Submicron polyethylene particles from catalytic emulsion polymerization.
Particles of linear polyethylene (M(n) = (2-3) x 10(3) g x mol(-)(1); M(w)/M(n) = 2-4) obtained by catalytic emulsion polymerization of ethylene possess a nonspherical, lentil-like shape with an average aspect ratio of ca. 10 and diameters from 30 to >300 nm, as determined by TEM and AFM. The particle structure results from a stacking of the lamellae along the one shorter axis of the lentils (i...
متن کاملExperimental data in support of continuous microwave effect on emulsion polymerization of styrene
This article contains original experimental data, figures and methods to the study of Microwave-assisted emulsion polymerization of styrene under the frame of "Enhanced Microwave Synthesis" (EMS), has been examined to investigate the advantages of Microwave (MW) power use in emulsion polymerization (Ergan et al., Eur. Polym. J. 69, 2015, 374-384). For comparative purpose, MW and conventional he...
متن کاملContinuous Miniemulsion Polymerization
Most miniemulsion polymerizations are carried out in batch reactors. However, continuous reactors or continuous reactor trains can provide a high level of consistency when operated at steady state. In this feature article, progress in continuous miniemulsion polymerization will be reviewed. Special attention will be given to issues of monomer diffusion and secondary nucleation. A large portion ...
متن کاملEmulsion Polymerization: From Fundamental Mechanisms to Process Developments
Emulsion polymers are “products by process” whose main properties are determined during polymerization. In this scenario of margins reduction, increasing competition, and public sensitivity to environmental issues, the challenge is to achieve an efficient production of high-quality materials in a consistent, safe, and environmentally friendly way. This highlight reviews the investigations carri...
متن کاملA Kinetic Study of the Emulsion Polymerization of Vinyl Acetate
This report deals with the chemically and the radiation-initiated emulsion polymerization of vinyl acetate. In experiments with potassium persulphate as initiator and sodium lauryl sulphate (SLS) as emulsifier the rate of polymerization is approximately proportional to the square root of initiator concentration and to the 0.25 power of the number of particles. The number of particles is proport...
