摘要：以脱氢枞酸、3-二甲氨基丙胺为原料通过酰胺化反应制备了N-(3-二甲氨基)丙基-脱氢枞酸酰胺(DHADA),然后再和3-溴丙醇丙烯酸酯经过季铵化反应合成了水溶性松香可聚合单体(3-丙烯酰氧基)丙基(3-脱氢枞酰胺)丙基二甲基溴化铵(DHA-DA-Br)。使用核磁共振(NMR)、红外光谱(FT-IR)、质谱(MS)等对其进行结构表征,利用差示扫描量热仪(DSC)对其聚合行为进行研究,采用表面张力仪对其表面张力(γ_(CMC))、临界胶束浓度(CMC)进行测定。结果表明:试验成功合成了水溶性松香可聚合松香基单体DHA-DA-Br;DHA-DA-Br单体可发生自聚反应(DSC最大放热峰为131℃),在引发剂偶氮二异丁腈作用下,反应温度明显降低(DSC最大放热峰为112℃);DHA-DA-Br水溶液在25℃时CMC为0.003 2 mol/L,此时单体水溶液的γ_(CMC)值为35 mN/m。DHADA-Br在制备或改性水溶性聚合物领域具有较好应用前景。
Rosin, which consists primarily of 90% rosin acids and 10% neutral compounds, is one of the most impor-tant forest products in China. Rosin-based derivatives can be used as additives to lower the glass transition temperature and improve the mechanical properties of polymers such as epoxy resin, coating and polyamide. However, the synthe-sis of water-soluble rosin-based derivatives is rarely reported. In this study, a water-soluble rosin-based monomer was prepared and characterized. First, the N-（3-dimethylamino） propyl-dehydroabietic acid （DHA-DA） was prepared from dehydroabietic acid and 3-dimethylaminopropylamine by amidation reaction; and then the water-soluble rosin-based monomer 3-(acryloyloxy)-N-(3-(dehydroabietyl-l-carboxamido)-N, N-dimethylpropan-l-aminium bromide （DHA-DA-Br） was synthesized by 3-bromopropyl acrylate and DHA-DA via quatemization reaction. The structure of DHA-DA-Br was characterized by nuclear magnetic resonance （NMR）, mass spectrometry （MS） and Fourier trans-form infrared spectoscopy （FT-IR）. The polymerization behavior was investigated by differential scanning calorimeter （DSC）. Surface tension (γCMC) and critical micelle concentration （CMC） were measured by surface tension meter. The results indicated that the water-soluble rosin-based monomer DHA-DA-Br was successfully synthesized; when used 2, 2＇-azobis （2-methylpropionitrile） （AIBN） as the initiator, the obtained rosin-based monomer exhibited a lower polymerization temperature (DSC exothermic peak was 112℃） than the polymerization temperature of pure wa-ter-soluble rosin-based monomer （DSC exothemaic peak was 131℃) did; and the CMC values of rosin-based mono-mer solution was 0.003 2 mol/L at 25℃, and the γCMC was 35 mN/m. The synthesized rosin-based monomer DHA-DA-Br has a great potential for preparation or modification of water-soluble polymer.
