Abstract
一种间同立构聚苯乙烯共混物，含有间同立构聚苯乙烯和聚亚芳基醚，其中聚亚芳基醚在25℃的氯仿中测量时，其特性粘度小于约0.25克/分升(g/dl)。
Description
背景技术
本发明涉及间同立构聚苯乙烯和聚亚芳基醚的共混物。
间同立构聚苯乙烯由于它的结晶形态而显然是具有优异的耐热和耐化学性。聚亚芳基醚与间同立构聚苯乙烯是高度互溶的，然而，聚亚芳基醚的存在可能损害间同立构聚苯乙烯结晶度的水平和比率。而结晶度的降低可能又使耐热和耐化学性都降低。
此外，基于其熔融温度和降解温度一般只有约30℃的差别这个事实，间同立构聚苯乙烯具有很小的加工温度范围。人们已经试图通过掺入添加剂，特别是流动促进剂，来改善这么窄的加工温度范围，以提高间同立构聚苯乙烯的可加工性。这些添加剂可能会削弱间同立构聚苯乙烯某些需要的物理性质，例如耐化学性、耐湿性和热变形温度。
发明概述
一种间同立构聚苯乙烯共混物，含有间同立构聚苯乙烯和聚亚芳基醚，其中聚亚芳基醚在25℃的氯仿中测量时，其特性粘度小于约0.25克/分升(g/dl)。

详细说明
一种间同立构聚苯乙烯共混物，含有间同立构聚苯乙烯和聚亚芳基醚，其中聚亚芳基醚在25℃的氯仿中测量时，其特性粘度小于约0.25克/分升(g/dl)。间同立构聚苯乙烯共混物具有比间同立构聚苯乙烯更低的熔融粘度，从而可以降低加工过程的降解量。间同立构聚苯乙烯共混物的熔融粘度优选小于或等于间同立构聚苯乙烯熔融粘度的约95％，更优选为小于或等于约90％，最优选为小于或等于约85％。熔融粘度越低，可能导致加工时间越短，同时还可以减少剪切生热。
采用低特性粘度聚亚芳基醚的间同立构聚苯乙烯共混物证明比对应的采用高特性粘度聚亚芳基醚的间同立构聚苯乙烯共混物具有更高水平的结晶度。这里所用的低特性粘度聚亚芳基醚定义为在25℃的氯仿中测量时，其特性粘度小于约0.25g/dl的聚亚芳基醚。高特性粘度聚亚芳基醚定义为在25℃的氯仿中测量时，其特性粘度大于约0.25g/dl的聚亚芳基醚。
含有低特性粘度聚亚芳基醚的间同立构聚苯乙烯共混物优选为具有大于或等于约30％的结晶度，更优选为大于或等于约40％的结晶度，最优选为大于或等于约50％的结晶度。与采用高特性粘度聚亚芳基醚的间同立构聚苯乙烯共混物不同，含有低特性粘度聚亚芳基醚的间同立构聚苯乙烯共混物即使快速冷却时也能具有高水平的结晶度。高水平的结晶度是需要的，因为结晶度水平一般与在高温下的耐化学性和尺寸稳定性直接相关。此外，当使低特性粘度聚亚芳基醚功能化后，间同立构聚苯乙烯共混物表现出与填充材料更好的黏结性，并且与其它热塑性材料(例如聚酰胺)的相容性和形态都得到了改善。
间同立构聚苯乙烯是一种具有高度规则立体化学结构的聚苯乙烯，也就是说，高度间同立构的构象。换句话说，侧基的苯基基团和取代的苯基基团是在相对于主聚合链的交替位置上。在立体化学结构中的立构规整度可以通过采用碳同位素(13C)的核磁共振(13C-NMR)来定量地确定。通过13C-NMR方法测得的立构规整度可以显示出序列的内容，其中在序列中特定数目的组成单元连在一起，例如，二单元组在序列中有两个组成单元连在一起，三单元组在序列中有三个组成单元连在一起，五单元组在序列中有五个组成单元连在一起。这里的间同立构聚苯乙烯定义为聚苯乙烯、聚烷基苯乙烯、聚卤代苯乙烯、聚卤代烷基苯乙烯、聚烷氧基苯乙烯、聚乙烯基苯甲酸酯、这些聚合物的氢化衍生物、含有上述聚合物之一的共混物、或者含有这些聚合物的组成单元作为主要组分的共聚物，它们一般具有的间同规整度根据外消旋二单元组的含量表示为75％或更大，优选为85％或更大，或者根据外消旋五单元组的含量表示为30％或更大，优选为50％或更大。
