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 ...

Model polystyrene networks

Faraday Discussions of the Chemical Society, 1974
Abstract Model polystyrene networks have been prepared, at different concentrations in an inert solvent, in such a way that the number of crosslinks is accurately known, and the topology of the network can be varied in a controlled way. The contribution of various network defects to the modulus of the network has been examined.

‘Weak links’ in polystyrene

Polymer Degradation and Stability, 1981
Abstract A first step in the thermal degradation of polystyrene prepared by radical polymerisation has been isolated by heating the polymer in the temperature range 199–280°C. In this step a chain scission process occurs without formation of volatile products, involving, on average, about one bond between structural units in every 10 000.

Thermal degradation of polystyrene

Vacuum, 1953
THE degradation of polymers may be elucidated by various approaches; one of the more accessible routes is a study of the volatile degradation products.

Stress-Birefringence in Polystyrene

Nature, 1950
THE photo-elastic properties of polystyrene at temperatures above its softening point have been investigated earlier1,2, and it has been found that under these conditions the stress-birefringence is in the opposite direction from that found for most other materials.
