La polyesterification de l'anhydride maleique avec l'ethylene glycol catalysee par l'acide p-toluene sulfonique dans des conditions tres controlees donne un polyester lineaire insature de MN elevee. L'isomerisation cis-trans dans le milieu semble le principal obstacle a l'obtention de polymeres de MN plus ...

The polymerization of maleic anhydride and 1,3-propylene glycol was carried out using p-toluenesulphonic acid as catalyst. The percentage isomerization of maleate to fumarate has been correlated with the extension of polycondensation and the steric hindrance between the condensed functional ...

Photocrosslinkable unsaturated polyesters
Journal of Applied Polymer Science, 1979AbstractNine photocrosslinkable unsaturated polyesters containing pendent chalconyl and cinnamylidenemalonyl moieties have been synthesized by a route involving no water elimination. The resins are insolubilized by visible and UV irradiation. They can also be cured with styrene, MEK peroxide, and cobalt naphthenate.

AbstractHighly crosslinkable unsaturated polyester resins (UPR) have attracted many interests in the application as reinforced matrix materials. Here, we present a systematical study of the influence of different curing conditions and styrene concentrations on resin viscosity and dynamic‐mechanical properties of the thermoset. The pure maleic Palapreg®

Unsaturated Polyesters and Vinyl Esters
2014Unsaturated polyester resins (UPR) and vinyl ester resins (VER) are among the most commercially important thermosetting matrix materials for composites. Although comparatively low cost, their technological performance is suitable for a wide range of applications, such as fiber-reinforced plastics, artificial marble or onyx, polymer concrete, or gel ...

Polyesters ofω-Unsaturated Fatty Acid Derivatives
Macromolecular Chemistry and Physics, 2001Unsaturated polyesters, based on ω-unsaturated fatty acid esters from oleochemical resources and petrochemical diols, were synthesized via two different synthetic pathways. 9-decenoic and 10-undecenoic acid methyl ester Ia, b were transesterified with petrochemical diols to produce the a,ω-alkylene di(un)decenoates IIa-d, which were subsequently ...

The unsaturated polyester resins used in reinforced plastics (RP) are combinations of reactive polymers and reactive monomers. The idea for this combination was introduced by Carleton Ellis in the 1930’s. Ellis discovered that unsaturated polyester resins made by reacting glycols with maleic anhydride could be cured to insoluble solids simply by adding
