Journal ArticleDOI
The effects of specific interactions on the surface structure and composition of miscible blends of poly(vinyl alcohol) and poly(N-vinyl-2-pyrrolidone)
Lin Li,Chi Ming Chan,Lutaoi Weng +2 more
TL;DR: In this paper, a single glass transition temperature (T g ) was observed for all polyvinyl alcohol (PVAL)/poly(N-vinyl-2-pyrrolidone) (PVP) blends, suggesting that PVAL/PVP blends are miscible within the compositions considered.
Journal ArticleDOI
XPS analysis (ESCA) of the surface composition of poly(styrene/2-hydroxyethyl methacrylate) microspheres produced by emulsifier-free emulsion polymerization
TL;DR: In this article, the HEMA content at the surface of styrene and 2-hydroxyethyl methacrylate (HEMA) was determined by both quantitative C1s/O1s analysis and c1s peak shape analysis of the x-ray photoelectron spectroscopic spectra.
Journal ArticleDOI
Surface Chemical Characterization Using XPS and ToF-SIMS of Latex Particles Prepared by the Emulsion Copolymerization of Methacrylic Acid and Styrene
TL;DR: In this article, a series of colloids based on poly(styrene) were prepared by emulsion copolymerization with various proportions of methacrylic acid, and X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) were used to monitor changes in particle surface composition.
