Preparation of uniaxially oriented polyamide films by vacuum deposition polymerization
- Jiro Sakata, Midori Mochizuki
- Grew polyamide (PPTA, kevlar) films using VDP (vacuum deposition polymerization).
- Two precursors were heated in a vacuum to yield a stoichiometric polymer.
- Polymer chains were oriented with rubbing with different polymers, e.g. cotton (!)
