Abstract
The present invention relates to polymeric microspheres comprised of short-chain diol diacrylate homopolymers or copolymers of diol diacrylates and long-chain acrylate esters, which exhibit excellent antifriction characteristics when applied on the surface of plastic sheets. Treated sheets exhibit a significantly lower coefficient of friction than sheets treated with commercially-available microspheres.
