    • A process for the production and treatment of a stereoregular polypropylene, such as isotactic polypropylene in which a polymerization reactor is operated under conditions to react propylene supplied to the reactor to produce a stereoregular propylene polymer fluff. A product stream containing the fluff and unreacted propylene is withdrawn from the reactor and at least a portion of the unreacted propylene is separated from the product stream. The propylene polymer fluff is heated to a temperature sufficient to melt the propylene polymer, and a lactone is incorporated into the propylene polymer. The lactone is a 5,7 dialkyl-3-(2,3 dialkyl phenyl)-3H-benzofuran-2-one, in which the 5,7 and 2,3 substituents are of relatively low molecular weights. The phenyl alkyl substituents, each contain 1 or 2 carbon atoms, and the 5,7 alkyl substituents each contain from 2 to 5 carbon atoms. After the heating and incorporation of the lactone, the heated polymer fluff containing the lactone is extruded to produce particles of the propylene polymer. The polymer particles containing the lactone can be heated to a molten state and then extruded to form a fiber preform. The fiber preform is subject to spinning and drawing at differential spinning and drawing speeds to provide a draw ratio sufficient to form a continuous polypropylene fiber.
    • 一种制备和处理立体规则聚丙烯的方法,例如全同立构聚丙烯,其中聚合反应器在提供给反应器的丙烯反应产生立体规则丙烯聚合物绒毛的条件下运行。 将含有绒毛和未反应的丙烯的产物流从反应器中排出,至少一部分未反应的丙烯与产物流分离。 将丙烯聚合物绒毛加热至足以熔化丙烯聚合物的温度,并将内酯加入到丙烯聚合物中。 内酯是5,7-二烷基-3-(2,3-二烷基苯基)-3H-苯并呋喃-2-酮,其中5,7和2,3个取代基具有相对​​较低的分子量。 苯基烷基取代基各自含有1或2个碳原子,5,7个烷基取代基各自含有2至5个碳原子。 加热并加入内酯后,将含有内酯的加热聚合物绒毛挤出以产生丙烯聚合物的颗粒。 可以将含有内酯的聚合物颗粒加热至熔融状态,然后挤出以形成纤维预制件。 在不同的纺丝和拉伸速度下对纤维预制件进行纺丝和拉伸,以提供足以形成连续聚丙烯纤维的拉伸比。
