Data on synthesis of oligomeric and polymeric poly(butylene adipate-co-butylene terephthalate) model substrates for the investigation of enzymatic hydrolysis

Abstract The aliphatic-aromatic copolyester poly(butylene adipate-co-butylene terephthalate) (PBAT), also known as ecoflex, contains adipic acid, 1,4-butanediol and terephthalic acid and is proven to be compostable [1] , [2] , [3] ). We describe here data for the synthesis and analysis of poly(butylene adipate-co-butylene terephthalate variants with different adipic acid:terephatalic acid ratios and 6 oligomeric PBAT model substrates. Data for the synthesis of the following oligomeric model substrates are described: mono(4-hydroxybutyl) terephthalate ( BTa ), bis(4-(hexanoyloxy)butyl) terephthalate ( HaBTaBHa ), bis(4-(decanoyloxy)butyl) terephthalate ( DaBTaBDa ), bis(4-(tetradecanoyloxy)butyl) terephthalate ( TdaBTaBTda ), bis(4-hydroxyhexyl) terephthalate ( HTaH ) and bis(4-(benzoyloxy)butyl) terephthalate ( BaBTaBBa ). Polymeric PBAT variants were synthesized with adipic acid:terephatalic acid ratios of 100:0, 90:10, 80:20, 70:30, 60:40 and 50:50. These polymeric and oligomeric substances were used as ecoflex model substrates in enzymatic hydrolysis experiments in the article “Substrate specificities of cutinases on aliphatic-aromatic polyesters and on their model substrates” [4] .
