Abstract

Description
本发明涉及乙烯共聚物,该共聚物由乙烯单元和至少一种C3-C12α-烯烃组成,其具有超过3的分子量分布Mw/Mn,及由均重(average-weighted)洗脱温度Ta的标准偏差σ表征的共聚单体分布,其由温度提升洗脱分数(TREF)确定,其遵守下面公式GI:
σ<k4-k1(Tako)-k2k3(Ta-ko)/(1+k3(Ta-ko)) [℃]
GI
其中,ko为338.5℃,k1为0.053,k2为1.1318℃,k3为0.00483℃-1,k4为0.55℃,Ta<98℃。
本发明还涉及一种制备如此乙烯共聚物的方法,涉及乙烯共聚物在制备薄膜,中空体和纤维上的应用,同时也涉及由使用这些乙烯共聚物而制备的薄膜,中空体和纤维。
当乙烯与其它α-烯烃进行共聚时,期望在获得的乙烯共聚物中,这些共聚单体具有高包合度。当使用金属茂催化剂时,且当使用如此催化剂,通过调节这些金属配合物的配位体结构能控制该催化剂时,共聚单体的包合效率非常高。
通常认为,金属茂中环戊二烯基环之间的孔径角度对包合性质具有明显的影响。大孔径角度可通过如SiMe2或C2H4桥桥连这些环获得。如此金属茂催化剂描述在如EP336,128中。
对于如此共聚,工业上最有效的聚合方法为气相聚合方法和悬浮聚合方法。为进行如此聚合方法,需要将该催化剂置于如硅胶的颗粒状载体上。
加载金属茂催化剂的方法描述在如WO95/07939,WO87/03889,WO94/28034,EP206,794和EP250,600中。在这些情况下,MAO(甲基铝氧烷(aluminoxane))或其它铝氧烷用作共催化剂。此外,其中硼化合物用作活化剂的金属茂的加载方法已有描述(如WO91/09882 WO94/03506 WO95/14044EP628,574 WO95/15815)。
使用这些载体催化剂制备的聚合物基本上具有非常窄的分子量分布及非常均匀的共聚单体包合,其导致某些期望的性质,如由这些材料制备的薄膜具有良好的强度和亮度。然而,由于窄分子量分布,在聚合物工业中,其在很大程度上妨碍了在常规使用的机器上的加工。如当使用铬或钛催化剂时可获得的具有宽分子量分布的聚合物能够非常容易地进行加工,但其面临的缺陷是,共聚单体(丁烯,己烯,辛烯)不均等地分布在聚合物分子上。这样,低分子量部分的共聚单体的浓度明显地高于高分子量部分的浓度。其结果是,这些易于加工的聚合物具有不能令人满意的机械性能。
使用金属茂催化剂,制备具有宽分子量分布共聚物的所有公知尝试已导致不能令人满意的产物。如EP-A613,908描述了具有分子量分布Mw/Mn高至32的共聚物的制备,但这些共聚物同时也具有宽共聚单体分布。
WO93/09148也描述了具有宽分子量分布的共聚物,但该分子量分布的加宽是以宽共聚单体的分布和高含量的低分子为代价的,其导致己烷可萃取的高含量为4.1-13.3%。
DE19,606,167描述载体催化剂体系,籍助于该催化剂体系,可制备具有窄共聚单体分布和窄分子量分布的聚合物。这些催化剂体系含有具有桥连或非桥连金属茂配位体的金属茂配合物。此文献没有提及共聚合或其产物。
由此,本发明的一个目的是提供一种乙烯共聚物,该共聚物包括乙烯单元和至少一种C3-C12α-烯烃,其在仍旧展示窄共聚单体分布的同时,具有大于3的分子量分布。
因此,我们发现了上述定义的乙烯共聚物。我们也发现了制备如此共聚物的方法,这些共聚物在制备薄膜,中空体和纤维上的应用,以及由这些共聚物生产的薄膜,中空体和纤维。
在本发明共聚物中的窄共聚单体分布可基于均重洗脱温度Ta的标准偏差而进行有益的描述,如可由TREF方法确定。TREF方法描述在如Wild,Advancesin Polymer Science,98,页1-47,1990,Springer-Verlag和Wild,Blatz,Polymer Mater.Sci.Eng.67,153页,1992中。均重洗脱温度(Ta)和标准偏差(σ)以下面方式使用(如Bevington,McGraw-Hill,Data Reductin and Error Analysis for the Physical Sciences,1969):
Ta=∑(c(Ti)*Ti)/∑c(Ti) [℃]
σ=([∑(Tita)2*c(Ti)]/∑c(Ti))1/2 [℃]
在此,Ti为点i的温度,c(Ti)为在温度Ti时的聚合物浓度。
现在,本发明的共聚物具有非常小的标准偏差σ,其可通过使用上述ko,k1,k3和k4值,由公式GI确定。
其中标准偏差σ足够小以符合公式I的共聚物为特别优选,其中ko为496.6℃,k1为0.0467,k2为1.1318℃,k3为0.00483℃-1,k4为0.55℃,Ta<98℃。
本发明共聚物的有益性质基本上由窄共聚单体分布与相对宽分子量分布的相结合获得。该分子量分布Mw/Mn值必须大于3,优选大于3且小于8,更优选的值为3.5-7.0。
本发明的共聚物不仅含有乙烯单元,而且含有至少一种C3-C12α-烯烃单元。适合的α-烯烃为丙烯,丁烯,戊烯,己烯,庚烯,辛烯,壬烯,癸烯,十一碳烯和十二碳烯。衍生于丁烯和己烯的共聚单体为优选。
共聚物中共聚单体的量由该共聚物所需要的质量密度进行控制。本发明的共聚物通常具有这样的共聚单体含量:其使共聚物的质量密度为0.87-0.96g/cm3,优选0.90-0.94g/cm3,更优选0.910-0.935g/cm3。
本发明的共聚物可展示出宽范围的分子量,其中将分子量调节到期望的值可通过本领域技术人员熟悉的方法进行,也就是说,如通过改变聚合温度或使用如氢气的试剂而进行。该聚合物通常具有的分子量Mw超过100,000,优选超过150,000。
而且,优选具有少含量低分子聚合物链的共聚物。例如,可由庚烷可萃取的含量表征的这部分对共聚物的感觉检测(sensory examination)具有负面影响。本发明共聚物中庚烷可萃取的含量,基于全部共聚物的重量,优选小于4wt%,更优选小于1wt%,特别优选小于0.1wt%。
展示出由本发明提供的一组性质的共聚物可以各种方式进行制备。如此制备方法中的一个有益实例为这样一种方法,其特征在于,共聚合是通过使用一种载体催化剂体系进行,该载体催化剂体系可通过以下反应而获得:
