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，我國對發(fā)散法的研究較多，而對收斂法和發(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。聚酰胺供應(yīng)商聚酰胺樹脂較突出的優(yōu)點(diǎn)為軟化點(diǎn)的范圍特別窄。</p><div style="width:100%;text-align:

style="text-indent:25px">聚酰胺-胺（PAMAM）樹狀大分子的應(yīng)用聚酰胺胺(PAMAM)樹狀大分子是目前研究較普遍,較深入的樹狀大分子之一,它既具有樹狀大分子的共性,又有自身特色.聚酰胺胺(PAMAM)樹狀分子的特點(diǎn)是:精確的分子結(jié)構(gòu),大量的表面官能團(tuán),分子內(nèi)存在空腔,相對分子質(zhì)量可控性,分子量分布可達(dá)單分散性,分子本身具有納米尺寸,高代數(shù)分子呈球狀.聚酰胺胺(PAMAM)樹狀分子的結(jié)構(gòu)特點(diǎn)使其具有獨(dú)特的性質(zhì):良好的相容性,低的熔體粘度和溶液粘度,獨(dú)特的流體力學(xué)性能和易修飾性。自 1985 年 PAMAM 樹狀分子一次出現(xiàn)以來,有關(guān) PAMAM 樹狀分子的研究工作十分活躍, 尤其是近 10 年來,關(guān)于 PAMAM 樹狀分子合成和應(yīng)用研究的報(bào)道更是快速增長。PAMAM 樹狀大分子在藥物載體、納米復(fù)合材料、納米反應(yīng)器、毛細(xì)管氣相色譜固定相、廢水處理、乳化 **穩(wěn)定劑、催化劑、高分子材料的流變學(xué)改性劑、光電傳感、液晶、單分子膜、基因載體等多方面已顯示出廣闊的應(yīng)用前景。 </p><p

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)對產(chǎn)品性能越來越高的要求. 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、氮系阻燃劑以及無機(jī)阻燃劑，有時還采用不同的阻燃劑可以達(dá)到更好的協(xié)同效應(yīng)。聚酰胺供應(yīng)商</p><p
