Supramolecular Interfacial Polymerization: A Controllable Method of Fabricating Supramolecular Polymeric Materials [PDF]
Angewandte Chemie - International Edition, 2017 AbstractA new method of supramolecular polymerization at the water–oil interface is developed. As a demonstration, an oil‐soluble supramonomer containing two thiol end groups linked by two ureidopyrimidinone units and a water‐soluble monomer bearing two maleimide end groups are employed. Supramolecular interfacial polymerization can be implemented by a

Interfacial Properties of Polymeric Liquids [PDF]
Physical Review Letters, 2000 We show that the variations of the surface tension of polymeric solutions gamma with the molecular weight of the sample M(n), the temperature T, and the volume fraction of monomers straight phi(b) are explained by the self-organization of the long flexible chains that are present in the immediate vicinity of the interface.
