Styrene‐Maleimide/Maleic Anhydride Alternating Copolymers
Alternating sequencing of styrene-maleimide/maleic anhydride (S-MI/MA) in the copolymer chain is known for a long time. But since early 2000, this class of copolymers has been extensively studied using various living/controlled polymerization techniques to design S-MI/MA alternating copolymers with tunable molecular weight, narrow dispersity (), and precise chain-end functionality.
Graft Copolymers of Maleic Anhydride and Its Isostructural
Maleic anhydride (MA) and its isostructural analogues (maleic, fumaric, citraconic and itaconic acids and their amide, imide, ester and nitril derivatives) as polyfunctional monomers are being widely used in the synthesis of reactive macromolecules with linear, hyperbranched and self-assembled structures to prepare high performance
Modification of polystyrene maleic anhydride for efficient
After evaporation of the solvent, the modified copolymer was obtained. It was then dried and stored in a vacuum desiccator. Synthesis of DDM-modified copolymer (SMA-2) SMA-2 was prepared as per a reported procedure . Styrene maleic anhydride (SMA) and 4,4-diaminodiphenylmethane (DDM) were dissolved in 5 mL dimethyl acetamide.
Maleic anhydride grafting of polypropylene: peroxide and
The grafting of polyolefins with maleic anhydride (MA) has been incorporated into industrial practice to generate copolymers that can act as coupling agents between the non-polar polyolefins and different polar fillers and reinforcements.
A review on the synthesis of maleic anhydride based
The objective of this review is to provide a comprehensive, informative, valuable and critical summary about the current development in the field of maleic anhydride-based polyurethanes. Generally polyurethane synthesized from Renewable as well as petrochemical sources but Polyurethane from Renewable resources is most explored transformation in
- Is maleic anhydride a plasticizer?
- The purpose of this study was to evaluate the effect of maleic anhydride (MA) as a compatibilizer and a plasticizer. The blends were prepared in a torque rheometer through different mixture processes. Blends prepared with grafted MA showed interfacial adhesion and small domains of PLA in the TPS matrix, due to the use of MA as a compatibilizer.
- What is a maleic anhydride copolymer?
- Maleic anhydride (MAN) copolymers with methyl methacrylate, ethyl methacrylate, methyl acrylate, ethyl acrylate, and butyl acrylate monomers at 1:3 mole ratios were synthesized by free radical polymerization in the presence of azobis(isobutyronitrile) as initiator and dry ethyl acetate as solvent.
- How are maleic anhydride - styrene copolymers synthesized in acetone-Tol?
- Maleic anhydride - styrene copolymers were synthesized in acetone-toluene solution at 60° C by azo-bisisobutironitrile. The copolymers were characterized by Gel Permeation Chromatography and Differential Scanning Calorimetry.
- What is the monoesterification of maleic anhydride-styrene copolymers?
- The monoesterification of the maleic anhydride-styrene copolymers was carried out with methyl, n-propyl, n-butyl, n-hexyl, n-octyl and n-decyl alcohol in tetrahydrofuran solution at 65°C catalyzed by 4-dimethylaminopyridine.
- Does maleic anhydride improve interfacial interaction between Thermoplastic starch/poly (lactic acid) blends?
- The proprieties of thermoplastic starch/poly (lactic acid) (TPS/PLA) blends have been studied by researchers, as well as the incorporation of compatibilizers to improve the interfacial interaction between the blend components. The purpose of this study was to evaluate the effect of maleic anhydride (MA) as a compatibilizer and a plasticizer.
- Does chemical modification of Man copolymers increase rigidity and TG?
- It was shown that the chemical modification of MAN copolymers with 2-amino ethyl benzoate substituents as side chains decreased the free volume of the polymers, and therefore, the rigidity and Tg is increased.
