Closed-Loop Polymer Upcycling by Installing Property-Enhancing Comonomer Sequences and Recyclability
AIMS AND OBJECTIVE The purpose of the present study was to evaluate and compare flexural strength and Staphylococcus aureus adhesion of heat-activated poly (methyl methacrylate [MMA]) resin modified with a comonomer of methacrylic acid (MAA) and MMA monomer. MATERIALS AND METHODS Comonomer preparation was done with the addition of varying concentration of MAA (0, 15, 20, and 25 wt %) to the M...
In this work the colloid stability mechanisms of two sulfonated latexes prepared by different methods are studied. One of the latexes (JM1) was prepared by surfactant-free emulsion copolymerization of styrene (St) and sodiun styrene sulfonate (NaSS), while the second latex (SN9) was prepared by a twostage “shot-growth” emulsion polymerization process using NaSS as ionic comonomer, which is incl...
Ž . The electrocopolymerization of carbazole and acrylamide on highly oriented pyrolytic graphite HOPG from ACN solutions Ž . via cyclovoltammetry CV was studied in order to evaluate the possibility to deposit uniform and thin but pinhole-free and still reactive coatings onto graphite-like substrates. The morphology of the coatings was investigated using atomic force microscopy and the coating ...
