  • Method for improving impact strength in high nitrile polymers by stretching and heat setting
    Patent number: 4006211
    Abstract: High nitrile polymer articles having improved impact strength and dimensional stability are prepared by stretching in more than one direction a solvent-free, thermoformed polymer article having less than 0.5 percent water and then heat setting the oriented article while in a restrained position at orientation temperatures for about 5 seconds to 2.5 minutes.
