- Can the Reaction Mechanism of Radical Solution Polymerization Explain the Microgel Final Particle Volume in Precipitation Polymerization of N-Isopropylacrylamide?
Otto L. J. Virtanen, Helmi M. Ala-Mutka and Walter Richtering
Article first published online: 27 MAY 2015 | DOI: 10.1002/macp.201500118
Final particle volume of poly(N-isopropylacrylamide) microgels correlates with the kinetic chain length predicted by the radical solution polymerization mechanism. This correlation is explained by the accumulation rate of particle stabilizing ionic initiator fragments to the particles during the early reaction, which depends on the kinetic chain length. Properties of radical polymerization are used to tune the final particle volume as desired.
- Preparation of pH-Responsive Amphoteric Glycogen Hydrogels by α-Glucan Phosphorylase-Catalyzed Successive Enzymatic Reactions

Amphoteric glycogen hydrogels are prepared by thermostable α-glucan phosphorylase-catalyzed successive α-glucuronylation, α-glucosaminylation, and polymerization of glycogen using different substrates, which show the pH-responsive behavior.
- Multidetector-ThF3 as a Novel Tool for the Investigation of Solution Properties of Amphiphilic Block Copolymers
Nyashadzashe Ngaza, Margaretha Brand and Harald Pasch
Article first published online: 19 MAY 2015 | DOI: 10.1002/macp.201500070
In this study, multidetector thermal FFF is utilized to study amphiphilic block copolymers in different selective and nonselective solvents. Amphiphilic block copolymers have the ability to form micelles or aggregates dependent on solvent and conditions. The effect of different polymer-solvent systems on the diffusion and thermal diffusion coefficients, and the resultant separation, is studied.
- Organocatalytic Polymerization of Furfuryl Methacrylate and Post-Diels–Alder Click Reaction to Cross-Linked Materials
Shuo (Kelvin) Feng, Meghan Schmitt and Eugene Y.-X. Chen
Article first published online: 19 MAY 2015 | DOI: 10.1002/macp.201500079
Furfuryl methacrylate is effectively polymerized by the P4-phosphazene superbase and its cross-linked materials are prepared using the Diels–Alder “click” reaction with C60 and a bismaleimide.
