“…Epoxy resin‐based materials have been widely used in engineering construction, electronics industry, and other fields, 1–4 due to its excellent adhesion, wettability, dimensional stability, electrical insulation, and chemical resistance 5 . Nevertheless, the application of traditional epoxy resin products is limited due to its inherent high brittleness, poor crack resistance, and weak impact resistance 6 .…”

Achieving synergetic improvements of mechanical strength, toughness, and thermal stability of epoxy resin has been a crucial but very challenging issue. Herein, to explore a new solution for circumventing this issue, polyimide microspheres were successfully prepared through the inverse nonaqueous emulsion process, and the structure, size distribution and morphologies of polyimide (PI) microspheres were comprehensively investigated. Then the PI microspheres were incorporated in epoxy resin matrix to systematically investigate the mechanical and thermal properties of obtained epoxy/PI microspheres composites. It was found that the PI microspheres can not only enhance the mechanical strength of epoxy resin, but also significantly improve the toughness. Specially, the epoxy‐based composites containing 3 wt% PI microspheres exhibit a 47% increase in tensile strength, while the GIC and Charpy impact strength increase by 106% and 200%, respectively. The toughing mechanism of epoxy/PI microspheres composites was discussed. Moreover, the PI microspheres can also endow the epoxy resin with excellent thermal stability and heat resistance. Thus, this work may open a new opportunity to synergistically enhance the mechanical and thermal properties of epoxy‐based composites and may also give some valuable inspiration for the rational design of other high‐performance thermosetting composites.

Usually, the reinforcing effect of carbon nanotubes (CNTs) in a polymer is related to the properties of the matrix and its dispersion in the matrix. In this paper, the modification effect of CNTs on high performance tetraglycidyl ether 1.1.2.2-tetraphenyl ethane epoxy resin (TGETPE) was studied. CNTs grafted with amino groups (N-CNTs) were used to react with DGEBA to form a well dispersed CNTs / epoxy resin mixture (E-CNTs), and then E-CNTs were added to TGETPE/methyl tetrahydrophthalic anhydride (MeTHPA) to form a E-CNTs-reinforced TGETPE composites. The effect of different content of E-CNTs on TGETPE/MeTHPA cured resin was studied. With an increase in content of E-CNTs, the mechanical properties of the cured sample first increase and then decrease. At E-CNT contents of 0.4 and 0.6 wt%, the tensile strength and bending strength of the composites increased by 39% and 34%, respectively. Young's modulus of the cured composite increases with the addition of E-CNTs. In addition, the addition of E-CNTs can improve the thermal properties of the cured sample.

The copolymers of 2,3-Dichloropropene with vinyl chloride, methyl methacrylate, and styrene of different compositions were obtained via free-radical copolymerization. The copolymerization constants for the comonomers were found from the dependence of the copolymer composition on the initial mixture content. An increase in the content of 2,3-Dichloropropene in the initial mixture was found to decrease the yield and intrinsic viscosity of the copolymer for all systems. The reactivity of 2,3-Dichloropropene in copolymerization reactions was assessed according to the reciprocals of the copolymerization constants of vinyl chloride, methyl methacrylate, and styrene, which indicate the reactivity of the dichlorinated monomer when interacting with comonomer radicals. It was found that 2,3-dichloropropene is the most active in the reaction with a styrene radical. However, its reactivity with a methyl methacrylate radical decreases by a factor of 0.88 as compared to the styrene radical. The lowest reactivity of 2,3-Dichloropropene is observed when interacting with a vinyl chloride radical. The synthesized copolymers can be further modified by replacing chlorine atoms with functional groups.
