Patent ID: 8231973

Claim:
A low refractive index polymerizable organic composition comprising A) at least 5 wt-% of a free-radically polymerizable fluorinated polymer dissolved or dispersed in an organic solvent wherein the fluorinated polymer comprises the reaction product of i) at least one multi-functional free-radically polymerizable material having a fluorine content of at least about 25 wt-%, and ii) optionally at least one multi-functional free-radically polymerizable material having a fluorine content ranging from 0 to less than 25 wt-%, wherein the total amount of multi-functional free-radically polymerizable material is at least 60 wt-% based on wt-% solids, wherein the fluorinated polymer comprising comprises polymeric species having a hyperbranched structure; and B) at least one fluorinated free-radically polymerizable material.
