Performance intensification of the polysulfone ultrafiltration membrane by blending with copolymer encompassing novel derivative of poly(styrene-co-maleic anhydride) for heavy metal removal from wastewater

Chemical Engineering Journal, 2018
A simple, scalable, novel polymer was synthesized by the aminolysis of poly(styrene-co-maleic anhydride) cumene terminated (PSMAC) using p-aminohippuric acid.

Properties of miscible blends of polyglutarimide with poly(styrene-co-maleic anhydride)

Polymer, 1997
In the present study, blends of styrene/maleic anhydride copolymer with polyglutarimide were studied using a variety of methods. The blends were found to be miscible over the entire composition range and showed positive deviations in glass transition temperature from the ideal (linear) behaviour. Fourier transform infra-red spectra of the blends showed

Preparing and applying a poly(styrene-co-maleic anhydride)-g-polyetheramine hyperdispersant

Pigment & Resin Technology, 2022
Purpose The purpose of this study was the preparation of a poly(styrene-co-maleic anhydride)-g-polyetheramine (SMA-g-PEA) hyperdispersant that reduces the viscosity of the system and improves the colouring intensities of pigments.

Miscibility and esterification in the poly(styrene-co-maleic anhydride)/phenoxy blends

Journal of Applied Polymer Science, 1998
The miscibility and esterification in poly(styrene-co-maleic anhydride) (PSTMA)/phenoxy blends were investigated by DSC and FTIR. The blends prepared by casting exhibited a single composition-dependent but broad T g during the first scanning. The broadness of the T g transition range is due to the presence of microphases in the blends, which acquired

Direct polymer reaction of poly(styrene‐co‐maleic anhydride): Polymeric imidization

Journal of Applied Polymer Science, 1999
Using direct polymer reaction of poly(styrene-co-maleic anhydride) (SMA), a synthesis of copolymer of styrene and N-aryl succinimide (SMI) has been investigated. SMI copolymers were synthesized from SMA copolymers by a concerted two-step reaction, which consisted of the condensation reaction (step 1) of SMA with aromatic amine to prepare a precursor ...

Miscibility and properties of polyglutarimide poly(styrene-co-maleic anhydride) blends

Polymer, 1999
Abstract In the present study, blends of polyglutarimide (PGI) with styrene/maleic anhydride (SMA) copolymers showed complete miscibility with SMA containing 25, 33 and 50 mol.% maleic anhydride (MA), whereas blends with SMA containing 8 mol.% MA were found to be immiscible.

Reactive compatibilization of poly(styrene‐Co‐maleic anhydride)/poly(phenylene oxide) blends

Macromolecular Symposia, 1996
AbstractPrimary amine terminated polystyrene (PS‐NH2), with Mn=12,000 g/mol and Mw=23,000 g/mol, was applied as a reactive compatibilizer for poly(styrene‐co‐maleic anhydride)/poly(phenylene oxide) (SMA/PPO) blends, in which both an impact modifier for the continuous SMA phase, viz. ABS, and the dispersed PPO phase, viz. SEBS, was incorporated.

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.

Poly(styrene-alt-maleic anhydride) derivatives as potent anti-HIV microbicide candidates

Bioorganic and Medicinal Chemistry Letters, 2009
Topical microbicides offer women the opportunity to protect themselves from sexual HIV transmission under their own control. A series of poly[styrene-alt-(maleic anhydride)] derivatives were prepared by amidation or hydrolysis of the anhydride moiety ...
