Synthesis and Crystallization of Anisotropic Polymer Colloids
Using seeded emulsion polymerization, methods are presented to synthesize polymer colloids with chemical and shape anisotropy. Two types of particles consisting of interpenetrating spheres, or dicolloids, are synthesized with length scales varying from approximately 300 nm to roughly 1.2 microm. …

The effects of particle shape, size, and interaction on colloidal glasses and gels
Using multiple step seeded emulsion polymerization reactions, colloid particles of tunable shape are synthesized from polystyrene. In all, four particle shapes are studied referred to as spheres (S), heteronuclear dicolloids (hDC), symmetric homonuclear dicolloids (sDC), and tricolloids (TC). Two …

Multiscale simulation of heterophase polymerization : application to the synthesis of multicomponent colloidal polymer particles
Heterophase polymerization is a technique widely used for the synthesis of high performance polymeric materials with applications including paints, inks, adhesives, synthetic rubber, biomedical applications and many others. Due to the heterogeneous nature of the process, many different relevant …

Investigations of biphasic seeded emulsion polymerizations in a continuous tubular reactor
… development of a continuous tubular process for emulsion polymerization. Prior approaches have mostly focused on transposing batch emulsion polymerization recipes into tubular reactors. While this transposition had been successful in producing low solids contents material, it failed at producing …

Synthesis and rheology of pH-responsive particles with shape anisotropy
Seeded emulsion polymerization is used to produce large quantities of shape anisotropic, amphoteric particles in a size range of about 1 µm. Two different kinds of shape anisotropic particles are prepared for comparison to study the effects of incorporating pH-responsive groups on the properties of …

Fracture-induced mechanophore activation and solvent healing in poly(methyl methacrylate)
… nanoparticles is synthesized via a free radical polymerization. Specimens of this material are fabricated for Single Edge Notch Tension (SENT) testing. The rubber toughened SP-PMMA specimens are first prestretched to approximately 35% axial strain to align the spiropyran molecules in the …
