摘要： Polypropylene heterophasic copolymers are produced having increased impact strength through the use of controlled rheology techniques by the addition of a peroxide at conditions which increase the deactivation or half life of the peroxide. The increased half life slows down the vis-breaking process and allows better dispersion of rubber particles within the polymer. In this way, copolymers having a high melt flow can be prepared while obtaining high impact strength and lower stiffness values, without the need for additional elastomeric modifiers.
摘要翻译：通过在增加过氧化物的失活或半衰期的条件下通过加入过氧化物，通过使用受控的流变学技术制备具有增加的冲击强度的聚丙烯异相共聚物。增加的半衰期减慢了破坏过程，并允许橡胶颗粒在聚合物内更好的分散。以这种方式，可以制备具有高熔体流动性的共聚物，同时获得高冲击强度和较低的刚度值，而不需要额外的弹性体改性剂。

摘要： A fiber product drawn from an isotactic propylene copolymer of a C2, C4, C5, C6, C7 or C8 &agr;-olefin monomer produced in the presence of a metallocene catalyst characterized by a bridged chiral and stereorigid cyclopentadienyl or substituted cyclopentadienyl ligand structure of a transitional metal selected from group 4b, 5b, or 6b metals of the Periodic Table of Elements, the copolymer having a MFR less than 35, suitably about 30 or less. The copolymer is heated to a molten state and extruded to form a fiber preform. The preform is subjected to spinning at a spinning speed of at least 300 meters per minutes and subsequent drawing at a speed of up to about 1500 meters per minute to provide a draw ratio of at least 1.5 up to 5:1 to produce a continuous fiber having high tenacity of about 3.5 grams per denier and greater and good hand.

摘要： Process for the production of fibers formed from an ethylene-propylene copolymer characterized as a random copolymer of ethylene and isotactic polypropylene having a random ethylene content within the range of 2-12 mole %. The propylene content of the copolymer can have an isotacticity of at least 90% meso diads. The copolymer is heated to a molten state and then extruded to form a fiber preform. The fiber preform is subject to a spinning speed of at least 500 meters per minute. This is followed by drawing the spun fiber preform at a draw ratio within the range of 1:1-6:1 to produce a continuous fiber of the ethylene-propylene copolymer. A specific ethylene-propylene copolymer has an ethylene content within the range of 6-8%.
