| titleOfInvention | Process for producing controlled viscosity fluorosilicone polymers |
| abstract | A process for making a fluorosiliconen nMD a D F b M′n nwheren M=R 1 R 2 R 3 SiO 1/2 ; M′=(OH)R 6 R 7 SiO 1/2 or (OH)R 4 R 5 SiO 1/2 ; D=R 4 R 5 SiO 2/2 ; and D F =R 6 R 7 SiO 2/2 ;n nwhere the subscript a is zero or positive, the subscript b is positive and the subscripts a and b satisfy the following relationship: b>0.4(a+b) and R 1 is selected from the group of 1 to 20 carbon atom monovalent alkyl, aryl, or alkaryl hydrocarbon radicals and terminally unsaturated alkenyl groups of from 2 to 10 carbon atoms; R 2 , R 3 are each independently any monovalent hydrocarbon radical: alkyl, aryl, or alkaryl of from 1 to 20 carbon atoms or R 1 and each R 4 and R 5 are any monovalent hydrocarbon radical: alkyl, aryl, alkenyl, or alkaryl of from 1 to 20 carbon atoms, and R 6 is a fluorine substituted 3 to 20 carbon atom monovalent hydrocarbon radical having no fluorine substitution on the alpha or beta carbon atoms of the radical and R 7 is any monovalent hydrocarbon radical: alkyl, aryl, or alkaryl of from 1 to 20 carbon atoms or R 6 by reactingn 1) b moles of (R 6 R 7 SiO) 3 ,n nwithn 2) a moles of (R 4 R 5 SiO) 3 , 3) R 1 R 2 R 3 SiOH and 4) an oxygenated promoter. Compositions made by the process and articles of manufacture made from the compositions. |
