Interacting blends of acrylated poly(ester-amide)s containing epoxy residues with vinyl ester resin

Unsaturated bisamic acids were prepared by reaction between maleic anhydride and different aliphatic di-amines. Unsaturated poly(ester-amide) resin (UPEAs) were prepared by reaction of diglycidyl ether of bisphenol-A (DGEBA) with unsaturated bisamic acids derived from. Acrylation of UPEAs was carried out to afford acrylated UPEAs resin (i.e. AUPEAs). Interacting blends of AUPEAs with vinyl ester epoxy (VE) resin was prepared. APEAs and AUPEAs were characterized by elemental analysis, molecular weight determined by vapour pressure osmometer and by IR spectral study and by thermogravimetry. The curing of interacting blends were monitored on differential scanning calorimeter (DSC). Based on DSC data in situ glass reinforced composites of the resultant blends have been prepared and characterized for mechanical, electrical and chemical properties. Unreinforced blends were characterized by thermogravimetrically (TGA).
