| 摘要 |
<p>The invention relates to a method for the preparation of a reinforced polymer composition which contains fibrils of a crystalline polyolefin having a weight-average molecular weight (Mw) of at least 5 x 105 kg/kmol, particles of the crystalline polyolefin being converted into fibrils in a matrix material which is immiscible with the crystalline polyolefin, in which method the crystalline polyolefin has a maximum stretch ratio of at least 20 and the conversion to fibrils takes place at a temperature below the melting point of the crystalline polyolefin. The invention also relates to reinforced polymer compositions obtainable by this method.</p> |
