摘要:由油酸二聚酸(ODA)、聚合松香(PR)、乙二胺(EDA)经缩聚反应得到低相对分子质量端羧基聚酰胺树脂(CLMPA),而后再与己二酸(AA)、环氧树脂(E-51)开环聚合反应得多羟基聚酰胺树脂(PHPA),最后与甲基四氢苯酐(Me-THPA)酯化,得到多羧基聚酰胺树脂(PCPA),中和成盐,得阴离子型水性聚酰胺树脂(AWPA)。通过考察目标产物水溶性、涂膜的耐水性、相对分子质量(Mr)、黏度及玻璃化转变温度(Tg)研究了PR和ODA的物质的量之比(PR/ODA)、CLMPA和AA的物质的量之比(CLMPA/AA)对AWPA性能的影响,并通过红外光谱和核磁共振氢谱对各中间体及目标产物进行了表征。结果表明:当PR/ODA为4∶6、CLMPA/AA为2∶10时,合成的聚酰胺树脂溶于水,Mr7 264,吸水率27.6%,黏度42.3 Pa.s(100℃),Tg 47.15℃。
Carboxyl-terminated and low-molecular weight polyamide (CLMPA)was synthesized from polycondensation reaction among oleie dimeric acid ( ODA ), polymerized rosin (PR) and 1,2 -ethylenediamine ( EDA ). Polyhydroxy polyamide ( PHPA ) was obtained by ring-opening polymerization among adipic acid (AA), epoxy-51 (E-51)and CLMPA. Polycaoboxylic polyamide (PCPA) was synthesized by esterification of PHPA with methyltetrahydrophthalic anhydride (Me-THPA), and anionic water- soluble polyamide resin(AWPA) was obtained by means of salt-formation from neutralization. The effects of PR/ODA, CLMPA./ AA on the properties of the water-soluble polyamide such as water solubility, water resistance, relative molecular mass ( Mr ), viseosity and glass transition temperature( Tg )were investigated. The structures of the intermediates and the target product were characterized by FT-IR and 1H NMR. The results showed that the optimum molar ratios were as followed: molar ratio of PR to ODA was 4:6, molar ratio of CLMPA to AA was 2: 10, the polyamide resin was water soluble, with Mr 7 264, water absorption 27.6%, viscosity 42.3 Pa.s(100 %) and Tg 47. 15 ℃.
