“…Synthesis of Monoallyl Maleate (MAMA). MAMA was synthesized according to methods described in literature data. , Into a 0.5 L four-necked round-bottom flask equipped as above were charged 116 g (1 mol) of AlA, 98 g (1 mol) of MA, and 1.5 g of HQ. The mixture was heated 15 min at 85 °C when an exothermal reaction was initiated.…”

Formaldehyde resins at various molar ratios of monomers (aniline/o-cresol/cyclohexanone) were synthesized under acid catalysis. The resultant resins were reacted with a large excess of epichlorohydrin, and multifunctional epoxy formaldehyde resins were obtained. These resins were reacted with monoallyl ester of maleic acid in the presence of benzyltriethylammonium bromide as catalyst, and multiallyl maleate resins were obtained. The resins were characterized by elemental analysis and by spectroscopic methods (IR and NMR). The curing and decomposition behavior of cross-linked resins were studied by DSC and TGA techniques. The presence of allyl maleate as pendant groups on polymeric chains confers on them the improvement of the possibilities for obtaining thermosetting resin systems based on bismaleimide derivatives. The cross-linked products showed good thermal properties, high glass transitions, and low water absorption.

Vinyl ester resins (VERs) are often described as a cross between unsaturated polyester resins and epoxy resins. VERs offer an upgrade to epoxy resins, and they tend to be selected when chemical and temperature resistance is required. This research was aimed at developing the synthesis of unsaturated ester resins (UERs), which are similar to VERs. UERs were synthesized by the addition of dihydrodicyclopentadienyl hydrogen maleate to the terminal epoxy groups in low-molecular-weight bisphenol A/epichlorohydrin epoxy resins. The effect of urethanization of UERs on the properties of the crosslinked polymer was also investigated. As crosslinking monomers, styrene and glycol dimethacrylates were used. The following properties of cured UERs were determined: the heat deflection temperature, alkali resistance, and the mechanical strength.
