Grafting of Tetrahydrophthalic and Maleic Anhydride Onto Polyolefins in Solution
Polietileno de baixa densidade (LLDPE) com comonômeros 1-buteno e 1-octeno foram funcionalizados com anidrido tetrahidroftálico (THA) e anidrido maléico (MA) em solução na presença de peróxido de benzoíla (BPO), de acordo com planejamentos fatoriais. As variáveis testadas foram concentração de anidrido, concentração de peróxido, tempo de reação e tipo de comonômero. As formulações foram analisa...
متن کاملMechanical Properties of Polypropylene Coating Containing Maleic Anhydride on Plain Carbon Steel
Using Electrostatic Spray Coating Technique, Polypropylene Powder (EPD 60R) was applied on carbon steel substrates at room temperature. In order to obtain a uniform coating, steel substrates with powder coatings were heated in a vacuum oven at various temperatures up to 250° C for various periods of time up to 45 min and a pressure of 200 mb. The coatings produced had thicknesses of around 470 ...

متن کاملImproving the mechanical and thermal properties of gelatin hydrogels cross-linked by cellulose nanowhiskers.
This study demonstrates the preparation of a renewable and biocompatible hydrogel with superior mechanical properties consisting of a gelatin matrix cross-linked with oxidized cellulose nanowhiskers. We found an increased degree of chemical cross-linking (0.14-17%) between gelatin and nanowhiskers with the increased amount of aldehyde contents (0.062-0.230mmolg(-1)). (1)H nuclear magnetic reson...
متن کاملStyrene Maleic Anhydride Copolymerization in a Recycle Tubular Reactor: Reactor Stability and Product Quality
Ahstrct-Styrene maleic anhydride copolymers (SMACs) are of particular commercial and academic interest. The bulk copolymer&&ion reaction is characterized by a very fast reaction rate and an important gel effect. The copolymer has a strong tendency to be alternate when maleic anhydride is in excess. In order to obtain a copolymer with less than 50% of incorporated MA, a good quality of mixing mu...
