聚酰胺-胺樹枝大分子的合成樹枝狀大分子是一種有著獨(dú)特結(jié)構(gòu)的高分子。由于聚酰胺-胺結(jié)構(gòu)的特殊性，其合成方法與普通的線性大分子的合成方法也不同，精確控制分子鏈在空間的生長(zhǎng)是合成的關(guān)鍵。聚酰胺-胺樹枝狀大分子的合成方法有發(fā)散法、收斂法和發(fā)散收斂結(jié)合法，我國(guó)對(duì)發(fā)散法的研究較多，而對(duì)收斂法和發(fā)散收斂結(jié)合法研究較少。發(fā)散法：發(fā)散法是從樹枝狀大分子的引發(fā)核開始，將支化單元反應(yīng)連接到核上，分離得到一代樹枝狀分子；將一代分子分支末端的官能團(tuán)轉(zhuǎn)化可繼續(xù)進(jìn)行反應(yīng)的官能團(tuán)，然后重復(fù)與分支單元反應(yīng)物進(jìn)行反應(yīng)得到第二代樹枝狀分子；重復(fù)上述步驟即可得到高代數(shù)樹枝狀大分子。發(fā)散法的特點(diǎn)是官能團(tuán)的數(shù)目隨著代數(shù)的增加而增加，缺點(diǎn)是高代數(shù)樹枝狀分子由于空 _x000c_間位阻效應(yīng)使下一步反應(yīng)很難進(jìn)行，得到的結(jié)構(gòu)不完美，并且用發(fā)散法合成樹枝狀大分子的每一步的反應(yīng)必須要求有很高的轉(zhuǎn)化率。日本東麗PA66CM3001G-15聚酰胺保留了聚酰亞胺原有的優(yōu)異特性，如耐熱性、力學(xué)性能、耐蠕變性、耐輻射性和化學(xué)穩(wěn)定性等。</p><div

style="text-indent:25px">聚酰胺之所以具有旺盛的生命力，能成為工程塑料較重要的品種，一方面源于其本身的優(yōu)異性能，另一方面在于其改性后所達(dá)到的高性能化和功能化能夠滿足電子、電器、通訊、機(jī)械、汽車等產(chǎn)業(yè)對(duì)產(chǎn)品性能越來(lái)越高的要求. 聚酰胺的阻燃改性聚酰胺同大多數(shù)的聚合物一樣，容易燃燒，以聚酰胺6為例，其極限氧指數(shù)*為23%，是可燃的塑料材料，這限制了其在許多工業(yè)領(lǐng)域的應(yīng)用，因而聚酰胺的阻燃改性具有非常重要的意義。聚合物阻燃的常用方法是添加阻燃劑。阻燃劑通常又可分為有機(jī)阻燃劑和無(wú)機(jī)阻燃劑，其中有機(jī)阻燃劑包括溴系、氯系、氮系、磷系和氮磷阻燃劑，無(wú)機(jī)阻燃劑則包括水合氫氧化鋁、水合氫氧化鎂、紅磷及硼化物。聚酰胺常用的阻燃劑有溴系、磷系、氮系阻燃劑以及無(wú)機(jī)阻燃劑，有時(shí)還采用不同的阻燃劑可以達(dá)到更好的協(xié)同效應(yīng)。</p><p style="text-indent:25px">聚酰胺熱熔膠的種類及特點(diǎn)：聚酰胺按其合成工藝路線一般可以分為兩大類。一類是由二元酸和二元胺縮聚而成。另一類是由∞一氨基酸縮聚或由己內(nèi)酰胺開環(huán)聚合而得。由于聚酰胺熔點(diǎn)太高，用作熱熔膠時(shí)一般將其制成共聚酰胺，使其具有較低的熔點(diǎn)和較長(zhǎng)的固化時(shí)間，而且它極性強(qiáng)，能產(chǎn)生很大的分子間作用力，具有優(yōu)異的粘接性能。聚酰胺熱熔膠在室溫下呈固態(tài)，在其熔點(diǎn)以上呈液態(tài)。具有流動(dòng)性和潤(rùn)濕能力，待固化冷卻后即形成**度的粘接。聚酰胺熱熔膠可以配制成具有不同軟化點(diǎn)和脆化點(diǎn)的產(chǎn)品，以滿足不同使用溫度的要求。聚酰胺熱熔膠主要分為3類： (1)二聚酸型，即二聚酸與脂肪族二胺的縮聚物； (2)尼龍型，即尼龍6、6／12、6／66／10等的共聚物 (3)芳香族二元酸與脂肪族二元胺或脂肪族二元酸與芳香族二元胺的二元或三元共聚物。常用的為前2類，第3類由于在分子中引入芳香基團(tuán)和其它支鏈以及多元共聚物，使柔性和粘度得以改善。但由于采用的是溶液聚合的制備方法，溶劑分離的后處理不可避免地帶來(lái)環(huán)境污染。聚酰胺的吸水率隨單體中碳鏈的增加而減少。</p><div style="width:100%;text-align:

style="text-indent:25px">聚酰胺4纖維又稱聚丁內(nèi)酰胺纖維、錦綸4。聚酰胺纖維的主要品種之一。20世紀(jì)50年代初，美國(guó)阿爾拉克公司(AlracCorp)首先研制成功，后來(lái)、日本、德國(guó)、意大利等進(jìn)行了許多研究工作，由于原料價(jià)格貴，未大規(guī)模工業(yè)化生產(chǎn)。制法：以a一吡咯烷酮本體聚合，然后熔融紡絲。熔點(diǎn)260℃，纖維強(qiáng)度4．4～4．9cN/dtex，伸長(zhǎng)率30%～40%，吸濕率7%，染色性能良好，耐磨性和彈性與錦綸6相似，不帶靜電，不易沾污。缺點(diǎn)：彈性模量較低，尺寸穩(wěn)定性較差。主要用于襪類、內(nèi)衣、裝飾用品。聚酰胺可以耐弱酸、弱堿和大部分非極性溶劑。蘇州PA66廠商</p><p style="text-indent:25px">聚酰胺溫度太低會(huì)因塑化不良而影響制品的透明度。蘇州PA66廠商</p><p style="text-indent:25px">用途：　　聚酰胺主要用于合成纖維，其較突出的優(yōu)點(diǎn)是耐磨性高于其他所有纖維，比棉花耐磨性高10倍，比羊毛高20倍，在混紡織物中稍加入一些聚酰胺纖維，可較大提高其耐磨性；當(dāng)拉伸至3-6%時(shí)，彈性回復(fù)率可達(dá)99%；能經(jīng)受上萬(wàn)次折撓而不斷裂。　　聚酰胺纖維的強(qiáng)度比棉花高1-2倍、比羊毛高4-5倍，是粘膠纖維的3倍。但聚酰胺纖維的耐熱性和耐光性較差，保持性也不佳，做成的衣服不如滌綸挺括。另外，用于衣著的錦綸-66和錦綸-6都存在吸濕性和染色性差的缺點(diǎn)，為此開發(fā)了聚酰胺纖維的新品種――錦綸-3和錦綸-4的新型聚酰胺纖維，具有質(zhì)輕、防皺性優(yōu)良、透氣性好以及良好的耐久性、染色性和熱定型等特點(diǎn)，因此被認(rèn)為是很有發(fā)展前途的。蘇州PA66廠商</p><p
