Hydrolysis of 4-acetoxystyrene polymers prepared by atom transfer radical polymerization

open access: yesJournal of Polymer Science Part A, 1999
Hydrolysis of 4-acetoxystyrene polymers prepared by atom transfer radical polymerization was carried out under various reaction conditions. It was found that hydrazinolysis of 4-acetoxystyrene homopolymers, random and block copolymers with styrene in 1,4-

Synthesis and characterization of low-molecular-weight azo-acetoxystyrene and azo-naphthalene oligomers via stable free radical polymerization (SFRP)

open access: yesCanadian Journal of Chemistry, 2010
As an approach toward controlled molecular architecture through stable free radical polymerization (SFRP), we have prepared a series of oligomers of controlled molecular weights (Mn) and low polydispersities (structures 2 and 3, with n values ranging ...

Living atom transfer radical polymerization of 4-acetoxystyrene

open access: yesMacromolecular Rapid Communications, 1997
Living atom transfer radical polymerization (ATRP) of 4-acetoxystyrene (1), a protected 4-vinylphenol, leading to poly(4-acetoxystyrene) with well-defined molecular weight and narrow molecular weight distribution was carried out in bulk with a,a ...

Poly(p-acetoxystyrene) resin: a prospective new support for combinatorial synthesis

Journal of the Chemical Society, Perkin Transactions 2, 1995
A range of spherical particulate resins have been prepared in high yield by suspension polymerisation of mixtures of p-acetoxystyrene (AS), styrene (S) and divinylbenzene. The particle size is typically 100–400 µm. The functional group content has been varied from ca. 15–60% and the degree of cross-linking from ca. 2–20%.

Preparation and characterization of polystyrene–poly(p-acetoxystyrene) and polystyrene–poly(p-vinylphenol) composite latex particles

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2002
Abstract Polystyrene-core poly(p-vinylphenol)-shell (PS–PVPh) latexes were prepared by the hydrolysis of polystyrene-core poly(p-acetoxystyrene)-shell (PS–PAS) latexes. Polymerization conditions required for uniform core/shell structures were identified.
