摘　　要：以歧化松香为原料,先制得脱氢枞胺,再与丙烯酰氯经酰胺化反应合成了N-脱氢枞基丙烯酰胺单体,经提纯为液相色谱纯度97.95%的白色固体。通过FT-IR、MS、~1H NMR、^(13)C NMR、TG、GPC及DSC表征了其结构和性能。结构表征结果显示成功合成了N-脱氢枞基丙烯酰胺。DSC分析显示,单一单体在151~196℃时发生热聚合,且自由基引发剂偶氮二异丁腈(AIBN)的存在可以降低其聚合温度,聚合物的玻璃化转变温度在100.34℃。TG分析显示,聚合物在209~483℃发生热分解。对N-脱氢枞基丙烯酰胺聚合物进行GPC分析,结果为M_n=4 301,M_w/M_n=1.56。N-dehydroabietic acrylamide,a polymerization monomer,was synthesized via amidation reaction of acryloyl chloride and dehydroabietylamine which was synthesized using disproportionated rosin as raw materials. And the product was white solid with liquid chromatographic purity of 97. 95 % after purification. The structure and performance of N-dehydroabietic acrylamide monomer were characterized by FT-IR,MS,^1H NMR,^13C NMR,TG,DSC and GPC. The characterization results showed that Ndehydroabietic acrylamide was synthesized successfully. The DSC analysis showed that the thermal polymerization of the single monomer was occurred during 151-196 ℃,the glass transition temperature of the polymer was 100. 34 ℃ and the polymerization temperature could be reduced with the presence of free radical initiator azodiisobutyronitrile（ AIBN）. The TG analysis showed that the thermal decomposition of the polymer occurred at 209-483 ℃. The Mnof homopolymer of N-dehydroabietic acrylamide polymerization was 4301 and Mw/ Mn was 1. 56 from the GPC analysis.
