Multiphase polymer dispersions and nanocomposites by catalytic/free radical emulsion polymerization

Free radical emulsion polymerization of styrene or butyl acrylate in the presence of latices of linear, semicrystalline polyethylene prepared by catalytic emulsion polymeriza-

IR spectra of polymers

To investigate the effect of the organic phase in the catalytic emulsion polymerization of butadiene, the organic phase was omitted: the catalyst precursor was directly prepared in

TEM images of a silica/polyethylene composite dispersion using an octenyl-modified silica dispersed in toluene (Table 3,

In the presence of silica modified with octenylsilane 1 (Si1- 1 octen , diameter ∼ 110 nm), the nickel catalyst is able to polymerize ethylene, and a stable SiO 2

Summary: The preparation of aqueous dispersions of very small particles (size < 30 nm) of various polymers (polyethylenes, stereoregular 1,2-polybutadiene, and poly- alkenamers)

in a given catalyst DG ° chain walk and DG ° ins were similar to one another, that is, rates for chain walking and in- sertion were similar (which is likely not the case in 5- Z),

The different grey scales for different particles can be easily rationalized by different viewing angles: If the disc-like particles are nearly parallel to the electron beam,
