Notes:
The stress-strain properties of oriented polymers are measured parallel and perpendicular to the direction of hot stretching. The polymers include styrene-acrylonitrile copolymers, vinyl alcohol copolymers, acrylic acid copolymers, polyelecf trolytes, and a high density polyethylene. Polarity and hydrogen bonding tend to increase the strength, especially in the direction perpendicular to the direction of hot stretching. Strong electrostatic bonding in polyelectrolytes and too much polar bonding in styrene-acrylonitrile & polymers decrease the strength by reducing the molecular mobility, which is required to prevent brittleness.
