Abstract
Disclosed is a method of making a conductive polymer from a non-aromatic ethylenically unsaturated gaseous monomer comprising bombarding an inert substrate with the monomer at a velocity greater than Mach 1. This can be accomplished in a vacuum using a molecular beam. Ethylene or other suitable monomer can be mixed with an inert carrier gas such as nitrogen, helium, or argon for use in the process.

A method of making a conductive polymer from a non-aromatic ethylenically unsaturated gaseous neutral addition-polymerizable monomer, comprising bombarding an inert substrate with said monomer at a velocity greater than Mach 1 in a vacuum.
A method of forming a conductive polymeric coating on an inert substrate comprising:
- (a) mixing a non-aromatic ethylenically unsaturated gaseous hydrocarbon neutral addition-polymerizable monomer with an inert carrier gas selected from the group consisting of nitrogen, helium, argon, and mixtures thereof;
- (b) accelerating said mixture in a molecular beam to a velocity of greater than Mach 2, in a pressure less than about 10.sup.-3 torr;
- and
- (c) permitting said accelerated mixture to strike said inert substrate in the free expansion region of said molecular beam.
A method of making a polymer having a resistivity less than 10.sup.8 ohm-cm from a non-aromatic ethylenically unsaturated gaseous neutral addition-polymerizable monomer, comprising bombarding an inert substrate with said monomer at a velocity greater than Mach 1 in a vacuum.
