A review on the development of liquid chromatography systems for polyolefins
Polyolefins are the most widely produced synthetic polymer commodity and are found in countless applications ranging from bottles, packaging films to bullet-proof jackets, etc.Such widely different applications rely on high variability in the physical properties of polyolefins, which is a result of variations in microstructure, chemical composition and
molar mass. Though polyolefins contain only c...

In-situ emulsion polymerization method on the PMMA/SBA-15 composite.
PMMA/SBA-15 composites were
prepared from three different in-situ emulsion polymerization methods, that is,
batch, semi-continuous and prior-immersion, which differed
from incorporation of monomer methyl methacrylate and mesoporous SBA-15. The
stability of the emulsion polymerization was investigated through monomer
conversion, solid content, coagulum, particle size and particle size
distributio...

Effects of Mesoporous Materials on the MMA Emulsion Polymerization
Rod-like and spherical
mesoporous SBA-15 silica particles were synthesized as pure silicas and surface modified by organosilane coupling
agents firstly, and then the effects of these mesoporous materials
on the critical micelle concentration (CMC) of sodium
dodecylsulfate (SDS), the stabilities of batch and semi-continuous MMA emulsion
polymerizations, and the molecular weights and molecular wei...

Synthesis of Acrylic Emulsion Containing High Hydroxyl Content
Using butyl acrylate (BA), methyl methacrylate (MMA), acrylic acid (AA), and
hydroxylethyl methacrylate as comonomers, along with ammonium persulfate as
initiator, emulsions with high hydroxyl content (10–35%) and carboxyl groups were
synthesized from semi-continuous seed emulsion polymerization methods. Emulsifier
types and levels, reaction temperature, level of hydroxyl monomer, and le...
