Studies on novel interacting blends of acrylated poly(ester-amide)s having epoxy residues and vinyl ester of bisphenol-C

Novel unsaturated poly(ester-amide)s (UPEAs) were prepared by the reaction of Bisphenol-F based epoxy resin with bisamic acids. Acrylation of UPEAs were carried out using acryloyl chloride and the products are called Acrylated unsaturated poly(ester-amide)s (AUPEAs). These UPEAs were then treated with acrylol chloride to afford acrylated UPEAs resin (i.e., AUPEAs). Interacting blends of equal proportional AUPEAs and vinyl ester epoxy (VE) resin were prepared. APEAs and AUPEAs were characterized by elemental analysis, molecular weight determined by vapor pressure osmometer, IR spectral study and thermogravimetry. Curing of interacting blends was 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 thermogravimetry (TGA).
