Abstract
本发明公开了用于烯烃单体的聚合和共聚以及烯烃单体与选自例如降冰片烯类和苯乙烯类中的其它单体的共聚的聚合催化剂。所公开的聚合催化剂含有选自选自Ti,Zr,Hf,Ni和Pd中的金属中心与至少一个螯合配体。
Description
本发明涉及可用于烯烃的聚合和共聚的聚合催化剂。本发明还涉及使用此类聚合催化剂的烯烃聚合和共聚方法。
烯烃的聚合物和共聚物一般显示了适合用于许多应用领域的优异机械性能。这些材料被广泛使用,所以很难想象没有它们的生活会是什么样。质轻、防水和耐腐蚀,它们常常是这些根本不同的制品比如水管、垃圾袋、发梳、衣服和道路构筑用纤维、汽车车身部件、以及食品和药物用包装的设计者的第一选择。
用于烯烃的聚合和共聚的一类催化剂由Matsui等人公开在US专利No.6,593,266中。Matsui等人公开了含有(A)用通式(i)表示的过渡金属化合物,任选的(B)选自有机金属化合物,有机铝氧基化合物和与过渡金属化合物(A)反应形成离子对的化合物中的至少一种化合物的催化剂。如下所示,通式(i)被Matsui等人所公开:
其中M是选自周期表的3-11族中的过渡金属原子;m是1-6的整数;A是-O-,-S-,-Se-,或-N(R5)-;D是-C(R7)(R8)-,-Si(R9)(R10)-等;Z是-R13和-R14,=C(R15)R16,=NR17等,R1-R17各自选自H,烃基等;n是满足M的化合价的数值;和X是卤素,烃基等。
虽然如此,对于表现高聚合活性的新型烯烃聚合催化剂仍然存在着需求。还有,对于提供基本上线性的产物(即具有较低支化度的聚乙烯)的乙烯聚合用催化剂存在着需求。另外对于能够制备基本线性的聚合物,同时表现了对极性杂质的耐受性,使得它们能够使携带极性取代基的单体共聚的催化剂存在着需求。本发明的聚合催化剂可以满足这些需求的一个或多个。
在本发明的一个方面,提供了聚合催化剂,包括:选自钛(Ti),锆(Zr),铪(Hf),镍(Ni)和钯(Pd)中的金属中心和至少一个螯合配体,后者包含碳烯与至少一阴离子结构部分,其中该至少一个螯合配体具有选自通式I-IV中的结构:
其中R是任何烃基;各R1独立是任何烃基;R2是任何烃基;和X选自氧,氮和硫;其中碳烯和阴离子结构部分配位于该金属中心。
在本发明的另一个方面,提供了制备均聚物的方法,包括让至少一种α-烯烃单体与聚合催化剂在铝活化剂的存在下接触,其中该聚合催化剂包括:选自钛(Ti),锆(Zr)和铪(Hf)中的金属中心和两个包含碳烯与至少一阴离子结构部分的螯合配体,其中各螯合配体具有独立选自通式I-IV中的结构;其中R是任何烃基;各R1独立是任何烃基;R2是任何烃基;和X选自氧、氮和硫;其中碳烯和阴离子结构部分均配位于该金属中心。
在本发明的另一个方面,提供了制备共聚物的方法,包括让选自α-烯烃,降冰片烯类和苯乙烯类中的至少两种不同单体与聚合催化剂在铝活化剂的存在下接触,其中该聚合催化剂包括:选自钛(Ti),锆(Zr)和铪(Hf)中的金属中心和两个包含碳烯与至少一阴离子结构部分的螯合配体,其中各螯合配体具有独立选自通式I-IV中的结构;其中R是任何烃基;各R1独立是任何烃基;R2是任何烃基;和X选自氧、氮和硫;其中碳烯和阴离子结构部分均配位于该金属中心。
在本发明的另一个方面,提供了制备均聚物的方法,包括任选在铝活化剂的存在下,让乙烯与聚合催化剂接触,其中该聚合催化剂包括选自镍(Ni)和钯(Pd)中的金属中心和包含碳烯与至少一阴离子结构部分的螯合配体,其中该螯合配体具有选自通式I-IV中的结构;其中R是任何烃基;各R1独立是任何烃基;R2是任何烃基;和X选自氧、氮和硫;其中碳烯和阴离子结构部分均配位于该金属中心。
在本发明的另一个方面,提供了制备共聚物的方法,包括任选在铝活化剂的存在下,让乙烯、丙烯酸类单体和聚合催化剂接触,其中该聚合催化剂包括选自镍(Ni)和钯(Pd)中的金属中心和包含碳烯与至少一阴离子结构部分的螯合配体,其中该螯合配体具有选自通式I-IV中的结构;其中R是任何烃基;各R1独立是任何烃基;R2是任何烃基;和X选自氧、氮和硫;其中碳烯和阴离子结构部分均配位于该金属中心。
在本发明的另一个方面,提供了制备共聚物的方法,包括在铝活化剂的存在下,让聚合催化剂与选自α-烯烃,降冰片烯类和苯乙烯类中的至少两种不同单体接触,其中该聚合催化剂包括:选自钛(Ti),锆(Zr)和铪(Hf)中的金属中心和两个包含碳烯与至少一阴离子结构部分的螯合配体,其中各螯合配体具有独立选自通式I-IV中的结构;其中R是任何烃基;各R1独立是任何烃基;R2是任何烃基;和X选自氧、氮和硫;其中碳烯和阴离子结构部分均配位于该金属中心。
