Figure (2) illustrated the infrared spectrum of unsaturated polyester
. The presence of symmetric (C=O) stretching was confirmed by the presence of strong bend at (1721.04) [cm.sup.-1], this band confirms the presence of (C=O) ester group and also confirms the formation of unsaturated polyester
The curing of unsaturated polyester
resins (UPR) proceeds via free radical polymerization between the unsaturated polyester
molecules and a vinyl monomer such as styrene.
The curing process of unsaturated polyester
resin initiated with benzoyl peroxide was studied by differential scanning calorimetry (DSC).

"Evaluation of mechanical properties of unsaturated polyester
guar gum/hydoxypropyl guar gum composites".
Ortho-phthalic general purpose unsaturated polyester
(Neoxil C-92 N 8 from Camelyaf, Turkey) was used as the matrix.
When traditional unsaturated polyester
resins were first used in fiber-reinforced materials, their applications were limited by a number of problems, the most important being poor surface quality.
