HYPERBRANCHED POLYMERS CONTAINING POLYHEDRAL OLIGOSILSESQUIOXANE BRANCHING UNITS

摘要

The HBP Free-POSS compounds of Formula I are superior to prior HB polymers and linear polymers in space and electronic applications because they have better resistance to electrons, protons and atomic oxygen, have superior out-gassing performance, and are transparent. They are used as coatings, films, adhesives, sealants and elastomers.
