Preparation of polyurea-polyurethane gel for air fresheners

Preparation of polyurea-polyurethane gel for air fresheners. (Uni-Charm Corp., Japan). Jpn. Kokai Tokkyo Koho JP 59057658 A2 3 Apr 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A61L009-01. APPLICATION: JP 82-167623 28 Sep 1982. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Air fresheners comprise hydrophilic urethane prepolymer 5-50%, odorless solvent 5-50% by wt. plus a fragrant soln. These air fresheners can be readily prepd. and the viscosity of the urethane prepolymers is decreased by the solvents, and the mixing process is improved. Thus, polyethylene polypropylene ethylene glycol ether [53637-72-2] and polyethylene polypropylene glyceryl ether [9082-00-2] were treated with toluylene diisocyanate to obtain a urethane prepolymer (viscosity 8000 cP at 25°). Treatment of this polymer with diethylene glycol monoethyl ether acetate [112-15-2] decreased the viscosity to 700 c P at 25°. Finally, this product was combined with an orange oil, a nonionic surfactant, Nonipol-120, iso-PrOH, 2,6-di-tert-butylhydroxytoluene, and H2O to give an air freshener.

Stable dispersions of polymers in polyfunctional compounds having a plurality of active hydrogens. Fisk, Thomas E. (Dow Chemical Co., USA). U.S. US 4493908 A 15 Jan 1985, 8 pp. Cont.-in-part of U.S. Ser. No. 467,409. (English). (United States of America). CODEN: USXXAM. CLASS: ICM: C08G018-10. ICS: C08L075-00. NCL: 521137000. APPLICATION: US 84-581405 17 Feb 1984. PRIORITY: US 83-467409 17 Feb 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 37 Dispersions useful in the prodn. of polyurethane foams are prepd. by polymg. dispersions of unsatd. derivs. of glyoxyloyl chloride and vinyl compds. in polyfunctional active H compds., e.g. polyether polyols. Thus, the reaction of 0.038 mol 1:1 oxalyl chloride-2-hydroxyethyl methacrylate adduct with 0.035 mol (100 g) polypropylene glycol mono-Bu ether in CH2Cl2 contg. 0.038 mol Et3N gave an unsatd. ester [96190-45-3]. Stirring 35.2 g this adduct in 510 g glycerol polyethylene-polypropylene glycol ether (1:3) [9082-00-2] at 120° while adding 2.7 g AIBN in 134 g styrene over 90 min and stripping at 120°/15 mm for 2 h gave a copolymer [96190-50-0] dispersion with viscosity 1900 cP at 25°.
