Description
发明背景
高性能聚合物诸如热致液晶聚合物(“LCP”)通常用于形成模制部件(例如电连接器)。这类聚合物的一个好处在于其可展示相对高的“流动”,这是指当在剪切下加热时,聚合物以快速率均一地填充复杂部件而无过量溢出或其他有害处理问题的能力。除了能够适应复杂部件几何形状,高聚合物流量还可提高模制部件的最终性能。最明显地,由良好流动性聚合物制造的部件一般展示因更低的模制内应力带来的改进的尺寸稳定性,这使得该组件对下游热处理来说更可修改,所述下游热处理可受到来自较差模制材料中发生的翘曲及其他聚合物应力松弛不利地影响。尽管其相对高的流量能力,许多高性能聚合物仍缺乏满足复杂部件设计的提高的模制要求而不显著损失其最终产品性能所需要的。就此而言,持续需要一种除其他可能的用途之外,还可与高性能聚合物组合使用的新型化合物。

详细描述
本领域普通技术人员应理解,本发明的论述仅为示例性实施方式的描述,并不意图限制本发明的更广范围的方面。
本发明一般关于一种具有如下通式(I)的芳族酰胺化合物:
其中,
X1及X2独立地为C(O)HN或NHC(O);
G1、G2及G3、独立地为氢、C(O)HN-苯基或NHC(O)-苯基,其中G1、G2及G3中的至少一个为C(O)HN-苯基或NHC(O)-苯基;
Q1、Q2及Q3独立地为氢、C(O)HN-苯基或NHC(O)-苯基,其中Q1、Q2及Q3中至少一个为C(O)HN-苯基或NHC(O)-苯基;
R5为卤素、卤代烷基、烷基、烯基、芳基、杂芳基、环烷基或杂环基;及
m为0-4。
在某些实施方式中,该化合物为二官能化合物,其中核心苯环直接键连至仅两个酰胺基团(例如C(O)HN或NHC(O))。在这样的实施方式中,式(I)中的m可为0。这样的化合物的一个特定实施方式具有如下通式(II):
其中,G1、G2、Q1及Q2是如上所定义的。例如,G3及Q3一般为氢。而且,在一些实施方式中,G1及Q1可为氢且G2及Q2可为C(O)NH-苯基或NHC(O)-苯基。替代地,G2及Q2可为氢且G1及Q1可为C(O)NH-苯基或NHC(O)-苯基。
当然,该核心苯环也可直接键连至三个或更多个酰胺基团。例如,通过通式(III)提供该化合物的一个特定实施方式:
其中,
G1、G2、G3、Q1、Q2、及Q3是如上所定义的;及
Y1、Y2及Y3独立地为氢、C(O)HN-苯基或NHC(O)-苯基,其中Y1、Y2及Y3中的至少一个为C(O)HN-苯基或NHC(O)-苯基。例如,Y3、G3及Q3一般为氢。而且,在一些实施方式中,Y1、G1及Q1可为氢及Y2、G2及Q2可为C(O)NH-苯基或NHC(O)-苯基。替代地,Y2、G2及Q2可为氢且Y1、G1及Q1可为C(O)NH-苯基或NHC(O)-苯基。
也在下表中阐明本发明的芳族酰胺化合物的具体实施方式:
可利用多种不同的技术制备文中公开的化合物。例如,可初始通过芳族酰氯(例如苯甲酰氯)与使用一种或多种胺类(例如胺、二胺、三胺等)取代的苯基之间的亲核加成/消除反应,形成前体氨基苯基酰胺。这类经胺取代的苯基的特定实例包括1,3-苯二胺及1,4-苯二胺。在苯环上胺取代的位置可影响所得酰胺前体的立体化学。例如,苯甲酰氯与1,3-苯二胺的反应可产生具有如下结构的经3-氨基苯基取代的苯甲酰胺前体:
同样地,与1,4-苯二胺的反应可产生具有如下结构的经4-氨基苯基取代的苯甲酰胺前体:
无论如何,所得酰胺前体可进一步与二酰氯/或三酰氯反应以产生所需化合物。例如,二酰氯(例如间苯二甲酰氯)一般产生“双主题”化合物,其中核心苯环键连至仅两个酰胺基团,而三酰氯(例如均苯三甲酰氯)一般产生“三主题”化合物,其中核心苯环键连至三个酰胺基团。在以下实施例中将更详细地描述用于形成本发明的化物合的这类技术。应理解,在给定处理条件(即反应温度、时间、反应物的摩尔比、溶剂、压力等)时,除非另有说明,否则也可使用其他处理条件。最佳反应条件可随所使用的特定反应物或溶剂而变化。但本领域技术人员可以通过常规优化过程确定这样的条件。此外,如本领域技术人员将要明白的,可将包含一个或多个手性中心的化合物作为纯立体异构体(即个别对映异构体或非对映异构体)或作为富集立体异构体的混合物制备或分离。本发明的范围内包括所有这类立体异构体(或富集的混合物)。可利用例如本领域中已熟知的光学活性起始材料或立体选择性试剂制备纯立体异构体(或富集的混合物)。替代地,可利用例如手性柱状色谱法、手性拆分剂等分离这类化合物的消旋混合物。
