Molecular separation using poly (styrene-co-maleic anhydride) grafted to γ-alumina: Surface versus pore modification

Journal of Membrane Science, 2019
Here, we report the covalent coupling of poly (styrene-co-maleic anhydride) onto γ-alumina to develop high-performance organic solvent nanofiltration (OSN) membranes. A high molecular weight (Mw) alternating copolymer of maleic anhydride (MA) and styrene (St) was synthesized and directly grafted to the γ-alumina membrane, while commercially available ...

Study on polymer blends of poly(styrene-co-acrylonitrile) and poly(styrene-co-maleic anhydride)

Polymer, 1988
Abstract Polymer blends of poly(styrene- co -acrylonitrile) and poly(styrene- co -maleic anhydride) have been investigated by differential scanning calorimetry and light scattering measurements. Depending on the copolymer compositions it is possible to obtain miscible and immiscible blends and blends with lower critical solution temperature behaviour.

Synthesis and characterization of CdS nanocrystals in poly(styrene-co-maleic anhydride) copolymer

Colloid and Polymer Science, 2003
CdS nanocrystals were synthesized in N, N-dimethylformamide solution of poly(styrene-co-maleic anhydride) random copolymer through the reaction of thiourea with cadmium acetate. The resulting random copolymer/CdS nanocrystal composites obtained under different reaction times or cadmium acetate concentrations were very stable and gave a bright ...

Photooxidation of poly(styrene-co-maleic anhydride) using a QUVB-313 light source

Polymer Degradation and Stability, 1991
Samples of 1:1 and 2:1 poly(styrene-co-maleic anhydride) films were exposed to radiation from a QUVB-313 light source under atmospheric oxygen and their photooxidative reactions studied using FTIR, UV-VIS and 13C NMR spectroscopy. A major finding was that the bulk of the photodegradation resulted in loss of low molecular weight volatile fragments from ...

Hybrid networks based on poly(styrene-co-maleic anhydride) and N-phenylaminomethyl POSS

Polymer, 2013
Abstract Novel PSMA-POSS nanocomposites were prepared, in which N-phenylaminomethyl polyhedral oligomeric silsesquioxane (POSS) was conducted as crosslink agent to incorporate to poly(styrene-co-maleic anhydride) (PSMA). POSS was introduced by one-step reactive solution blend in amounts of 1–30 wt%.

Synthesis of a new photocrosslinkable prepolymer, based on poly(styrene-co-maleic anhydride)

Reactive and Functional Polymers, 1996
Abstract Photocrosslinkable prepolymers were synthesized by using poly(styrene- co -maleic anhydride) as the polymeric backbone and 4-[2-(4-[aminomethyl]phenyl)ethenyl]pyridine as the crosslinking agent. The photochemical [2+2] cycloaddition of the ethylene double-bond is utilized as the crosslinking principle.

Reaction effect on the properties of poly(ethylene terephthalate) and poly(styrene- co -maleic anhydride) blends

Polymer, 2000
Poly(ethylene terephthalate) (PET) was blended with polystyrene (PS) and poly(styrene-co-maleic anhydride) (PScMA). The two blend systems were immiscible based on the glass transition temperatures measured by differential scanning calorimetry (DSC). In the case of 70 and 90% PScMA blends, the reaction between ester groups of PET and maleic anhydride ...

Modification of Poly(styrene-co-Maleic Anhydride) with Amino Acids in the Melt

Chemical Engineering & Technology, 2000
In this work we made conversions of poly(styrene-co-maleic anhydride) (S/MA) with the aliphatic amino alcohols 2-amino ethanol, 3-amino propanol and aromatic amino alcohols like 3-amino phenol (3AP), 5-amino naphthol (5AN) and 3-amino benzyl alcohol (3 ABA) in the melt.

Nonlinear rheological response of phase separating polymer blends: Poly(styrene-co-maleic anhydride)/poly(methyl methacrylate)

Journal of Rheology, 2000
We investigate the thermorheological properties of a partially miscible polymer blend exhibiting lower critical solution temperature phase diagram and having high glass transition and molecular weight constituents, namely poly(styrene-co-maleic anhydride)/poly(methyl methacrylate), SMA/PMMA, in the nonlinear regime.

Controlled “Grafting-from” of poly[styrene-co-maleic anhydride] onto polydienes using nitroxide chemistry

European Polymer Journal, 2010
Abstract High-throughput experimentation was used for the functionalization of polybutadiene and polyisoprene with several kinds of nitroxide moieties at 135 °C, as well as for kinetic investigations of the controlled free radical grafting of styrene and maleic anhydride onto the functionalized polydienes at 125 °C.
