Preparation and Characterization of Poly (Styrene-Co-Maleic Anhydride)-Modified Boron Particles
Journal of Dispersion Science and Technology, 2010The surface modification of boron powder with poly (styrene-co-maleic anhydride) (SMA) has been achieved through the reactions between the hydroxy groups on the surface of boron and the maleic anhydride groups in SMA. This novel polymerically modified boron was characterized using IR, TGA, TEM, and laser grain size analyzer.

Vibration welding of glass-filled poly(styrene-co-maleic anhydride)
Journal of Adhesion Science and Technology, 2001Vibration welding is used to assess the weldability of 16 wt% glass-filled poly(styrene-comaleic anhydride) (16-GF-SMA). Data are presented on the strengths of butt welds for two specimen thicknesses and T-welds for one specimen thickness. The maximum weld strength of butt joints is shown to be only 35% of the tensile strength of the material. T-joints

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 ...

Poly(styrene- co -maleic anhydride) nanoparticles as protein carriers
Materials Letters, 2018Abstract Considering the increasing interest for protein immobilization on nanoparticles, in this work, we demonstrate the preparation of poly(styrene-co-maleic anhydride) (PSMA) nanoparticles and their capability to conjugate the proteolytic enzyme papain.

Properties of miscible blends of polyglutarimide with poly(styrene-co-maleic anhydride)
Polymer, 1997In 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

Miscibility and esterification in the poly(styrene-co-maleic anhydride)/phenoxy blends
Journal of Applied Polymer Science, 1998The 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, 1999Using 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, 1999Abstract 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, 1996AbstractPrimary 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.

Electrospun polystyrene–poly(styrene-co-maleic anhydride) nanofiber as a new aptasensor platform
Biosensors and Bioelectronics, 2012Here, we report the use of an aptamer-immobilized electrospun polystyrene-poly(styrene-co-maleic anhydride) (PS-PSMA) nanofiber as a new aptasensor platform for protein detection. Two thrombin-binding aptamers (TBA29 and TBA15) were used as a model platform to facilitate efficient detection of thrombin in a sandwich manner.
