Abstract
(EN)
Provided is a method for preparing a high-performance ultra-high molecular weight polyethylene resin. An ethylene monomer is subjected to a polymerization reaction by means of a single active site-loaded polyethylene catalyst in a reactor to prepare a polyethylene resin having a lower entanglement degree and a narrower molecular weight distribution. Compared with the prior art, the polyethylene raw material obtained by means of polymerization has the characteristic of a narrow molecular weight distribution, thereby greatly improving the mechanical properties of the resulting ultra-high molecular weight polyethylene; furthermore, the low entanglement property thereof solves the current problem that an ultra-high molecular weight polyethylene with a narrow molecular weight distribution is difficult to uniformly dissolve in a solvent.

L'invention concerne un procédé de préparation d'une résine de polyéthylène de masse moléculaire ultra-élevée haute performance. Un monomère d'éthylène est soumis à une réaction de polymérisation au moyen d'un catalyseur de polyéthylène à site actif unique dans un réacteur pour préparer une résine de polyéthylène ayant un degré d'enchevêtrement inférieur et une distribution de poids moléculaire plus étroite. Par rapport à l'état de la technique, la matière première de polyéthylène obtenue par polymérisation a la caractéristique d'une distribution étroite du poids moléculaire, ce qui permet d'améliorer considérablement les propriétés mécaniques du polyéthylène à poids moléculaire ultra élevé résultant ; en outre, la propriété d'enchevêtrement faible de celui-ci résout le problème courant selon lequel il est difficile de dissoudre uniformément dans un solvant un polyéthylène de masse moléculaire ultra-élevée ayant une distribution de poids moléculaire étroite.

提供了一种高性能超高分子量聚乙烯树脂的制备方法。在反应器内,将乙烯单体通过负载单活性中心聚乙烯催化剂通过聚合反应制备得到具有较低的缠结度及较窄的分子量分布的聚乙烯树脂。与现有技术相比,聚合得到的聚乙烯原料具有窄分子量分布的特性,大幅提高所得超高分子量聚乙烯的力学性能,同时其低缠结的特性解决了目前窄分子量分布超高分子量聚乙烯在溶剂中较难溶解均匀的问题。
