Water absorption and thermomechanical properties of epoxy systems based on multifunctional dicyclopentadiene epoxy novolac resin Tactix556 cured with 4,4Ј diaminodiphenilsulfone (4,4ЈDDS) as curing agent has been studied. The base system was modified by the addition of a novel 40 : 60 PES : PEES (Polyethersulphone : Polyetheretheresulphone) amine-ended copolymer to improve toughness properties. The effect of thermoplastic addition on water adsorption was studied by gravimetric experiments. The viscoelastic properties of the resulting blend were analyzed by means of dynamic mechanical thermal analysis. The formulated systems were compared with a system based on tetraglycidyl-4,4Јdiaminodiphenylmethane resin (MY721) cured with 4,4Ј diaminodiphenilsulfone. The use of Tactix556 resin showed that water uptake values were minimized while retaining high glass transition temperatures, and toughness values were found in the same range of standard toughened matrices used for aerospace composites.

“…These properties include high stability against hydrolysis, high thermal stability, high stability against oxidation and UV light, low inflammability, high glass‐transition temperatures, and good transparency when the PESs are amorphous. To vary their properties and broaden their applications, numerous research groups have synthesized functionalized PESs either by direct synthesis from functionalized monomers1–7 or by derivatization of preformed (commercial) PESs 8–17. A third approach consists of the preparation of star‐shaped or hyperbranched PESs 18, 19.…”

Branched poly(ether sulfone)s were prepared from 1,1,1‐tris(4‐hydroxyphenyl) ethane and 4,4′‐difluorodiphenyl sulfone (DFDPS) either by polycondensation in dimethyl sulfoxide with the elimination of water or via the silyl method in N‐methylpyrrolidone. With an exact 1/1 stoichiometry, crosslinking was avoidable, but significant fractions of cyclic oligomers and polymers were detected by matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry. Furthermore, bridged cycles (bicycles) were detected. For the silyl method, even an excess of DFDPS of 10 mol % did not result in crosslinking. The pendant OH groups were modified by acylation with acetic anhydride, methacrylic anhydride, undecylenoyl chloride, or cinnamoyl chloride. Alkylation was only successful in a one‐pot procedure via the silyl method. Alkylbromide, ethyl bromoacetate, 3‐chloropropionitrile, 4‐nitrobenzyl bromide, and 3,4‐dichlorobenzyl chloride served as alkylating agents. With 1,3‐propane and 1,4‐butane sultone, poly(ether sulfone)s with pendant sulfonate groups were obtained. © 2002 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 40: 2967–2978, 2002

“…The functionality can be introduced prior [2][3][4][5][6] to or post [7][8][9][10][11] polymerization. A drawback Poly(arylene ether sulfone)s such as Udel resin, to the introduction of pendant reaction sites prior are useful thermoplastics characterized by good to polymerization is the possibility of undesired thermooxidative stability, high glass transition side reactions during the formation of the polymer temperatures, and good mechanical strength.…”

A versatile approach for the functionalization of a bisphenolic monomer, 3,8‐bis(4‐hydroxyphenyl)‐N‐phenyl‐1,2‐naphthalimide (1) as well as its corresponding poly(N‐phenyl imido aryl ether sulphone) via transimidization reactions with hydrazine monohydrate, aliphatic amines, and an amino acid (11‐amino undecanoic acid) is reported. The reactions proceeded in high conversion and high isolated yield to the desired novel functionalized monomers or polymers with N‐amino, N‐aliphatic, and N‐aliphatic acid pendant groups. The N‐amino functionalized monomer, 2, was reacted cleanly with naphthalic anhydride to form a bisimide. Polymers with phthalimide (7), 3‐carboxy phthalimide (9), and bisphenol‐A‐(monoimide monoanhydride) (8) pendant groups were also formed by imidization of 6. A polymer with a cyclopropyl amide functional group, 10, was formed by reacting 6 with cyclopropyl carbonyl chloride. A brief description of the transimidization reactions and the properties of the functionalized polymers is included. © 1997 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 35: 1095–1108, 1997
