Diorganopolysiloxane containing fluoroalkyl groups: Diorganopolysiloxane containing fluoroalkyl groups. Kaufmann, Rudolf; Braunsperger, Karl; Wegehaupt, Karl Heinrich; Von Au, Guenter (Wacker-Chemie G.m.b.H. , Fed. Rep. Ger.). Ger. Offen. DE 3248546 A1 5 Jul 1984, 13 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08G077-38. APPLICATION: DE 82-3248546 29 Dec 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Fluoroalkyl siloxanes are prepd. with min. cyclization by hydrolyzing (fluoroalkyl)dichlorosilanes and equilibrating the hydrolyzates in the presence of quaternary ammonium hydroxides. 92417-47-5 is the cas registry number of certain chemical which is used as reagents here. Thus, adding 922 g C6F13CH2CH2SiMeCl2 [73609-36-6] over 2 h to 1.18 kg 15% NaOH with stirring and stirring 15 min gave 748 g hydrolyzate with n25 1.3420 and viscosity 520 mPa-s. Kneading a mixt. of this product 162.4, OH-terminated di-Me siloxane (viscosity 100 mPa-s) 65, di-Me siloxane (d.p. 7) 10, and PhCH2NMe3+ OH- [100-85-6] (as a 40% MeOH soln.) 0.125 g at 100° for 10 min, 100°/3 mm for 2 h, 150°/1 atm for 30 min, and 150°/12 mm for devolatilization gave 225 g clear oil with n25 1.3628 and viscosity 1044 mPa-s. .

Von Au, Guenter; Innertsberger, Ernst; Schmidlkofer, Jakob; Kaiser, Wolfgang (Wacker-Chemie G.m.b.H. , Fed. Rep. Ger.). Ger. Offen. DE 3248535 A1 12 Jul 1984, 21 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07F007-18; B01D019-04; C10M003-44; C10M007-48; D06M015-66. APPLICATION: DE 82-3248535 29 Dec 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Siloxanes contg. 5-90 mol% units bearing (fluoroalkoxy)alkyl groups and 0-60 mol% units bearing fluoroalkyl groups are useful as lubricants and antifoaming agents. Thus, adding C6F13CH2CH2Si(Me)Cl2 [73609-36-6] 115, HCF2CF2O(CH2)3Si(Me)Cl2 [1692-54-2] 136.5, and Me2SiCl2 64.5 g over 1 h to 687 g 15% NaOH stirred at ￡80° and stirring 15 min gave 216 g OH-terminated siloxane with viscosity 170 mm2/s. Heating 217 g this siloxane, 9 g di-Me siloxane (d.p. 10), and 0.136 mL 25% CH2Cl2 soln. of poly(dichlorophosphazene) at 100°/1 mm for 3 h, adding 0.271 mL triisononylamine, and stripping at 130°/1 mm gave 95% clear oil with viscosity 5000 mm2/s and nD20 1.3730, contg. di-Me units 40, fluoroalkyl units 20, and (fluoroalkoxy)alkyl units 40 mol%.
