The Interaction of Liquid Environments with Hard Elastic High Impact Polystyrene
The hard-elastic behavior exhibited by specially prepared polymers has been under intensive investigation since its patenting in the mid-1960’s . Recently, the phenomenology of hard elasticity in crystalline polymers has been thoroughly reviewed by Sprague  and more recently, Cannon, McKenna and Statton . Common mechanical and physical properties of these unique materials include (a) an initial Hookean elasticity, (b) high recoverability from large strains, (c) energetic retractive forces, (d) rehealing after work softening, and (e) constant cross-sectional area during deformation.
