Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

open access: yesMacromolecular Reaction Engineering, EarlyView.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.

Roughness Measurements at Small and Uneven Surfaces of Ceramic Foam Filters

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT This study investigated the possibility of roughness characterization of ceramic foam filters using a laser scanning microscope, examining the influence of magnification, measured area, cutoff wavelength (λc), measured roughness parameter, and position within the ceramic foam on the measured roughness data. Firstly, the effect of magnification
