Interacting blends of Styrenated unsaturated poly (ester–amide)s with commercial unsaturated polyester resin (o-phthalic anhydride based)
2014
Abstract 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 ( B 1 – 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,N′-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).
