Fluorescent polymer made from chemical modification of poly(styrene-co-maleic anhydride)

Reactive and Functional Polymers, 2002
Abstract Poly(styrene-co-maleic anhydride) (SMA) was modified by commercially available fluorescent dye, 4-amino-N-(2,4-dimethylphenyl)-1,8-naphthalimide, to prepare fluorescent poly(styrene-co-maleimide) (SMI). FT-IR, UV–Vis and fluorescent spectra of this polymer were investigated.

Amidification of poly(styrene-co-maleic anhydride) with amines in tetrahydrofuran solution: A kinetic study

Polymer Bulletin, 1992
The kinetics of the reaction between a styrene-maleic anhydride copolymer (SMA) and amines was investigated in tetrahydrofuran solution between 0°C and 40°C. This reaction converts the maleic anhydride (MA) into the corresponding amide-acid, while the consecutive reaction of the generated acid with amine forming a diamide or transformation of the acid ...

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%.

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 ...

Interpolymer complexation in hydrolysed poly(styrene-co-maleic anhydride)/poly(styrene-co-4-vinylpyridine)

European Polymer Journal, 2008
Abstract Complexation between hydrolysed poly(styrene- co -maleic anhydride) (HSMA) copolymers containing 28% and 50% maleic anhydride and a poly(styrene- co -4-vinylpyridine), St4VP32 copolymer with 32% of 4-vinylpyridine content has been investigated.

Effect of maleic anhydride content on the rheology and phase behavior of poly(styrene-co -maleic anhydride)/ poly(methyl methacrylate) blends

Rheologica Acta, 2002
We investigated the thermo- rheological behavior of high glass transition, high molecular weight and small dynamic asymmetry blends of poly(styrene-co-maleic anhydride) (SMA) and poly (methyl methacrylate) (PMMA) with varying amounts of maleic anhydride (MA) content, namely 8 wt%, 14 wt% and 32 wt%, in the SMA component.

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 ...

Multivalent mannose-displaying nanoparticles constructed from poly{styrene-co-[(maleic anhydride)-alt-styrene]}

Organic & Biomolecular Chemistry, 2009
Micellar mannose nanoparticles were constructed from poly{styrene-co-[(maleic anhydride)-alt-styrene]} with fluorophores or quenchers doped into the hydrophobic inner cores, allowing the direct monitoring of multivalent lectin-glycan interactions. The mannose-displaying nanoparticles bind Con A and sperm surface lectins with high affinity, suggesting ...

Structure and properties of blends of poly(ethylene-co-vinyl alcohol) with poly(styrene-co-maleic anhydride)

Journal of Applied Polymer Science, 1997
In the present study, ethylene/vinyl alcohol (EVAL) copolymers with different hydroxyl contents were melt mixed with styrene/maleic anhydride (SMA) copolymers. These two copolymers have functional groups capable of reacting intermolecularly, giving stable products.

Highly conductive, crosslinked ionomers based on poly(styrene-co-maleic anhydride) for water electrolysis

Journal of Materials Chemistry A, 2013
Hydrogen production through water electrolysis calls for a low-cost non-fluoro membrane to make the process economically viable due to the high cost and environmental concerns of the current fluorinated ionomers. Here, we present such an ionomer with high proton conductivity based on the hybrid of commercially available poly(styrene-co-maleic anhydride)
