Styrene 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...
متن کاملPreparation and Characterization of Extruded Composites Based on Polypropylene and Chitosan Compatibilized with Polypropylene-Graft-Maleic Anhydride
The preparation of composites of synthetic and natural polymers represent an interesting option to combine properties; in this manner, polypropylene and chitosan extruded films using a different proportion of components and polypropylene-graft-maleic anhydride (PPgMA) as compatibilizer were prepared. The effect of the content of the biopolymer in the polypropylene (PP) matrix, the addition of c...
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 کاملinfluence of maleic-anhydride-polypropylene (mapp) on wettability of polypropylene/wood flour/glass fiber hybrid composites
the influence of maleic anhydride-polypropylene (mapp) (0, 2, 3 and 5%) as a compatibilizer on the wettability of polypropylene/wood flour/glass fiber hybrid composites was studied by using the contact angle determination technique. sample slats with a cross section of 10×70 mm were made by a twin screw extruder. specimens were conditioned at room temperature and the angles between the water dr...
