Cushions for dynamic impact applications include anisotropic cellular polymers made in an extrusion, expanded bead or reactive foaming process. The anisotropic behavior represented by C/C, C/Cand C/C, wherein C, Cand Crepresent the compressive strength of the cellular polymer in each of three orthogonal directions E, V and H, respectively, as measured by compressing a 25-50 mm thick sample of the cellular polymer at a strain rate of 0.08 sto 25% strain, Crepresents the sum of C, Cand C, and at least one of C/C, C/Cand C/Chas a value of at least 0.40, up to about 0.80. The cellular polymer also preferably has density of 1.75 to 2.35 pounds/cubic foot and a compressive stress in the direction of maximum compressive strength of 290-600 kPa at 25% strain when used for headliner countermeasure applications. The cushions are useful in automotive applications such as automotive headliners, door panels, knee bolsters, pillars, headrests, seat backs, load floors or instrument panels.

Olefinic polymer compositions

The present invention is directed to a composition comprising a hydrogenated block copolymer of a vinyl aromatic and conjugated diene polymer, having a lamellar morphology and high aromatic hydrogenation level.

Hydrogenated block copolymer compositions

Oriented, syndiotactic, optically transparent vinylaromatic polymers are prepared by a process comprising heating the polymer to a temperature above its crystalline melting point, cooling the polymer to a temperature less than an orientable temperature at a rate sufficient to avoid substantial crystal formation, and inducing strain into the polymer while at a orientable temperature to induce crystal formation and molecular orientation.
