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.

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 ...

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.

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.

Vitronectin adsorption on polystyrene and oxidized polystyrene

Journal of Colloid and Interface Science, 1989
Abstract The secondary structure of human plasma vitronectin (VN) contains considerable β and random structure as ascertained by infrared spectroscopy and circular dichroism. VN adsorption kinetics on polystyrene and oxidized polystyrene were monitored by Fourier transform infrared spectroscopy.

Diffusion of linear polystyrene into crosslinked polystyrene

Polymer, 1997
Abstract The diffusion of linear polystyrene (PS) into its crosslinked counterpart was studied using both neutron reflectivity (NR) and forward recoil scattering (FRES). The penetrant molecular weights were monodisperse and ranged from 10 000 to 690 000 g mol −1 . The molecular weight between crosslinks was kept at 22 000 g mol −1 .

An overview on biodegradation of polystyrene and modified polystyrene: the microbial approach

Critical Reviews in Biotechnology, 2017
Polystyrene is a widely used plastic in many aspects of human life and in industries due to its useful characteristics of low cost, light weight, ease of manufacture, versatility, thermal efficiency, durability, and moisture resistance. However, polystyrene is very stable and extremely hard to degrade in the environment after disposal.

Miscibility, crystallization and morphologies of syndiotactic polystyrene blends with isotactic polystyrene and with atactic polystyrene

Polymer, 2006
Abstract Two-component blends of differing polystyrene (PS), one syndiotactic (sPS) and the other isotactic (iPS) or atactic (aPS), were discussed. The phase behavior, crystallization and microstructure of binary polystyrene blends of sPS/iPS and sPS/aPS with a specific composition of 5/5 weight ratio were investigated using optical microscopy (OM ...
