Description

ABSTRACT:
This invention concerns polymers, having fluoroalkoxy side chains, which are made by a novel process comprising reacting a polymer containing hydroxyl groups, especially poly(vinyl alcohol), with a fluorinated olefin in the presence of a base. The resulting polymers are useful in coatings, as in optical wave guides, and antireflective coatings and in other optical devices.
