New polymeric coating compositions

Arious Modified Polyesteramide Varnishes as Antimicrobial Surface Coating Vehicles.

“…Polyesteramide resins containing pentachlorophenol residue in their structure were prepared and evaluated as antimicrobial growth control [6]. Another polyesteramide resins were prepared containing a stoichiometric amount of 8hydroxquinoline as preservative against micobiolgical attack [7].The other modified polyesteramide resins were prepared in which stoichiometric amount of hydroxyethyl fatty acid amides are replaced by nicotinic and isonicotinic acids derivatives of diethanolamine and triethanolamine.…”

Catalytic polymerization of N,N-diethanol acrylamide with phthalic anhydride in the presence of H-mordenite and Fe-mordenite zeolites

“…The formation of 100% amide in the absence of any catalyst and in presence of some oxide catalysts such as Fe 2 O 3 and TiO 2 ; as has been evidenced by some authors [1][2][3][4][5][6], provokes the importance of the unshared electron pair on the amine nitrogen; which can be shared with electron deficient carbonyl group. Such unshared pair on nitrogen is less tightly held than that on the corresponding oxygen atom of alcohol based on electronegativity consideration.…”

“…The diol formation was performed by reacting diethanolamine (DEA) and acrylic acid in the presence of the latter catalyst in addition to Fe-mordenites using o-xylene as a solvent (bp 140 • C). The diol (DEAA) was the major product produced according to the expected strong interaction of the amine (DEA) with the carboxyl group of the acid [3][4][5][6]. This reaction was followed up by monitoring the amount of water liberated.…”

“…The reaction proceeds to completion in forming DEAA and DEMA with selectivities 91 and 9%, respectively. It is noteworthy mentioning that the majority of the work used to prepare dihydric amino alcohol derivatives of fatty acids claimed the absence of the ester formation [1][2][3][4][5][6].…”

“…Diethanolamine derivatives of fatty acids were used in the preparation of polyesteramide and alkyd/polyesteramide resins [3,4]. Most alkylolamides are derived from ethanolamine and fatty acids [5,6]. The above-mentioned derivatives are used as the ingredient source of dihydric alcohol for polycondensation.…”
