(57) [Abstract] [Purpose] To provide a novel fluorosilicone polymer having low surface tension, oil resistance, heat resistance and the like. [Structure] Formula (a): [F (CF 2 ) aC 2 H 4 ] 2 SiO 2/2 (In the formula, a is an integer of 1 or more and 10 or less.) A fluorosilicone polymer composed of a siloxane unit. And formula (c): {[F (CF 2 ) aC 2 H 4 ] 2 Si O 2/2 ]} x (R 2 SiO 2/2 ) y (where a is 1 or more and 1 It is an integer of 0 or less, x is an integer of 2 or more, y is an integer of 1 or more, x> y, and R is a monovalent hydrocarbon group. ) A fluorosilicone polymer represented by: |
