“…The possibility of polymerization of FA is feasible since in their structure many double bonds are found and available . Therefore, there is favored radical polymerization reaction through the hydrogen in the allyl position, duo to the higher reactivity of this hydrogen creating a distinct monomer [4]. A large number of polymers applications results from their early properties and the way they are processed.…”

“…A large number of polymers applications results from their early properties and the way they are processed. In order to increase these applications and also to improve some properties, it is common in polymer industry to under go by synthesis modification [4]. In a recent studies fatty acids demonstrated biological activity [5][6][7][8][9][10][11][12][13][14][15][16][17][18] and some physical properties [19][20][21][22][23][24][25][26][27][28] and its polymers [29][30][31][32][33][34][35][36][37][38][39][40][41].…”

In this study, new semicarbazide derivatives [E1-E5] were prepared by the reaction of semicarbazide with different fatty acids (olic, linolic, linolinic, recenolic and cinnamic acid) in DMF, then this compounds will polymerization with malic anhydride in H2O2 as initiator to get [EP1-EP5]. The prepared compounds were characterized by physical properties, UV-Vis, FT-IR, 1 H-NMR, 13 C-NMR and TGA analysis.TLC checked the purity for these compounds.The antibacterial activity were studied against different kinds of bacteria, namlyStophylococcuceaures,Stophylococcuce Saprophytic and Protes.

O crescimento do consumo humano tem causado inúmeros transtornos para o meio ambiente, inclusive pelo descarte inapropriado de materiais inorgânicos de longa vida útil. A incorporação de potenciais resíduos na fabricação de painéis aglomerados à base de madeira se apresenta como uma alternativa a essa problemática. Esta pesquisa teve por objetivo avaliar os efeitos da substituição parcial de partículas de madeira por partículas de poliestireno expandido aglutinados com poliuretano de mamona. As partículas de madeira (50% de Pinus + 50% de Eucalipto) foram substituídas por 25 e por 50% (em massa) de partículas de poliestireno expandido visando aprimorar as propriedades físicas e mecânicas de painéis fabricados com 5% de adesivo poliuretano à base de óleo de mamona. Os compósitos fabricados com 50% de partículas de poliestireno resultaram nos melhores valores das propriedades físicas e mecânicas avaliadas (ABNT NBR 14810 e EN 312), designando credibilidade à produção de painéis com a substituição parcial de partículas de madeira por partículas de poliestireno.
