Description
Summary:Bisphthalamic acids were prepared by reactions of phthalic anhydride and aromatic diamines. Novel flame-retardant poly(ester-amide) resins (FR-PEAs) were prepared by reactions of brominated epoxy resin (BER) with bisphthalamic acids using a base catalyst. The post reactions of these FR-PEAs were carried out with acryloyl chloride. The resultant products are designated as flame-retardant acrylated poly(ester-amide)s (FR-APEAs). The FR-PEAs and FR-APEAs were characterized by element analysis and number average molecular weight determined by nonaqueous conductometric titration. IR spectra for FR-PEAs and FR-APEAs were also carried out. The curing of these FR-APEAs was monitored on a differential scanning calorimeter (DSC) by using benzoyl peroxide as a catalyst. Glass fiber-reinforced composites of FR-APEAs have been fabricated and their chemical, mechanical, electrical and flame-retardant properties have been evaluated. The unreinforced cured samples of FR-APEAs were analyzed thermogravimetrically.
