Abstract
The present invention relates to hyperbranched copolymer networks containing hyperbranched copolymers that have perfluorocarbon and organosilicon entities that have high hydrophobicity, or high oleophobicity, or high thermal stability, or good adhesion to substrates, or any combinations thereof. This invention provides a further desirable combination of properties that include solubility before crosslinking, chemical resistance, and easy processibility. The copolymers may be crosslinked with a variety of crosslinking agents to give either rigid or elastomeric networks.
