Microgel characterization

In this section, a description of the experimental procedure used to prepare and characterize metal nanoclusters stabilized by DMAA-based microgels (M5, MIO, M20) is provided. Details of the experimental procedure used to prepare nanoparticles stabilized by MMA-based microgels have been reported elsewhere [13b]. [Pg.344]

Because the term microgel has the longest tradition and is most commonly used in polymer science and technology it is reasonable to accept it as the generic term for intramolecularly crosslinked macromolecules in solution, a state in which these species of macromolecules are usually handled and characterized. [Pg.142]

Microgels are distinguished from linear and branched macromolecules by their fixed shape which limits the number of conformations of their network chains like in crosslinked polymers of macroscopic dimensions. The feature of microgels common with linear and branched macromolecules is their ability to form colloidal solutions. This property opens up a number of methods to analyze microgels such as viscometry and determination of molar mass which are not applicable to the characterization of other crosslinked polymers. [Pg.223]

For some particular formulations (e.g., unsaturated polyesters formulated with a high styrene concentration), the primary chains that are first generated are not miscible with the unreacted monomers. In this case, there is a phase separation phenomenon characterized by the appearance of relatively large polymer-rich particles. These microgels are formed by a thermodynamic driving force and their sizes are large enough to be detected in both the course of polymerization and the final materials. [Pg.82]

Inhomogeneous open networks characterized by spatial fluctuations of the crosslink density (nodular/globular morphologies, microgels, see Chapter 7). [Pg.311]
