A Polystyrene−Oligothiophene−Polystyrene Triblock Copolymer

Journal of the American Chemical Society, 1998
A well-defined triblock copolymer is synthesized by using a strategy in which the a-coupling of 11 thiophene rings of the middle block and the monodispersity (d.p. = 30 and 1.1) of the two polystyrene outer blocks is ensured. Monofunctional polystyrene is modified with an a-terthiophene unit and two of these units are coupled in a double Stetter ...

Thermal degradation of alkyne-containing polystyrenes

open access: yesJournal of Analytical and Applied Pyrolysis, 2003
The synthesis and thermal behavior of several alkyne-containing polystyrenes was studied. The introduction of the alkynyl group was performed by coupling reaction of poly(p-bromostyrene) with alkynes using palladium/copper catalyst.

Synthesis and evaluation of polystyrene–polybutadiene–polystyrene–dodecafluoroheptyl methacrylate/polystyrene–polybutadiene–polystyrene hybrid antifouling coating

Journal of Colloid and Interface Science, 2014
Copolymers SBS-DFHMA and mesoporous silica SBA-15 were respectively synthesized and SBS-DFHMA were mixed with SBA-15 to prepared hybrid antifouling coatings by a spin-coater. By measuring the surface water contact angle and the attachment of Pseudomonas fluorescens, Chlorella and Diatoms, the antifouling properties of coatings were evaluated.

Immiscibility in polystyrene/sulfonated polystyrene blends

Polymer, 1995
Abstract Miscibility in the binary system of deuterated polystyrene and lightly sulfonated polystyrene has been investigated. Small-angle neutron scattering was used to evaluate the physical state of deuterated polystyrene/polystyrene—1.67% sulfonic acid blends over a wide composition range.

Dielectric properties of polystyrene and polystyrene-chloranil

Thin Solid Films, 1980
Abstract Dielectric permittivities and losses were measured above room temperature in the frequency range 102–105 Hz for undoped and chloranil- (Chl-) doped polystyrene (PS) films (thickness about 15 μm) with progressively increasing Chl concentrations.

Photodegradation of polystyrene and polystyrene containing benzophenone

Polymer Photochemistry, 1983
Abstract The photodegradation of polystyrene has been studied by electron spin resonance, infra-red absorption, viscosity and gel fraction measurements. Irradiations with light from a medium pressure mercury lamp to polystyrene film at 45°C in vacuum, gave rise to the polystyryl radical.
