(Meth)acrylic Cross-Linked Polymer Microparticles: Synthesis by Dispersion Polymerization and Particle Characterization

Rheological Properties of (Meth)acrylic Cross-Linked Polymer Microparticles, 2. Role of Interactions in Non-Reactive and in Reactive Diluents. Copolymerization Studies

“…All CPM solutions in xylene and styrene were shear thinning and they were well fitted by the Cross' equation defined in Equation (5) on the whole range of measured shear rates. This result was consistent with our previous study on epoxy functionalized CPM viscosity in xylene [8] which showed shear thinning behavior for CPM concentration higher than 30 wt.-%. Moreover, the molar mass of CPM used in this work was much higher than the critical molar mass below which CPM seemed to loose its specificity.…”

“…Moreover, the molar mass of CPM used in this work was much higher than the critical molar mass below which CPM seemed to loose its specificity. This limiting low molar mass was found to be equal to about 15 000 g/mol for CPM of composition octadecyl acrylate/IBOA/GMA/HDDA = 30/52/13/5 mol-%, [8] while in this study all CPM had mass-average molar mass higher than 10 5 g/mol.…”

Use of Acrylic Functionalized (Meth)acrylic Cross‐Linked Polymer Microparticles in Photopolymerized Acrylic Films

“…The size of the particles was in the range of 20 to 25 nm and was rather monodisperse. It well agreed with previous electronic micrographs which have been obtained with dry unreacted CPM 32. The film pattern was however rather diffuse.…”

Investigation Into Accessible Surface Vinyl Concentrations of Nonstoichiometric PDMS Microspheres from Hydrosilylation Reactions and Their Further Crosslinking Reactions

“…This can be explained by the silicone oil promoting the diffusion rate of the crosslinker and diluting the polymer chains in the macroscopic PDMS network simultaneously. When the weight fraction of the silicone oil increased by up to 90% (wt), the PDMS microspheres in the mixture were diluted sufficiently to avoid inter‐particle interactions. As a result, no crosslinking reaction between the PDMS microspheres took place and no macroscopic PDMS network could be obtained.…”
