| 1 | STUDIES ON THE NATURE OF THE MACROMOLECULAR CONDENSED STATE OF 'NASCENT' ULTRA HIGH MOLAR MASS POLYETHYLENE显示文摘Ultra high molar mass polyethylene (UITPE) powder as polymerized in a slurry process has been studied, in its nascent state, after recrystallization on rapid cooling from the melt and after hot compression molding to a film, by DSC,effect ofannealing the recrystallized specimen at 120~I30℃, morphology by polarizing optical microscopy and small angle X-ray scattering. Based on the experimental results obtained the macromolecular condensed state of the nascent UHPE powder is a rare case of a multi-chain condensed state of non-interpenetrating chains, involving interlaced extended chain crystalline layers and relaxed parallel chain amorphous layers. On melting, a nematic rubbery state of nanometer size domain resulted. The nematic-isotropic transition temperature was judged from literature data to be at least 220°C, possibly higher than 300 °C, the exact temperature is however not sure because of chain degradation at such high temperatures. The recrystallization process from the melt is a crystallization from a nematic rubbery state. The drop of remelting peak temperature by 10 K of the specimen recrystallized from its melt as compared to the nascent state has its origin in the decrease both of the crystalline chain stem length and of the degree of crystallinity. The remelting peak temperature could be returned close to that of the nascent state by annealing at 120~130°C. | Zhong-yong Fan Qiang Lan Hai-shah Bu Li-heng Wu Lin Sun Ren-yuan Qian Shou-xi Chenc Yong-feng Mend Bing-zheng Jiang | 2001 | Chinese Journal of Polymer Science2001，19，1： | 2 |
