Influence of the beta crystalline phase fraction on the mechanical behavior of polypropylene/calcium carbonate/ polypropylene–graft–maleic anhydride composites
(São Carlos, 2014)
The formation of the crystalline phase of polypropylene in the presence of four different types of CaCO3 was studied. All composites were prepared by melt mixing and extrusion and the concentration of CaCO3 was maintained ...
Carbon nanotube plasma functionalization: The role of carbon nanotube/maleic anhydride solid premix
(2019-10-15)
Carbon nanotubes (CNT) were functionalized by radio-frequency plasma using maleic anhydride (MA) as a source of functional groups. The MA insertion was performed in the solid form through a mixture with CNT conducted under ...
Design of thermosetting polymeric systems based on benzoxazines modified with maleic anhydride
(John Wiley & Sons Inc, 2018-05)
A novel benzoxazine (BzPFA) with carboxylic acid groups in its structure was synthesized in a two-step process. First, BzPOH monomer was obtained from bisphenol A, paraformaldehyde, and ethanolamine with an initial molar ...
Otimização e validação de metodologia cromatográfica para determinação simultânea de composição monomérica em polímero biodegradável
(Editora Unesp, 2006-01-01)
O biopolímero poli(3-hidroxibutirato) PHB, importante pelas suas propriedades de biodegradabilidade e biocompatibilidade, pode apresentar melhores características termoplásticas quando estruturalmente modificado com anidrido ...
Thermal properties of nylon6/ABS polymer blends: Compatibilizer effect
(2004-02-15)
Nylon6/ABS binary blends are incompatible and need to be compatibilized to achieve better performance under impact tests. Poly(methyl methacrylate/maleic anhydride) (MMA-MA) is used in this work to compatibilize in situ ...
