| 摘 要： | 采用HDI缩二脲封端端羟基丁腈橡胶预聚物,制备大分子橡胶改性活化剂,以氢氧化钠为催化剂,选择不同配比的ABS树脂加入熔融己内酰胺单体中,确定聚合温度为160℃~180℃,通过阴离子聚合制得ABS/PA6共混物。耐水性和吸水后力学性能分析得知,合金共聚物吸水率比纯PA6明显降低,合金吸水后力学性能有不同程度的降低,但吸水后力学损失量比纯PA6低很多。电镜测试表明原位反应增容因PA6与ABS两相界面张力降低,使ABS分散颗粒变小并更均匀地分散于PA6中。 |

| Abstract: | Macromolecule modification activator was prepared using prepolymer of HTBN end capped by HDI biuret(N-75).Then the ABS/PA6 co-blend polymer was prepared by anionic polymerization with putting ABS resin into molten caprolactam monomer at the temperature of 160 ℃～180 ℃ and the sodium hydroxide being used as activator.Compared with PA6,the copolymer alloy shows obviously low water absorption and slightly reducing mechanical property after absorption,while the loss of mechanical property is lower.The SEM analysis reveals that the reaction insitu compatibilization reduces the interfacial tension between PA6 and ABS and makes the ABS grain smaller and more uniform dispersion in PA6. |
