(English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: A61L015-07. ICA: C08G018-20. APPLICATION: EP 83-300646 9 Feb 1983. PRIORITY: US 82-347596 10 Feb 1982. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) A storage-stable orthopedic cast bandage comprises a water-activatable polyurethane prepolymer, prepd. from an arom. polyisocyanate and a polyol and dimorpholinodiethyl ether (I) [6425-39-4] catalyst, coated on an open-weave fibrous substrate. I provides long gel times and short set times. In prepn.There are some commonly used reagents with their cas registry numbers 6425-39-4 and 88504-43-2 in this article. of a series of polyurethane prepolymers, I gave superior properties to a no. of other catalysts tested. A prepolymer was prepd. from Isonate 143L, Pluracol P1010, and Poly G 36-232 using BzCl, Dow corning DC-200 antifoam agent, and I catalyst. The gel time of the prepolymer at 70° was 33 days and the set time of a bandage made with this prepolymer on polyester/cotton fabric was ~4.7 min. .

Sound-insulating adhesive for laminates based on a polyurethane prepolymer. (Bostik Findley GmbH, Germany). Ger. 697765-47-2 and 6425-39-4 are also occured in this study. Gebrauchsmusterschrift DE 202004015265 U1 13 Jan 2005, 5 pp. (German). (Germany). CODEN: GGXXFR. CLASS: ICM: E04F015-20. ICS: C09J175-08. APPLICATION: DE 2004-202004015265 29 Sep 2004. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) For fixing of laminate floor coverings a one-component polyurethane prepolymer based on crude MDI and a polyether polyol from polypropylene glycol ether and ethylene oxide is directly applied on the ground and cures by the penetrating humidity from the ground. The adhesive comprises furthermore 0.1-1.5 wt.% 2,2'-dimorpholino-diethyl ether as catalyst, as well as 5-10 wt.% diisononyl phthalate as plasticizer and/or 0.1-0.5 wt.% polyether-polydimethylsiloxane as foam stabilizer (each referred to the polyurethane prepolymer). .
