HEAT RECOVERABLE POLYMERIC ARTICLES |
| 摘要 |
<p>HEAT RECOVERABLE POLYMERIC ARTICLES Ramsey/Rowlands/Schott/Siden Heat recoverable articles prepared from semicrystalline polymers having a glass transition temperatures, Tg, above about 25.degree.C exhibit unexpectedly high recovery stress under certain conditions. A preferred method of preparing such a heat recoverable article comprises heating the article above its glass transition temperature, Tg, deforming the article while it is above Tg but below the crystalline melting temperature, Tm, and cooling the article to a temperature below Tg while maintaining it in the deformed state.</p> |
