Interacting blends of Styrenated unsaturated poly (ester–amide)‎ s with commercial unsaturated polyester resin (o-phthalic anhydride based)‎

الملخص EN

Unsaturated poly (ester–amide) s resins (UPEAs) were prepared by the reaction between an epoxy resin, namely diglycidyl ether of bisphenol-A (DGEBA) and unsaturated aliphatic bisamic acids (B1–4) using a base catalyst.

These UPEAs were then diluted by styrene and blended with commercial unsaturated polyester resin (o-phthalic anhydride based) to produce a homogeneous resin.

The curing of these Styrenated UPEAs–UPR blends was carried out using Benzoyl peroxide (BPO) as a catalyst and N, N0-Dimethyl aniline (DMA) as a promoter.

The glass fiber reinforced composites (i.

e.

laminates) of these Styrenated UPEAs–UPR (o-phthalic anhydride based) blends were fabricated.

The mechanical and chemical resistance properties of the glass fiber composites have also been evaluated.

The unreinforced cured samples of the Styrenated UPEAs–UPR (o-phthalic anhydride based) blends were also analyzed by thermogravimetry (TGA).
