The reaction of activated esters with epoxides for self-curable, highly flexible, A2B2- and A3B3-type epoxy compounds

Polymer Chemistry, 2019
To achieve high-Tg and low-dissipation epoxy thermosets, bis(2-methoxy-4-(oxiran-2-ylmethyl)phenyl)isophthalate (2) and tris(2-methoxy-4-(oxiran-2-ylmethyl)phenyl)benzene-1,3,5-tricarboxylate (3) were prepared.

Comparative Study on the Properties of Epoxy Derived from Aromatic and Heteroaromatic Compounds: The Role of Hydrogen Bonding

, 2020
Epoxy derived from heteroaromatic compounds and its properties are seldom reported. In this work, two model epoxy monomers (EP-B and EP-F) were synthesized from isophthalic acid and 2,5-furandicarboxylic acid. After curing with 4,4-diaminodiphenylmethane

On the curing kinetics of epoxy/PLA compounds

Journal of Materials Research, 2021
Non-isothermal curing kinetics of DGEBA/PLA/MTHPA compounds was modeled using Ozawa, Kissinger, Friedman autocatalytic, Friedman and Malek models, whose parameters and associate deviation are reported. Ozawa and Kissinger consider global Ea over the whole conversion, estimated as 65.0 kJ/mol with R2 0.8393 and 87.60; these low R2 are due to the several

Reinforcement of epoxy compounds with fillers

Polymer Mechanics, 1972
The mechanical and physicochemical properties of epoxy compounds containing different amounts of a series of fillers have been investigated. The strength characteristics of compounds with reinforcing fillers improve, starting from very low concentrations, pass through a maximum, and then fall at large concentrations.

Self‐curing epoxy compounds

Journal of Applied Polymer Science, 1990
AbstractA new series including eight structurally different self‐curing epoxy compounds bearing azomethine linkages were synthesized, characterized and polymerized. 4‐(2,3‐Epoxypropoxy)‐benzaldehyde (EPB) or 2,3‐epoxypropyl glyoxylate monohydrate (EPG), prepared by reacting 4‐hydroxybenzaldehyde or glyoxylic acid monohydrate, respectively, with excess ...

Thermophysical analysis of plasticized epoxy compounds

Journal of Engineering Physics, 1973
A study has been made concerning the effect of dibutylphthalate and thiocol plasticizers in various concentrations on the structure as well as the thermophysical and the mechanical properties of grade ED-5 epoxy resin. It is shown that the entire complex of analyzed thermophysical properties changes appreciably, depending on the kind and on the ...

Ablation resistance of certain epoxy compounds

Polymer Mechanics, 1972
The rate of ablation in oxidative and inert media at flow velocities up to 200 m/sec has been investigated for certain epoxy compounds containing powdered copper and zinc dust. The causes of ablative destruction and the factors tending to improve the ablation resistance are examined.
