All three polymers are highly water repellent. HBPF and CF 3 O-HBPF show very similar hydrophobicity. Conclusion HBPF has been synthesized in good yield by simple synthetic procedures. The molecular weight can be easily varied. Two derivatives have been synthesized, although the yields still need to be optimized.
All polymers are highly soluble in organic solvents and highly hydrophobic.
Potential uses for these materials include lubricants and coatings in applications that require minimally-adhesive materials. The functionality of the chain ends can be easily modified to adapt the physical and chemical properties of the hyperbranched materials to the application in question. Ardoin, N. and Astruc, D.