本发明的化合物可具有多种不同的用途。例如,本发明人发现:通过改变分子间聚合物链的相互作用,因而降低在剪切下的该聚合物基质的总粘度,其可充当用于热致液晶聚合物的流动助剂。除简单地减小粘度外,该芳族酰胺化合物在配料、模制和/或使用期间不可轻易挥发或分解。这使否则会影响由该聚合物组合物制造的部件的最终机械性质的气体逸出及气泡的形成降到最低。未意图受限于理论,相信该酰胺官能基的活性氢原子能够与液晶聚酯或聚酯酰胺的主链形成氢键。此氢键合强化该化合物与该液晶聚合物基质的连接,并因此将在形成期间其变得挥发的可能性降至最低。在提供所表明的好处的同时,该芳族酰胺化合物一般不与该液晶聚合物的聚合物主链反应至任何可观的程度,以致不会不利地影响该聚合物的机械性质。
当用作流动助剂时,本发明的芳族酰胺化合物一般具有相对低的分子量。例如,该化合物可具有约2,500克/摩尔或更小,在一些实施方式中约200-约1,500克/摩尔,在一些实施方式中约300-约1,200克/摩尔及一些实施方式中约400-约1,000克/摩尔的分子量。该化合物一般也可具有高酰胺官能度,因此其能够与该液晶聚合物进行足够程度的氢键合。针对给定分子的酰胺官能的程度可由其“酰胺当量”来表征,它反映包含一分子酰胺官能团的化合物的量及可由将该化合物的分子量除以该分子中的酰胺基团的数目来计算。例如,该芳族酰胺化合物每分子可包含4-8,在一些实施方式中4-6个酰胺官能团。该酰胺当量可同样地为约10-约1,000克/摩尔或更小,在一些实施方式中约50-约500克/摩尔,及在一些实施方式中约100-约300克/摩尔。
如本领域中已知的,可改变可与本发明的化合物组合使用的热致液晶聚合物的类型。适合的液晶聚合物一般为具有相对刚性及直链的聚合物链,以使其熔化以形成液晶相的缩合聚合物。这类聚合物的实例可包括例如芳族或脂族聚酯类、芳族或脂族聚(酯酰胺类)、芳族或脂族聚(酯碳酸酯类)、芳族或脂族聚酰胺类等。这类聚合物可例如包含由一种或多种芳族或脂族羟基羧酸类、芳族或脂族二羧酸类、芳族或脂族二醇类、芳族或脂族氨基羧酸类、芳族或脂族胺类、芳族或脂族二胺类等以及其组合形成的重复单元。

该液晶聚合物一般具有约2,000克/摩尔或更大,在一些实施方式中约4,000克/摩尔或更大,及在一些实施方式中约5,000-约30,000克/摩尔的数平均分子量(Mn)。当然,还可以形成具有更低分子量的聚合物,诸如小于约2,000克/摩尔。一般与分子量成正比例的聚合物组合物的特性粘度可同样地为约2公升/克(“dL/g”)或更大,在一些实施方式中约3dL/g或更大,在一些实施方式中,约4-20dL/g,及在一些实施方式中约5-约15dL/g。如下面将更详细地描述的,可根据ISO-1628-5,利用五氟苯酚及六氟异丙醇的50/50(v/v)混合物测定特性粘度。
任选该液晶聚合物与该芳族酰胺化合物的相对比例以有助于达到粘度与机械性质之间的平衡。更具体地说,高芳族酰胺化合物含量可导致低粘度,但含量过高可将粘度减小至该化合物不利地影响该聚合物共混物的熔体强度的程度。在大多数实施方式中,例如,该芳族酰胺化合物或其混合物可以相对于100重量份的该液晶聚合物约0.1-约5重量份,在一些实施方式中约0.2-约4重量份及在一些实施方式中约0.3-约1.5重量份的含量使用。芳族酰胺化合物可例如构成约0.1重量%-5重量%,在一些实施方式中约0.2重量%-约4重量%及在一些实施方式中约0.3重量%-约1.5重量%的该聚合物组合物。液晶聚合物可同样地构成约95重量%-约99.9重量%,在一些实施方式中约96重量%-98.8重量%及在一些实施方式中约98.5重量%-约99.7重量%的该聚合物组合物。
