| Popis: | Biopolymers are sustainable materials derived from renewable sources that have relevant and industrially attractive properties such as biodegradability, biocompatibility and antimicrobial effect. Thus, these were the target of several experimental studies, widely published in the literature and used in our daily lives. This paper presents a preliminary investigation on the polyesterification of a malic acid/glycerol mixture in order to obtain the poly(glycerol-co-malic acid) to be evaluated as a bioadhesive. For this, different reaction conditions were evaluated by varying the concentrations of malic acid, glycerol and zinc chloride(II) as catalyst, carried out according to the central composite rotatable design. The polymerizations were monitored by acidity index, hydroxamic acid test and conversion rate and the obtained materials characterized by FTIR. Poly(glycerol-co-malic acid) was obtained in yields of 38 to 68% which show that such method is promising for obtaining this new biopolymer aimed as bioadhesive. |
