Abstract null null Enzymatically synthesised poly(glycerol adipate) (PGA) has shown a palette of key desirable properties required for a biomaterial to be considered a ‘versatile polymeric tool’ in the field of drug delivery. PGA and its variations can self-assemble into nanoparticles (NPs) and interact at different levels with small active molecules. PGA derivatives are usually obtained by functionalising the glyceryl side hydroxyl group present along the main polymer scaffold. However, if the ...

Abstract The development of polymeric nanomaterials, combining properties of polymers and superparamagnetic nanoparticles, has potential for biomedical applications, such as treatment of tumors through intravascular embolization and hyperthermia. Therefore, this work aims at development of a new magnetopolymeric fluid formed by magnetic nanoparticles of iron oxide (Fe3O4) coated with chemically modified oleic acid and which were uniformly dispersed in spherical nanoparticles of poly(vinyl pivala...

Glycerol is one of the major residues obtained during biodiesel transesterification. Microfibrillated cellulose was obtained from the empty bunches of palm oil, which is a residue of biomass extracted oil. Therefore, the objective of this work is to apply two important residues of oil chemistry industry, glycerol and lignocellulose biomass, in addition to acrylic acid to synthesize a polymer matrix in form of hydrogel for water absorption applications. To produce the polymer matrix, glycerol was...

In this work, we describe the application of a synthetic enzyme (synzyme) as the catalyst to promote the multicomponent synthesis of isoxazol-5(4H)-one derivatives. The catalytic system could be used up to 15 times without any notable loss of its activity. Some derivatives showed fluorescence and their photophysical data were evaluated. The mechanism of the reaction was, for the first time, investigated and, among the three reaction pathway possibilities, only one was operating under the develop...

Molecularly imprinted polymers (MIP) are known as high selective sorbent, however, its application in aqueous medium is very limiting. In this way, a new hybrid MIP was successfully synthesized for saccharin (SAC) extraction in aqueous medium. SAC determination in surface waters becomes a challenge due to high dissipation that results in low concentration and susceptibility to potential interferences. Two polymer materials synthesized through bulk (HMIP-B) and suspension (HMIP-S) polymerizations...

Abstract This present work focuses on the synthesis of styrene / n-acylglycerol (n-ACG) (a macromonomer formed by glycerol esterification with acrylic acid catalyzed by methane sulfonic acid) copolymers through suspension polymerization process. The final properties of poly(styrene-co-n-acylglycerol) was strongly dependent on the n-ACG fraction into the polymer chains. The effect of n-ACG on the copolymer properties was evaluated and a huge reduction in both the thermal stability and the Tg valu...