如本领域已知,可改变该化合物与该液晶聚合物组合的方式。例如,可将原材料同时或按序供应至分散地共混材料的熔融处理装置中,可使用分批和/或连续熔融处理技术。例如,可利用混合机/捏合机、Banbury混合机、法雷尔式连续混合机(Farrel continuous mixer)、单螺杆挤出机、双螺杆挤出机、滚轧机等,以共混及熔融处理材料。一种特别适合的熔融处理装置为同向双螺杆挤出机(例如,Leistritz同向全啮合双螺杆挤出机)。这类挤出机可包括进料口及排出口及提供高强度的分配及分散混合。例如,可将液晶聚合物及化合物进料至双螺杆挤出机的相同或不同进料口及熔融共混以形成实质上均质的熔融混合物。可在高剪切/压力及加热下发生熔融共混以确保足够的分散。例如,可在约50℃-约500℃及在一些实施方式中约100℃-250℃的温度下发生熔融处理。同样地,在熔融处理期间的装置剪切速率可在约100秒-1-约10,000秒-1及在一些实施方式中约500秒-1-约1,500秒-1。当然,也可控制其他变量,诸如与吞吐率成反比的在熔融处理期间的停留时间,以达到所需均质化程度。
除了熔融共混,也可采用其他技术以组合化合物及液晶聚合物。例如,可在该液晶聚合物的聚合的一个或多个阶段期间供应该化合物。在这类实施方式中,一般要求在已经引发熔融聚合之前施用该化合物,及一般与液晶聚合物的前体单体结合。无论将其引入的方式,该芳族酰胺化合物可降低所得聚合物组合物的熔体粘度。例如可降低该熔体粘度,以使起始液晶聚合物粘度与经共混的组合物粘度之比至少为约1.1,在一些实施方式中至少约1.2,在一些实施方式中约1.5-约50,在一些实施方式中约2-约40及在一些实施方式中约4-约30。在一个特定实施方式中,该聚合物组合物可具有在1000秒-1剪切速率下测定的约0.5-约100Pa-s,在一些实施方式中约1-约80Pa-s及在一些实施方式中约2-约50Pa-s的熔体粘度。可根据ISO测试号11443(相当于ASTM测试号1238-70),在350℃的温度下测定熔体粘度。该聚合物组合物的熔点也可为约250℃-约400℃,在一些实施方式中约270℃-约380℃及在一些实施方式中约300℃-约360℃。同样地,结晶温度可为约200℃-约400℃,在一些实施方式中约250℃-约350℃及在一些实施方式中约280℃-约320℃。如相关技术中已知,可利用差示扫描量热法(“DSC”)测定熔融及结晶温度,诸如通过ISO测试号11357测定。
如果需要,所得聚合物组合物也可与多种其他类型的组分组合以形成经填充的组合物。例如,可将填料物质并入该聚合物组合物以提高强度。经填充的组合物可包括填料材料诸如纤维填料和/或矿物填料,及可选的一种或多种如本领域一般已知的其他添加剂。
例如,可将矿物质填料用于聚合物组合物中以有助于达成要求的机械性质和/或外观。当使用时,矿物质填料一般占该聚合物组合物的约5重量%-约60重量%,在一些实施方式中约10重量%-约55重量%,及在一些实施方式中约20重量%-约50重量%。粘土矿物质可尤其适合用于本发明中。这类粘土矿物质的实例包括,例如,滑石(Mg3Si4O10(OH)2)、埃洛石(Al2Si2O5(OH)4)、高岭石(Al2Si2O5(OH)4)、伊利土((K,H3O)(Al,Mg,Fe)2(Si,Al)4O10[(OH)2,(H2O)]、蒙脱石(Na,Ca)0.33(Al,Mg)2Si4O10(OH)2·nH2O)、蛭石((MgFe,Al)3(Al,Si)4O10(OH)2·4H2O)、坡缕石((Mg,Al)2Si4O10(OH)·4(H2O))、叶蜡石(Al2Si4O10(OH)2)等,以及它们的组合。代替粘土矿物质或除其以外,也可使用其他矿物质填料。例如,也可使用其他适宜的硅酸盐填料,诸如硅酸钙、硅酸铝、云母、硅藻土、硅灰石等。例如,云母尤其适合。存在在地质产状中具有极大差异的若干化学上不同的云母物质,但均具有实质上相同的晶体结构。文中所用的术语“云母”意指一般包括这些物质的任何一种,诸如白云母(KAl2(AlSi3)O10(OH)2)、黑云母(K(Mg,Fe)3(AlSi3)O10(OH)2)、金云母(KMg3(AlSi3)O10(OH)2)、锂云母(K(Li,Al)2-3(AlSi3)O10(OH)2)、海绿石(K,Na)(Al,Mg,Fe)2(Si,Al)4O10(OH)2)等,以及它们的组合。
