The synthesis and properties of the new epoxyfumarate and epoxymaleate resins obtained by the addition of acidic allyl maleate to the commercially available resin Epidian 5 are presented. The resins were synthesized in one‐ and two‐step procedures and properties of the obtained resins are compared. It should be noted that the use of allyl alcohol in the synthesis of unsaturated resins has an advantageous influence on their properties. Glass‐transition temperatures of the epoxyfumarate resins exceed 100°C, whereas those of epoxymaleates are higher than 70°C. The resins are also characterized by good chemical resistance. © 2002 John Wiley & Sons, Inc. J Appl Polym Sci 84: 716–722, 2002; DOI 10.1002/app.10067 相似文献

Synthesis and properties of epoxyfumarate and epoxymaleate resins obtained by the addition of acidic ester of maleic acid to the commercially available resin, Epidian 5, is presented. In acidic ester preparation, n‐hexanol was used. The resins were synthesized in one‐ and two‐step procedures. In the two‐step procedure, acidic hexyl maleate was synthesized separately and then used for the addition reaction with epoxy resin. In the one‐step synthesis, acidic ester was formed during the synthesis process. Properties of the obtained resins were compared. © 2000 John Wiley & Sons, Inc.
