Abstract

Three azido-terminated poly(ethylene glycol) macromonomers (ATPEGs) were synthesized from poly(ethylene glycol)s (PEGs) and characterized. The extended polytriazole (EPTA) resins were prepared from the macromonomers, azide and alkyne monomers. Toughening effect of PEGs on polytriazole resins was analyzed by means of mechanical, thermal and electronic microscope characterization. The results show that molecular weight and content of ATPEGs have great influence on the thermal and mechanical properties of cured EPTA resins. The impact strength of cured EPTA resins increases with the increase of the amount and molecular weight of ATPEGs. The flexural strength and heat resistance of cured EPTA resins decrease with the increase of addition amount and molecular weight of ATPEGs. High impact EPTA resins were obtained.

用于高级复合材料的高冲击聚三唑树脂。

以聚乙二醇(peg)为原料合成了3个端叠氮基团的聚乙二醇大单体(atpeg)，并对其进行了表征。以大型单体、叠氮化物和炔类单体为原料制备了扩展聚三唑树脂。采用力学、热、电镜等表征方法分析了聚乙二醇对聚三唑树脂的增韧作用。结果表明，atpeg的分子量和含量对EPTA树脂固化后的热性能和力学性能有较大影响。随着atpeg用量的增加和分子量的增加，固化EPTA树脂的冲击强度增大。随着atpeg的加入量和分子量的增加，EPTA树脂的抗弯强度和耐热性降低。获得了高冲击EPTA树脂。

期刊介绍： Designed Monomers and Polymers ( DMP) publishes prompt peer-reviewed papers and short topical reviews on all areas of macromolecular design and applications. Emphasis is placed on the preparations of new monomers, including characterization and applications. Experiments should be presented in sufficient detail (including specific observations, precautionary notes, use of new materials, techniques, and their possible problems) that they could be reproduced by any researcher wishing to repeat the work. The journal also includes macromolecular design of polymeric materials (such as polymeric biomaterials, biomedical polymers, etc.) with medical applications. DMP provides an interface between organic and polymer chemistries and aims to bridge the gap between monomer synthesis and the design of new polymers. Submssions are invited in the areas including, but not limited to: -macromolecular science, initiators, macroinitiators for macromolecular design -kinetics, mechanism and modelling aspects of polymerization -new methods of synthesis of known monomers -new monomers (must show evidence for polymerization, e.g. polycondensation, sequential combination, oxidative coupling, radiation, plasma polymerization) -functional prepolymers of various architectures such as hyperbranched polymers, telechelic polymers, macromonomers, or dendrimers -new polymeric materials with biomedical applications
