含Zr聚乙炔基苯胺树脂的制备

Synthesis of Zirconium-Aminophenylacetylene Resin

以四氯化锆、苯乙炔和间乙炔基苯胺(APA)为原料,通过先驱体合成法制备新型含锆有机先驱体树脂——含Zr聚乙炔基苯胺树脂(ZAPA)。通过FT-IR表征了其结构,利用DSC及FT-IR研究了其固化反应,通过TG研究了其固化物的耐热性能,采用XRD和EDS研究了其固化物的烧结性能。结果表明:ZAPA树脂可以发生固化交联反应,其固化物相对于APA的固化物具有更好的耐热性能,在N2气氛下,ZAPA树脂固化物失重5%的温度为445°C,1 000°C下的质量残余率为43.7%;在空气气氛中,1 000°C下烧结5h后,可形成ZrO2晶体。

Nanocolorants were prepared by miniemulsion polymerization with sodiumα-olefin sulfonate（AOS）as polymerizable emulsifier,styrene（St）as monomer,methyl methacrylate（MMA）as polar monomer,divinylbenzene（DVB）as crosslinking agent,hexadecane（HD）as co-stabilizer.Transmission Electron Microscopy（TEM）and Dynamic Laser Light Scattering（DLS）were used to study the effects of the amount of AOS,polar monomer and crosslinker on the morphology of nanocolorants.Results showed that the average particle size of nanocolorants decreased with the increasing of the amount of AOS.Appropriate amount of polar monomer was helpful to produce the core-shell particles with narrow particle size distribution.The difference of polarity between monomer and crosslinker led to the rough surface of nanocolorants.When St was used as monomer,the nanocolorants appeared crumpled surface as the mass of DVB relative to St was higher than 30%.However,for MMA,the nanocolorants appeared serious crumpled surface when the mass of DVB relative to MMA was in the range of 8%—30%.
