Synthesis and characterization of model comb-branched polyurethanes

Synthesis and characterization of model comb-branched polyurethanes. Bezwada, R. S.; Stivala, S. S. (Chem. Res. Div., Am. Cyanamid Co., Bound Brook, NJ 08805, USA). Polym. Prepr. (Am. Chem. Soc., Div. Polym. Chem.), 23(1), 278-9 (English) 1982. CODEN: ACPPAY. ISSN: 0032-3934. 4202-38-4 and 115-69-5 which are cas registry numbers of substances are two of reagents here. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) Section cross-reference(s): 35 Model comb-branched polyurethanes with identical branches attached to the main chain at regular intervals were prepd. The effect of branching on intrinsic viscosity was discussed. The branching factor of these comb-branched polyurethanes was dependent on the length of the branch, the frequency of the branching, and the no. of branches. .

Thickening compositions for water-based functional fluids and water-based functional fluids containing them

Thickening compositions for water-based functional fluids and water-based functional fluids containing them. Hentschel, Karl Heinz; Rasp, Christian; Kussi, Siegfried; Hendricks, Udo Winfried (Bayer A.Some chemicals with cas registry numbers like 1943-84-6 and 4202-38-4 are also used.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3531915 A1 19 Mar 1987, 7 pp. (Germany) CODEN: GWXXBX. CLASS: ICM: C10M119-24. ICS: C10M119-16; C10M173-00. APPLICATION: DE 85-3531915 7 Sep 1985. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Thickener compns. for water-based functional fluids (e.g., hydraulic fluids) contain 0.1-3 wt.% surfactant and 1 wt.% water-sol. capped polyetherpolyols, in which >50% of the hydroxy end groups are capped with long-chain aliph. monoisocyanates. A formulated water-based functional fluid, contg. 5 wt.% isocyanate-terminated polyetherpolyol [prepd. by reaction of ethylene oxide-propylene oxide copolymer ether with pentaerythritol (av. mol. wt. 22,400) with dodecylisocyanate] and 2 wt.% surfactant [ethoxylated (d.p.19) oleyl alc.], had a viscosity of 70.7 mm2/s. .
