  摘要：

  本发明涉及将低乙烯插入到α-烯烃聚合物中，以及使用非桥联流动金属芳基茚基金属卡宾化物，主要是取代芳基茚基金属卡宾化物的生产这种聚合物的工艺。更具体地说，本发明涉及使用非桥联流动环戊二烯基或茚基金属卡宾化物催化剂体系的方法生产高熔点α-烯烃同聚物和共聚物，特别是α-烯烃的弹性结晶和非晶块同聚物和共聚物。含有至少一个2-芳基茚烯配体的流动非桥联金属卡宾化物聚合催化剂的活性通过向聚合体系中添加少量（通常为0.1-10重量％）乙烯而增加10倍或更多，这种增加被称为聚合速率增强效应（PRE），其以无量纲比例的乙烯增强因子（EEF）的形式进行测量，范围为约1.1到约10或以上。本发明的第二个重要方面是在α-烯烃聚合物中使用PRE活性增强量的乙烯，而不会对弹性体的物理性质产生实质影响。在本发明的第三个重要方面中，使用非桥联流动催化剂体系通过乙烯的引入生产α-烯烃弹性体，这种催化剂体系可能不会产生可接受的弹性同聚物。本发明的优选聚合物保持足够的结晶度，以提供约80℃，优选高于100℃，包括从约120℃到约140℃及以上的高熔点（通过DSC）。还揭示了具有超过600％的延展度和基本无保留力的新型柔性α-烯烃同聚物和共聚物。

  This invention relates generally to low ethylene insertions into &agr;-olefin polymers and processes for production of such polymers using unbridged fluxional metallocenes, primarily substituted aryl indenyl metallocenes, and more particularly to use of unbridged, fluxional, cyclopentadienyl or indenyl metallocene catalyst systems in methods of production of high melting point &agr;-olefin homo- and co-polymers, particularly elastomeric crystalline and amorphous block homo- and co-polymers of &agr;-olefins. The activity of fluxional unbridged metallocene polymerization catalysts containing at least one 2-arylindene ligand is increased 10× or more by the addition of small (typically 0.1-10 wt. %) amounts of ethylene to the polymerization system, which increase is termed the Polymerization Rate-Enhancement effect (PRE), which is measured in terms of an Ethylene Enhancement Factor (EEF) as a dimensionless ratio in the range of from about 1.1 to about 10 or above. The amount of ethylene included in the reaction system can be selected and controlled to be so small as to result in essentially minimal (<2 mole %) incorporation of ethylene units into the resulting elastomeric polymer and the molecular weight may be increased. Amounts of ethylene to generate the PRE effect may be greater than 0.1 wt. % and preferably range up to about 2 wt. %. However, if a polymer with more ethylene is desired, additional ethylene may be incorporated into the polymerization feed, including up to 10 to about 50 mole % based on olefin units. A second important aspect of this invention is the ability to use a PRE activity-enhancing amount of ethylene in an olefin polymerization without substantially affecting the physical properties of the elastomer. In a third important aspect of this invention, &agr;-olefin elastomers are produced through incorporation of ethylene using unbridged fluxional catalyst systems which may not otherwise produce acceptable elastomeric homopolymers. This effect is termed the EPE effect, for Elastomeric Property-Enhancing effect. The EPE amount of ethylene required to produce such elastomers typically overlaps the PRE activity-enhancing amount. Incorporation of up to about 5 mole % or more of ethylene typically will produce an elastomeric polymer using such catalyst systems. Typical useful amounts of incorporated ethylene include about 1 to 3 mole %. Preferred polymers of this invention retain sufficient crystallinity to provide a high melting point (by DSC) of about 80° C., preferably above 100° C., including in the range of from about 120° C. to about 140° C. and above. Novel flexible &agr;-olefin homo and copolymers having elongation in excess of 600% and substantially no retained force are disclosed.
