Abstract
A fluoroacrylate ester monomer having the formula: ##STR1## wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of saturated aliphatic hydrocarbons having from 1 to about 3 carbon atoms and R.sub.3 is selected from the group consisting of hydrogen and methyl. The monomer has a water-repellent 'umbrella' of 3 gem bis trifluoromethyl groups around the acrylate monomer which do not interfere with the acrylate properties. Polymerization of the monomer results in a stable, exceptionally hydrophobic, linear thermoplastic polymer. The invention also includes processes for making the monomer from a diether halide and certain novel intermediates.