也可使用纤维作为填料材料以进一步改善机械性质。这类纤维相对其质量一般具有高度的拉伸强度。例如,该纤维的最终拉伸强度(根据ASTM D2101测定)一般为约1,000-约15,000兆帕(“MPa”),在一些实施方式中约2,000-约10,000MPa,及在一些实施方式中约3,000-约6,000MPa。为有助于保持通常在电子组件应用中所需的绝缘性,高强度纤维可由在性质上亦一般为绝缘的材料形成,诸如玻璃、陶瓷(例如氧化铝或硅石)、芳族聚酰胺类(例如,由E.I.duPont deNemours,Wilmington,Del.出售的Kevlar)、聚烯烃、聚酯类等,以及它们的混合物。玻璃纤维尤其适宜,诸如E-玻璃、A-玻璃、C-玻璃、D-玻璃、AR-玻璃、R-玻璃、S1-玻璃、S2-玻璃等及其混合物。
纤维的体积平均长度可为约50-约400微米,在一些实施方式中约80-约250微米,在一些实施方式中约100-约200微米,及在一些实施方式中约110-约180微米。该纤维也可具有窄的长度分布。意即,至少约70体积%的纤维,在一些实施方式中至少约80体积%的纤维,及在一些实施方式中,至少约90体积%的纤维具有位于约50-约400微米,在一些实施方式中约80-约250微米,在一些实施方式中约100-约200微米,及在一些实施方式中约110-约180微米的范围内的长度。该纤维也可具有相对高的长径比(平均长度标称直径除以)以有助于改善所得聚合物组合物的机械性质。例如,该纤维可具有约2-约50,在一些实施方式中约4-约40的长径比,及在一些实施方式中约5-约20尤其有利。纤维可例如具有约10-约35微米,及在一些实施方式中约15-约30微米的标称直径。
也任选性地控制经填充的聚合物组合物的纤维的相对含量,以有助于达成所需机械性质而不有害地影响该组合物的其他性质,诸如它的可流动性。例如,该纤维可占该聚合物组合物的约2重量%-约40重量%,在一些实施方式中约5重量%-约35重量%,及在一些实施方式中约6重量%-约30重量%。虽然可在以上表明的范围内使用该纤维,但是仍可在达成所需机械性质的同时使用小纤维含量。例如,可以使用少量该纤维,诸如约2重量%-约20重量%,在一些实施方式中约5重量%-约16重量%,及在一些实施方式中约6重量%-约12重量%。
可并入该组合物中的其他添加剂可包括,例如抗菌剂、颜料(例如,碳黑)、抗氧化剂、稳定剂、表面活性剂、蜡、固体溶剂,及添加以提高性质及可处理性的其他材料。例如,在聚合物组合物中可使用润滑剂。这类润滑剂的实例包括脂肪酸酯、其盐类、酯类、脂肪酸酰胺、有机磷酸酯、及在工程塑料材料的处理中通常用作润滑剂的烃蜡类型,包括其混合物。适宜的脂肪酸一般具有约12-约60个碳原子的主链碳链,诸如肉豆蔻酸、棕榈酸、硬脂酸、花生酸、褐煤酸、十八烯酸(octadecinic acid)、帕里拉油酸(parinric acid)等。适宜的酯类包括脂肪酸酯、脂肪醇酯、蜡酯、甘油酯、乙二醇酯及复酯。脂肪酸酰胺包括脂肪一级酰胺、脂肪二级酰胺、亚甲基及亚乙基双酰胺,及烷醇酰胺诸如棕榈酸酰胺、硬脂酸酰胺、油酸酰胺、N,N′-亚乙基双硬脂酰胺等。也适宜的为脂肪酸的金属盐类,诸如硬脂酸钙、硬脂酸锌、硬脂酸镁等;烃蜡,包括石蜡、聚烯烃及氧化聚烯烃蜡及微晶蜡。尤其适宜的润滑剂为硬脂酸的酸类、盐类或酰胺类,诸如四硬脂酸季戊四醇酯、硬脂酸钙或N,N′-亚乙基双硬脂酰胺。当使用时,该(一种或多种)润滑剂一般占该聚合物组合物的约0.05重量%-约1.5重量%,及在一些实施方式中约0.1重量%-约0.5重量%(按重量计算)。
参考以下实施例可更好地理解本发明。
