly enhanced viscosities above the overlap concn. (at a particular comonomer content). All copolymers exhibited increased viscosities in saline soln. I-II copolymer exhibited Newtonian behavior whereas I-III copolymer exhibited non-Newtonian pseudoplastic behavior. .
