Preparation of monodisperse PMMA microspheres in nonpolar solvents by dispersion polymerization with a macromonomeric stabilizer
Recently, monodisperse polymer colloids have found a new application as templates for photonic crystals [1]. At a sufficiently high volume fraction and low polydispersity, spherical particles will self assemble into a facecentered cubic lattice, even in the absence of attractive interparticle forces [2]. Such structures can diffract light if the wavelength is comparable to the spacing between t...
متن کاملAn Approach to the Design of a Particulate System for Oral Protein Delivery .II. Preparation and Stability Study of rhGH-Loaded Microspheres in Simulated Gastrointestinal Fluids
The delivery of therapeutic proteins has gained momentum with development of biotechnology. However, large molecular weight, hydrophilic nature and susceptibility to harsh environment of gastrointestinal tract (GIT) resulted in low absorption. The main objective of this work was the design of a particulate system for oral delivery of recombinant human growth hormone (rhGH) on the basis of parti...

متن کاملPreparation and characterization of polystyrene microspheres in the presence of beta-cyclodextrin.
Using styrene as raw material, potassium persulfate as an initiator, beta-cyclodextrin as a stabilizer, polystyrene microspheres were successfully prepared with nice monodisperse feature by means of soap-free emulsion polymerization method. Experimental studies were performed in detail to check the effect of the synthesis process of the microspheres, the stabilizer dosage, monomer concentration...
متن کاملSynthesis of highly monodisperse polystyrene microspheres via dispersion polymerization using an amphoteric initiator.
The highly monodisperse polystyrene (PS) microspheres were produced by dispersion polymerization using an amphoteric initiator, 2,2'-azobis [N-(2-carboxyethyl)-2-2-methylpropionamidine] (VA-057). The polymerization characteristics were investigated and compared with conventional initiators, 2,2-azobis(isobutyronitrile) (AIBN) and benzoyl peroxide (BPO). The monodisperse PS microspheres having t...
