<p>The instant invention pertains to novel fluorosilicone polymers that have a very low surface tension, excellent oil resistance, excellent heat resistance, and so forth. The fluorosilicone polymers of this invention are comprised of siloxane units of the following formula [F(CF2)aC2H4]2SiO2/2 (a), where a is an integer with a value of 1 to 10, or of the formula {[F(CF2)aC2H4]2SiO2/2}x(R2SiO2/2)y (c), wherein a is an integer with a value of 1 to 10, x is an integer with a value of at least 2, y is an integer with a value of at least 1, x > y, and R is a monovalent hydrocarbon group.</p> |
