Method for preparing antibacterial PBAT foamed material

Resumen de: GB2641594A

A multistep synthesis of an antimicrobial polybutylene adipate terephthalate (PBAT) material comprising synthesising a monomer, co-polymerisation, mixing with a filler and foaming the co-polymer. The monomer is synthesised by performing a Williamson ether synthesis with 5,5-bis(hydroxymethyl)-2-phenyl-1,3-dioxane and 3-bromo-1-propene followed by hydrolysis of the acetal forming intermediate 2. Intermediate 2 is mixed with 2-methacryloxyethyltrimethylammonium chloride, hexafluorobutyl methacrylate and ammonium persulfate to form a modified monomer. The modified monomer is copolymerised with terephthalic acid, adipic acid, 1,4-butanediol and N-methylpyrrolidone forming a modified co-polymer. The co-polymer is then melted and kneaded with a modified filler and azodicarbonamide under a stable pressure to from a foamed antimicrobial PBAT material. The modified filler is formed by the reaction of p-bromobenzaldehyde, 1,10-phenanthroline-5,6-dione, ammonium acetate, and acetic acid to produce intermediate 3, which is reacted with triisopropyl borate and n-butyllithium to obtain a modifier.