聚烷基苯乙烯的例子包括，但不限于，聚甲基苯乙烯、聚乙基苯乙烯、聚异丙基苯乙烯、聚叔丁基苯乙烯、聚苯基苯乙烯、聚乙烯基亚萘基、和聚乙烯基苯乙烯。聚卤代苯乙烯的例子包括聚氯代苯乙烯、聚溴代苯乙烯、和聚氟代苯乙烯。聚卤代烷基苯乙烯的例子包括聚氯代甲基苯乙烯。聚烷氧基苯乙烯的例子包括聚甲氧基苯乙烯和聚乙氧基苯乙烯。
间同立构聚苯乙烯的特别优选的例子包括聚苯乙烯、聚对甲基苯乙烯、聚间甲基苯乙烯、聚对叔丁基苯乙烯、聚对氯代苯乙烯、聚间氯代苯乙烯、聚对氟代苯乙烯、氢化苯乙烯，含有包括上述聚合物单元的共聚物和包括上述间同立构聚苯乙烯之一的组合物。
苯乙烯聚合物的分子量没有特别地限制。重均分子量优选为大于或等于约10,000，且优选为大于或等于约50,000。分子量分布没有特别地限制，可以采用具有各种各样的分子量分布的间同立构聚苯乙烯。
间同立构聚苯乙烯可以通过使苯乙烯基单体(与间同立构聚苯乙烯中重复单元相对的单体)在惰性烃溶剂中或者在不含溶剂条件下采用钛化合物和水与三烷基铝的缩聚产物作为催化剂进行聚合来制备。
间同立构聚苯乙烯一般用量为基于共混物总重量的大于或等于约40wt％，优选为大于或等于约50wt％，更优选为大于或等于约70wt％，以及用量小于或等于约99wt％，优选为小于或等于约98wt％，更优选为小于或等于约95wt％。
术语“聚亚芳基醚”包括聚苯醚(PPE)和聚亚芳基醚共聚物、接枝共聚物、聚亚芳基醚醚离子键共聚物；以及链烯基芳香族化合物、乙烯基芳香族化合物和聚亚芳基醚等的嵌段共聚物；以及含有前述化合物至少一种的组合。聚亚芳基醚本身是含有许多如式(I)结构单元的公知聚合物：
其中对于每一个结构单元，每一个Q1独立地为卤原子、伯或仲低级烷基(例如，含有直到7个碳原子的烷基)、苯基、卤代烷基、氨基烷基、烃氧基、卤原子和氧原子之间至少隔两个碳原子的卤代烃氧基等，以及每一个Q2独立地为氢、卤原子、伯或仲低级烷基、苯基、卤代烷基、烃氧基、卤原子和氧原子之间至少隔两个碳原子的卤代烃氧基等。优选地，每一个Q1为烷基或苯基，尤其是C1-4烷基，而每一个Q2为氢。
聚亚芳基醚既包括它的均聚物，也包括它的共聚物。优选的均聚物为那些含有2，6-二甲基聚亚芳基醚单元的化合物。适合的共聚物包括含有例如，与2，3，6-三甲基-1，4-苯基醚单元结合的这样的单元的无规共聚物，或者由2，6-二甲基苯酚与2，3，6-三甲基苯酚共聚合而衍生的共聚物。同样包括含有通过乙烯基单体或聚合物(例如苯乙烯)接枝而制备的基团的聚亚芳基醚，以及偶联的聚亚芳基醚，其中偶联剂(例如低分子量聚碳酸酯、苯醌、杂环化合物和甲醛)以公知的方式与两个聚亚芳基醚链的羟基基团反应生成更高分子量的聚合物。本发明的聚亚芳基醚还包括含有至少一种上述化合物的组合。
聚亚芳基醚一般具有数均分子量为约2,000-约12,000原子质量单位(amu)，重均分子量为约5,000-约25,000amu，通过凝胶渗透色谱测定。聚亚芳基醚的特性粘度在25℃氯仿中测量为小于约0.25分升/克(dl/g)，优选为小于约0.15dl/g，更优选为约0.12dl/g。
聚亚芳基醚一般通过至少一个单羟基芳香族化合物(例如2，6-二甲苯酚或2，3，6-三甲苯酚)的氧化偶联来制备。对于这样的偶联一般采用催化剂体系，它们一般含有至少一种重金属化合物，例如铜、锰或钴化合物，常常与其它各种各样的物质配合使用。
