The response of macromolecular binary mixtures to shear flow is rather complex. Experimental evidence suggests that both shear-induced mixing and shear-induced demixing, observed as suppression or enhancement of concentration fluctuations, respectively, can occur (Hobbie et al, 1994; Larson, 1992; Takebe et al, 1989), depending on the amount of ...

In order to improve the oil-repellent and antifouling ability of the antifog coatings, a poly(vinyl alcohol)/hydrolyzed poly (styrene-co-maleic anhydride)/fluorocarbon surfactant (PVA/H-PSMA/FC) was prepared by incorporating a fluorocarbon surfactant ...

Blends of PA 6 with SMA or with 12.5–100% fatty amine (C 18) modified SMA at compositions 95/5–60/40 were studied. Particle size of SMA dispersed in PA 6 matrix was around 0.1 μm due to in situ compatibilizer formation. The strength and stiffness of the blends were higher and toughness unchanged in comparison with PA 6 values.

Mesoporous hypercrosslinked styrene and maleic anhydride microspheres were prepared by suspension polymerization using a free radical initiator. Degree of crosslinking was increased by increasing the divinylbenzene content. Scanning electron micrographs revealed the introduction of definite compactness in the microspheres with increase in ...

Liquid crystallization of poly(styrene‐co‐maleic anhydride) induced by intermolecular hydrogen bonds
Journal of Applied Polymer Science, 1999The liquid crystallization of general polymer (GP) with maleic anhydride in the main chain has been realized through molecular recognition and self-assembly based on intermolecular hydrogen bonds. Poly[styrene-co-(N-4-carboxylphenyl)maleimide] (SMIBA) was synthesized by imidization and dehydration of Poly(styrene-co-maleic anhydride) (SMA) with p ...

Dielectric relaxation of monoesters based poly(styrene-co-maleic anhydride) copolymer
Journal of Polymer Research, 2007A 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.

Synthesis and characterization of CdS nanocrystals in poly(styrene-co-maleic anhydride) copolymer
Colloid and Polymer Science, 2003CdS nanocrystals were synthesized in N, N-dimethylformamide solution of poly(styrene-co-maleic anhydride) random copolymer through the reaction of thiourea with cadmium acetate. The resulting random copolymer/CdS nanocrystal composites obtained under different reaction times or cadmium acetate concentrations were very stable and gave a bright ...

Synthesis of a new photocrosslinkable prepolymer, based on poly(styrene-co-maleic anhydride)
Reactive and Functional Polymers, 1996Abstract Photocrosslinkable prepolymers were synthesized by using poly(styrene- co -maleic anhydride) as the polymeric backbone and 4-[2-(4-[aminomethyl]phenyl)ethenyl]pyridine as the crosslinking agent. The photochemical [2+2] cycloaddition of the ethylene double-bond is utilized as the crosslinking principle.
