摘要:
The invention concerns composite nanospheres having a diameter ranging between about 50 and 1000 nm plus or minus 5 %, preferably between about 100 and 500 nm plus or minus 5 % and advantageously between 100 and 200 nm plus or minus 5 %, and comprising an essentially liquid core consisting of an organic phase and inorganic nanoparticles, distributed inside the organic phase, and a skin consisting of at least a hydrophilic polymer derived from the polymerisation of at least one water soluble monomer, in particular N-alkylacrylamide or a N-N-dialkylacrylamide; conjugates derived from said nanospheres; their preparation methods and their uses.
摘要:
The invention concerns a method useful for emulsifying a first hydrophobic or hydrophilic phase with viscosity between 1 and 5000 Pa's or higher with a second phase non-miscible with the first phase and in particular concentrated bitumen emulsions. The invention also concerns the resulting emulsions.
