Poly(styrene- co -maleic anhydride) nanoparticles as protein carriers

Materials Letters, 2018
Abstract 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.

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.

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.

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 ...

Dielectric relaxation of monoesters based poly(styrene-co-maleic anhydride) copolymer

Journal of Polymer Research, 2007
A series of alkyl-grafted copolymers based on styrene-maleic anhydride (SMA) copolymers were synthesized by esterification of SMA with several long chain normal aliphatic alcohols. The prepared copolymers were characterized by FT-IR and 1H NMR and DSC.

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.

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

Electrospun polystyrene–poly(styrene-co-maleic anhydride) nanofiber as a new aptasensor platform

Biosensors and Bioelectronics, 2012
Here, 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.

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 ...
