Temperature and pH-responsive properties of poly(styrene-co-maleic anhydride)-grafting poly(oxypropylene)-amines

Amphiphilic graft copolymer based on poly(styrene-co-maleic anhydride) with low molecular weight polyethylenimine for efficient gene delivery

“…Synthesis and characterization of SMA-PEI 800 (SP) copolymer SP was synthesized by reacting the primary amine in PEI with the anhydride groups in the SMA backbone according to a method previously described, 31 with minor modification. Briefly, PEI 800 (792 mg, 0.99 mmol) dissolved in 20 mL of dimethyl sulfoxide was put into a round-bottomed flask equipped with a mechanical stirrer, followed by dropwise addition of SMA (100 mg, 0.495 mmol of maleic anhydride) in 20 mL of dimethyl sulfoxide.…”

Hierarchical synthesis of silver nanoparticles and wires by copolymer templates and visible light

“…The preparation of POE-amine graft SMA2000 copolymers (SMA-POE) was reported previously in our laboratory [42][43][44]. Typical procedures for preparing POE-amine grafted SMA2000 at 1:1 MA/NH 2 molar ratio are described below.…”

“…The synthesis [42], amphiphilicity [43] and pH-thermoresponse [44] of grafting poly(oxyethylene) [POE] segmented monoamine onto SMA have been extensively studied in our laboratory. The copolymer possesses multiple amidoacid polar functionalities for association with Ag + .…”

Formation of hybrid poly(styrene-co-maleic anhydride)–silica microcapsules

“…Poly(styrene-co-maleic anhydride) is a versatile polymer that can react with different other polymers, which results in tunable properties of the polymer material formed. [14][15][16] Silica particles are known to be suitable for Pickering stabilization. 11,17,18 This is largely caused by their tunable hydrophobicity upon modication.…”
