Abstract—Epoxy–anhydride polymers based on N,N,O-triglycidyl-p-aminophenol and isomethyltetrahydrophthalic
anhydride were synthesized in the presence of new active modiﬁ ers, polyﬂ uoroalkyl glycidyl ethers. The kinetics
of the reactions of the modiﬁ ers with the anhydride were studied by differential scanning calorimetry and IR
spectroscopy. The physicomechanical characteristics, glass transition points, and water absorption of the polymers
Epoxy polymers are used as components of
composite materials in rocket and space engineering,
aircraft construction, machine and ship building,
radioelectronics, and building . They have unique
properties: high strength, corrosion resistance, and high
adhesion to various materials.
However, epoxy materials often have poor heat and
water resistance. They absorb up to 8–10% water, which
leads to a drastic decrease in the heat resistance [2, 3].
One of the ways to improve these properties is
introduction of polyﬂ uoroalkyl groups into the structure
of the polymers, which makes the materials more
hydrophobic [4–16]. In so doing, it is important that
the chemical modiﬁ ers should be incorporated in the
polymer matrix in the course of the polymer synthesis
and should not cause phase segregation of the system [4,
5]. Various partially ﬂ uorinated compounds are used for
this purpose [17–19].