聚苯基醚共聚物也可以具有不同的端基，例如含有氨基烷基的端基和4-羟基联苯端基，一般通过在氧化偶联反应合成时插入。聚苯基醚树脂可以通过端基功能化或封端，这样可以使聚合物增加更多的反应活性并在某些情况下还可能提供额外的与添加剂和其它聚合物树脂(可以用来制备合金或共混物)的相容性。例如，聚苯基醚可以通过将聚苯基醚共聚物与本领域公知的功能化试剂，用环氧端基、磷酸盐端基、丙烯酸酯或甲基丙烯酸酯端基或者原酸酯端基来功能化。
很显然对于本领域的熟练技术人员来说，通过上述说明，预想的聚亚芳基醚包括所有那些已经公知的化合物，而不考虑其结构单元或附属化学特征的变化。

所有专利在这里作为参考文献引用。本发明还通过下面的具体实施例进一步说明，但这些实施例并不是要限制本发明。
实施例1
将重均分子量(Mw)为250,000原子质量单位的间同立构聚苯乙烯与30重量百分数(wt％)的特性粘度为0.12dl/g或0.40dl/g的聚亚芳基醚结合。随后采用平行板动态粘度计在280℃下测量熔融粘度。从图1可以看出，含有特性粘度为0.40dl/g的聚亚芳基醚的共混物比未共混的间同立构聚苯乙烯具有更高的熔融粘度，而含有特性粘度为0.12dl/g的聚亚芳基醚的共混物比未共混的间同立构聚苯乙烯的熔融粘度低。
实施例2
将间同立构聚苯乙烯、含有30wt％玻璃纤维的间同立构聚苯乙烯、和含有抗冲击改良剂的间同立构聚苯乙烯与不同含量的特性粘度为0.12dl/g或0.40dl/g的聚亚芳基醚结合。在290℃下测量毛细管粘度。从图2可以看出，含有特性粘度为0.12dl/g的聚亚芳基醚的共混物比间同立构聚苯乙烯或者间同立构聚苯乙烯与特性粘度为0.40dl/g的聚亚芳基醚的共混物明显具有更低的粘度。
实施例3
将间同立构聚苯乙烯、含有30wt％玻璃纤维的间同立构聚苯乙烯、和含有抗冲击改良剂的间同立构聚苯乙烯与不同含量的特性粘度为0.12dl/g或0.40dl/g的聚亚芳基醚结合。共混物和间同立构聚苯乙烯从熔融态以受控的冷却速率(20℃/分钟)重结晶。通过差示扫描量热法(DSC)测定结晶度。如图3所示的结果表明在给定水平的聚亚芳基醚的情况下，含有特性粘度为0.12dl/g的聚亚芳基醚的共混物比含有特性粘度为0.40dl/g的聚亚芳基醚的共混物具有更高水平的结晶度。这种差别在含有填料的共混物和含有大于30wt％聚亚芳基醚的共混物中特别明显。
实施例4
共混物含有间同立构聚苯乙烯和20wt％的具有特性粘度为0.12dl/g的聚亚芳基醚或者20wt％的具有特性粘度为0.40dl/g的聚亚芳基醚。随后将这些共混物从熔融态以不同的(冷却)速率重结晶，通过DSC测定最终的结晶度。从图4可以看出，在高冷却速率的条件下，含有特性粘度为0.12dl/g的聚亚芳基醚的共混物比含有特性粘度为0.40dl/g的聚亚芳基醚的共混物具有更高水平的结晶度。
通过上述实施例可以看出，含有低粘度聚亚芳基醚的间同立构聚苯乙烯共混物比间同立构聚苯乙烯或间同立构聚苯乙烯与高粘度聚亚芳基醚的共混物具有更低的粘度。此外，含有低粘度聚亚芳基醚的共混物比含有高粘度聚亚芳基醚的共混物具有更高水平的结晶度。
在已经显示和说明了本发明优选的一些实施方案的同时，还可以对其作出不偏离本发明构思和范围的各种各样修改和替换。因此，本发明应当被理解为已经是通过举例性而不是限制性的方式作了说明。
