Dynamic mechanical properties of semi-interpenetrating networks based on poly(styrene-co-maleic anhydride): 3. Poly(2,6-dimethyl-1,4-phenylene ether)-cross-poly(styrene-co-maleic anhydride)

Colloid and Polymer Science, 1994
Semi-IPN's based on linear poly(2,6-dimethyl-1,4-phenylene ether) (PPE) and diamine crosslinked poly(styrene-co-maleic anhydride) (PScoMA) copolymers containing small amounts of maleic anhydride (PSA=4.7wt.-% MA, PSB=5.8 wt-% MA) are studied with respect to the influence of cross-linking on the phase behavior.

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.

Tight ultrafiltration: Layer deposition of Trimesoyl chloride/β-Cyclodextrin onto Polysulfone/Poly (styrene-co-maleic anhydride) membrane for water treatment

, 2020
Polysulfone–Styrene Maleic Anhydride (PSF/SMA) ultrafiltration (UF) membranes were prepared by the thermally induced phase separation (TIPS) method. The morphology of the UF membranes was fine tuned by varying the concentration of SMA. The surface of the

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 ...

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 ...

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.
