Embodiment 1
[0041] (1) After evacuating the self-made polymerization bottle for 1-2 hours, add PHMS (3g, 1.67mmol), 40%-80% THF, PEO (0.7g, 1.67mmol), AGE (0.23g, 1.67mmol) and Karstedt's The catalyst (20μl) was bubbled with nitrogen for 15-20min, and the temperature was raised to 60°C for 3-4h, then the temperature was lowered to 45°C and PFBE (1.968g, 6.68mmol) was added, the temperature was raised to 58°C, and hydrosilylation was carried out for 10-12h reaction.
[0042] (2) Pour out the polymer solution after cooling, distill under reduced pressure at 40°C to remove impurities such as small molecules and by-products, and dry in a vacuum oven for 24 hours.
[0043] For products 1 HNMR and FTIR characterize the structure of the polymer, specifically as figure 1 and figure 2 shown.
