Morphology control of silicone/poly(methyl methacrylate) (elastic/glassy) composite particles

Abstract

Composite particles consisting of elastic silicone and glassy poly(methyl methacrylate) (PMMA) were prepared. Seeded polymerization of methyl methacrylate (MMA) was carried out in the presence of silicone elastic particles, which...

Morphology of polypropylene/polystyrene composite particles prepared by seeded emulsion polymerization: influence of azo initiator intrinsic charge

“…Composite particles composed of multiple components have attracted a great deal of attention because they can be used in many products such as coatings, 1,2 resin modifiers, 3 catalysts, 4 and adhesives. 5 Preparations of composite particles consisting of various kinds of polymers, [6][7][8] ceramics, 9,10 and metals 11,12 have been reported, and the functions or structures of polymer composite particles are particularly easy to tune to a particular purpose. Since polymer composite particles have unique properties that cannot be achieved by simply mixing particles of individual polymers, 13,14 great attention has been paid to the various phenomena that occur during the process of composite particle formation.…”

Preparation of Polypropylene-Composite Particles by Dispersion Polymerization

“…Composite particles comprising two or more components are variously applied as coatings, , biomedicines, − resin modifiers, and other materials. Thus far, composite particles made of various polymers such as an acrylic polymer, − polyurethane, , epoxy, , fluoropolymer, , and silicone , have been reported. Such composite particles are commonly prepared by polymerizing a second monomer in the presence of polymer seed particles. − …”
