Thermal radical polymerization of Bis(methacrylamide)s
Stéfani Becker Rodrigues, Fabrício Mezzomo Collares, Douglas Gamba, Vicente Castelo Branco Leitune, Cesar Liberato Petzhold.
Abstract: Methacrylamides monomers for dental applications were synthesized using a one-step procedure starting from methacrylic anhydride and the respective diamine: N,N’-(propane-1,3-diyl)-bis(N-ethyl-2-methylacrylamide) (1), N,N’-(butane-1,4-diyl)-bis(2-methacrylami

Evaluation of degradation of furanic polyamides synthesized with different solvents
Cláudia Moreira da Fontoura, Vinicios Pistor, Raquel Santos Mauler.
Abstract: Aromatic polyamides have properties of industrial relevance. However, the industrial and technological advancement has followed the trend of sustainability by seeking renewable source materials. In this work, polyamides were synthetized using 2,5-furandicarbo

Tribology of natural Poly-Ether-Ether-Ketone (PEEK) under transmission oil lubrication
Thiago Fontoura de Andrade, Helio Wiebeck, Amilton Sinatora.
Abstract: High performance polymeric materials such as poly-ether-ether-ketone (PEEK) are increasingly being used for challenging tribological applications in order to replace metal parts in vehicle engines and transmissions. The tribology of natural PEEK, under oil-lu

Factorial design to obtain magnetized poly(ethyl acrylate-co-divinylbenzene)
Kelly Lúcia Nazareth Pinho de Aguiar, Kaio Alves Brayner Pereira, Marcelo Sierpe Pedrosa, Márcia Angélica Fernandes e Silva Neves.
Abstract: Magnetized polymers are produced by incorporating magnetic particles in a polymeric matrix. This article describes the use of the suspension polymerization technique using ethyl acrylate and divinylbenzene as monomers, in the presence of heptane and/or toluen

Castor polyurethane used as osteosynthesis plates: microstructural and thermal analysis
Francisco Norberto de Moura Neto, Ana Cristina Vasconcelos Fialho, Walter Leal de Moura, Adriana Gadelha Ferreira Rosa, José Milton Elias de Matos, Fernando da Silva Reis, Milton Thélio de Albuquerque Mendes, Elton Santos Dias Sales.
Abstract: Bone fractures to be corrected need stabilization of their extremities, which is achieved with the use of plates and screws. This research aimed to produce castor bean polyurethane (Ricinus communis), to make resorbable plate, structural and thermal analysis.
